Description

Technical Field

[0001] This invention relates to the field of satellite technology, specifically to a double-layer openable SAR satellite configuration and a satellite flipping device. Background Technology

[0002] SAR (Synthetic Aperture Radar) satellites are active Earth observation systems that transmit continuous radio pulses and receive the echoes reflected from the ground to record information about ground features. Due to their all-weather, all-time operation, wide-area imaging, and penetration capabilities, SAR satellites have become an important means of Earth observation. Current SAR satellites mostly use plate-type SAR payload antennas, often employing a CubeSat configuration. However, this configuration results in a large envelope, leading to insufficient rocket space utilization. Therefore, planar satellite configurations are also being used, which have a smaller envelope and can be stacked for launch, maximizing rocket space utilization. However, this flat configuration limits the number of individual units that can be loaded, affecting the satellite's functional expansion. Furthermore, the limited space during satellite assembly makes operation difficult, especially when an internal unit malfunctions and requires disassembly and inspection, necessitating the opening of the top or side panels, which is cumbersome. Furthermore, this flat-structured satellite is extremely inconvenient, especially during assembly and maintenance. During satellite assembly, testing, and subsequent maintenance, operators must complete all tasks—including unit installation, cable laying, and connector connection—within a very limited internal space. When an internal unit malfunctions and requires repair or replacement, the corresponding satellite module often needs to be disassembled. This process is cumbersome, time-consuming, and poses significant risks to personnel and the product.

[0003] Patent application CN117068389A discloses a flattened SAR satellite, comprising: a satellite platform with a trapezoidal overall configuration, two parallel sides and an inclined plane on the other two sides; a SAR payload having a folded and an extended state, wherein the SAR payload is mounted on the top surface of the satellite platform in a flattened, folded state during satellite launch; and solar panels, two of which are mounted on the inclined planes on both sides of the satellite platform, having an extended and a folded state. When the solar panels are in the folded state, they are retracted to the sides of the satellite platform and are located within the coverage area of ​​the orthographic projection of the folded SAR payload. As a preferred embodiment of the flattened SAR satellite, the satellite also includes a satellite unit, which is mounted inside the satellite platform and / or on a mounting surface on the outside of the satellite platform. The top and bottom surfaces of this SAR satellite have sealed covers, which is inconvenient for maintenance.

[0004] Patent application CN119611790A discloses a flat-panel satellite configuration, including a first mounting plate, a second mounting plate opposite to the first mounting plate, and a frame sandwiched between the first and second mounting plates. The first and second mounting plates are located on two opposite sides of the frame. The frame includes several side beams connected end-to-end and several intermediate beams detachably fixed to the inside of the side beams. The intermediate beams divide the interior of the frame into multiple accommodating spaces for accommodating individual satellite units. The satellite's top and ground surfaces are enclosed by covers, which is inconvenient for maintenance. Summary of the Invention

[0005] In order to solve one or more technical problems existing in the prior art, the present invention provides a double-layer openable SAR satellite configuration and a satellite flipping device.

[0006] The technical solution of this invention to solve the above-mentioned technical problems is as follows: This invention provides a double-layer openable SAR satellite configuration, including a surrounding panel, a partition, a first support plate, and a second support plate. Multiple surrounding panels are provided, and these panels are connected end-to-end to form a rectangular cylindrical structure. The partition is vertically fixed to the inner wall of the surrounding panel and divides the rectangular cylindrical structure into an upper assembly space and a lower assembly space. Multiple first support plates are fixed within the upper assembly space, and multiple second support plates are fixed within the lower assembly space. The multiple first support plates are vertically fixed to the partition and the surrounding panel, respectively. The multiple first support plates divide the upper assembly space into multiple upward-opening upper assembly compartments. The multiple second support plates are vertically fixed to the partition and the surrounding panel, respectively, and divide the lower assembly space into multiple downward-opening lower assembly compartments.

[0007] The beneficial effects of the present invention are: the double-layer openable SAR satellite configuration of the present invention, while maintaining the external flat plate configuration, achieves a doubling of internal space through a unique double-layer structure and open design, which also makes the satellite assembly, testing and maintenance operations simple and convenient.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, multiple antenna mounting brackets are fixed within the upper assembly space. The lower end of each antenna mounting bracket is vertically fixed to the partition plate, and the upper end of each antenna mounting bracket is flush with the upper end face of the first support plate or extends from the upper assembly compartment.

[0010] The advantage of adopting the above-mentioned further solution is that it facilitates antenna assembly by setting up multiple antenna mounting brackets.

[0011] Furthermore, the sidewall of the antenna mounting bracket is directly fixed to the adjacent enclosure or fixed to the adjacent enclosure via a first auxiliary bracket; the antenna mounting bracket adopts a long rectangular structure with a hollowed-out triangular stabilizing structure.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by setting the first auxiliary bracket, the position of the antenna mounting bracket on the partition can be set according to the size of the antenna, and a stable connection with the partition can be achieved by using the first auxiliary bracket.

[0013] Furthermore, the multiple enclosure panels are respectively a first enclosure panel, a second enclosure panel, a third enclosure panel, and a fourth enclosure panel. The first enclosure panel and the third enclosure panel are arranged in parallel with each other and have the same length. The second enclosure panel and the fourth enclosure panel are arranged in parallel with each other and have the same length. The length of the first enclosure panel is greater than the length of the second enclosure panel. Multiple antenna mounting brackets are fixed near the first enclosure panel and multiple antenna mounting brackets are fixed near the third enclosure panel. At least one antenna mounting bracket is provided in each upper assembly compartment.

[0014] The beneficial effect of adopting the above-mentioned further solution is that setting up two rows of antenna mounting brackets adjacent to the longer enclosure facilitates the overall assembly of the antenna.

[0015] Furthermore, multiple separate seat mounting brackets are fixed in the lower assembly space. The lower end of the separate seat mounting bracket is vertically fixed to the partition plate, and the upper end of the separate seat mounting bracket is flush with the lower end face of the second support plate or extends out from the lower assembly compartment.

[0016] Furthermore, the side wall of the separation seat mounting bracket is directly fixed to the adjacent enclosure or fixed to the adjacent enclosure through a second auxiliary bracket; the separation seat mounting bracket adopts a long rectangular structure with a hollow triangular stabilizing structure.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting a second auxiliary bracket, the position of the separation seat mounting bracket on the partition can be set according to the assembly position of the mounting seat, and a stable connection with the enclosure can be achieved by using the second auxiliary bracket.

[0018] Furthermore, the multiple enclosure panels are respectively a first enclosure panel, a second enclosure panel, a third enclosure panel, and a fourth enclosure panel. The first enclosure panel and the third enclosure panel are arranged in parallel with each other and have the same length. The second enclosure panel and the fourth enclosure panel are arranged in parallel with each other and have the same length. The length of the first enclosure panel is greater than the length of the second enclosure panel. Multiple separation seat mounting brackets are fixed near the first enclosure panel and multiple separation seat mounting brackets are fixed near the third enclosure panel. At least one separation seat mounting bracket is provided in each lower assembly compartment.

[0019] Furthermore, the partition plate is provided with a plurality of first through holes, the connection position between the first support plate and the partition plate is provided with a plurality of second through holes, and the connection position between the second support plate and the partition plate is provided with a plurality of third through holes. The plurality of first through holes, the plurality of second through holes and the plurality of third through holes are arranged in a one-to-one correspondence and are interconnected with each other. Corner frame fixing supports are fixed at the connection between the first support plate and the surrounding plate, the connection between two connected first support plates, the connection between the second support plate and the surrounding plate, and the connection between two connected second support plates.

[0020] The advantages of adopting the above-mentioned further solution are: by setting the first through hole, the second through hole and the third through hole, it is convenient to run the wires, etc.

[0021] Furthermore, it also includes an antenna, a solar array, a platform integrated electronic payload, a load cell electrical payload, and a data transmission unit. The antenna is fixed above the upper assembly compartment, and the platform integrated electronic payload, the load cell electrical payload, and the data transmission unit are respectively installed in multiple lower assembly compartments. The solar array is connected to the outer walls of two oppositely arranged enclosure panels.

[0022] The advantages of adopting the above-mentioned further solution are as follows: Important individual units, and those most likely to require maintenance later, are placed in the lower layer. Previously, when an internal unit malfunctioned and needed repair or replacement, the corresponding satellite module often needed to be disassembled, a cumbersome and time-consuming process that posed significant risks to personnel and products. This double-layer open configuration allows for direct maintenance of any unit that malfunctions, without the need to disassemble the SAR antenna. The reason it's not installed in the upper layer is that if it were, the SAR antenna would need to be removed for repair, and subsequent reinstallation would require releveling, increasing workload. If a unit in the lower layer needs repair, since there is no base plate, the satellite can simply be rotated 180 degrees so the lower layer faces upwards for repair.

[0023] The present invention also provides a satellite flipping device, including a double-layer openable SAR satellite configuration as described above, and a flipping vehicle. The flipping vehicle has a flipping channel with an open upper side. At least one side of the flipping channel is provided with a flipping power mechanism and a positioning mechanism. The double-layer openable SAR satellite configuration is placed in the flipping channel. The double-layer openable SAR satellite configuration is connected to the power output end of the flipping power mechanism and can be flipped under the drive of the flipping power mechanism or positioned by the positioning mechanism.

[0024] The beneficial effects of this invention are: by setting up a tilting cart, a double-layer openable SAR satellite configuration can be set in the tilting channel of the tilting cart, and the satellite can be rotated 180 degrees. When it is necessary to assemble or maintain the lower layer unit, the tilting cart is used with the lower layer facing upwards, and when it is necessary to assemble or maintain the upper layer unit, the tilting cart is used with the upper layer facing upwards.

Detailed Implementation

[0027] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0028] Example 1 like Figures 1-7As shown, this embodiment of a double-layer openable SAR satellite configuration includes a surrounding panel, a partition 2, a first support plate 3, and a second support plate 31. Multiple surrounding panels are connected end-to-end to form a rectangular cylindrical structure. The partition 2 is vertically fixed to the inner wall of the surrounding panel and divides the rectangular cylindrical structure into an upper assembly space and a lower assembly space. Multiple first support plates 3 are fixed within the upper assembly space, and multiple second support plates 31 are fixed within the lower assembly space. The multiple first support plates 3 are vertically fixed to the partition 2 and the surrounding panel, respectively. The multiple first support plates 3 divide the upper assembly space into multiple upward-opening upper assembly compartments. The multiple second support plates 31 are vertically fixed to the partition 2 and the surrounding panel, respectively, and divide the lower assembly space into multiple downward-opening lower assembly compartments.

[0029] In this embodiment, the multiple first support plates 3 can be arranged perpendicularly to each other; for example, four first support plates 3 can be set to form four upper assembly compartments. Similarly, the multiple second support plates 31 can be arranged perpendicularly to each other; for example, four second support plates 31 can be set to form four lower assembly compartments. The assembly compartments can be evenly or unevenly arranged. This arrangement allows for the installation of more individual units, expanding satellite functionality. The size of the compartments can also be adjusted according to the actual size requirements of the individual units.

[0030] In this embodiment, the height of the upper and lower layers can be adjusted according to the actual height of each individual unit, and the two layers can be different to maximize space utilization. For example, the lower layer can be set higher to install larger and heavier units, while the upper layer can install smaller, lighter units. An antenna (SAR antenna) is also installed on the upper layer to balance the overall satellite's center of mass, keeping it as low as possible for better stability. The overall satellite configuration is nearly flat, with a low center of mass, optimized transmission paths, and small sinusoidal and stochastic mechanical responses, effectively resisting the effects of launch vehicle vibrations. The satellite is divided into upper and lower layers, without top and bottom plates, providing a wide field of view when installing individual units, allowing for direct observation of the installation status without blind spots, facilitating final assembly.

[0031] This embodiment of a dual-layer openable SAR satellite configuration, while maintaining the external flat panel configuration, achieves a doubling of internal space through a unique dual-layer structure and open design, which also makes the satellite assembly, testing and maintenance operations simple and convenient.

[0032] Example 2 Based on Example 1, this example provides a preferred layout scheme for the upper assembly space. For example... Figure 1 and 2As shown, in this embodiment, multiple antenna mounting brackets 21 are fixed in the upper assembly space. The lower end of each antenna mounting bracket 21 is vertically fixed to the partition 2, and the upper end of each antenna mounting bracket 21 is flush with the upper end face of the first support plate 3 or extends from the upper assembly compartment. By providing multiple antenna mounting brackets, antenna assembly is facilitated.

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides an optional assembly scheme for the antenna mounting bracket 21. The sidewall of the antenna mounting bracket 21 is directly fixed to the adjacent partition or fixed to the adjacent partition via a first auxiliary bracket 22. The antenna mounting bracket 21 adopts a long rectangular structure with a hollowed-out triangular stabilizing structure. By setting the first auxiliary bracket, the position of the antenna mounting bracket on the partition can be set according to the size of the antenna, and a stable connection with the partition can be achieved using the first auxiliary bracket.

[0034] like Figure 1 and Figure 2 As shown, the multiple enclosure panels in this embodiment are a first enclosure panel 1, a second enclosure panel 11, a third enclosure panel 12, and a fourth enclosure panel 13. The first enclosure panel 1 and the third enclosure panel 12 are arranged parallel to each other and have the same length. The second enclosure panel 11 and the fourth enclosure panel 13 are also arranged parallel to each other and have the same length. The length of the first enclosure panel 1 is greater than the length of the second enclosure panel 11. Multiple antenna mounting brackets 21 are fixed near the first enclosure panel 1 and multiple antenna mounting brackets 21 are fixed near the third enclosure panel 12. At least one antenna mounting bracket 21 is provided in each upper assembly compartment. Two rows of antenna mounting brackets are arranged adjacent to the longer enclosure panels to facilitate the overall assembly of the antenna.

[0035] Example 3 Based on Embodiment 1 or Embodiment 2, this embodiment provides a preferred arrangement of the lower assembly space. For example... Figure 3 and Figure 4 As shown, in this embodiment, a plurality of separate seat mounting brackets 23 are fixed in the lower assembly space. The lower end of the separate seat mounting bracket 23 is vertically fixed on the partition plate 2, and the upper end of the separate seat mounting bracket 23 is flush with the lower end face of the second support plate 31 or extends out from the lower assembly compartment.

[0036] like Figure 3 and Figure 4As shown, this embodiment provides an optional assembly scheme for the split seat mounting bracket 23. The side wall of the split seat mounting bracket 23 is directly fixed to the adjacent partition or fixed to the adjacent partition via a second auxiliary bracket 24; the split seat mounting bracket 23 adopts a long rectangular structure with a hollow triangular stabilizing structure. By setting the second auxiliary bracket, the position of the split seat mounting bracket on the partition can be set according to the assembly position of the mounting seat, and a stable connection with the partition can be achieved using the second auxiliary bracket.

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, the multiple enclosure panels are a first enclosure panel 1, a second enclosure panel 11, a third enclosure panel 12, and a fourth enclosure panel 13. The first enclosure panel 1 and the third enclosure panel 12 are arranged in parallel with each other and have the same length. The second enclosure panel 11 and the fourth enclosure panel 13 are arranged in parallel with each other and have the same length. The length of the first enclosure panel 1 is greater than the length of the second enclosure panel 11. Multiple separation seat mounting brackets 23 are fixed near the first enclosure panel 1 and multiple separation seat mounting brackets 23 are fixed near the third enclosure panel 12. At least one separation seat mounting bracket 23 is provided in each lower assembly compartment.

[0038] In this embodiment, the height of the separation seat mounting bracket 23 is the same as the height of the second support plate 31. A cover plate 9 can be installed at the bottom of the enclosure, that is, at the bottom of each lower assembly compartment. The cover plate 9 can expose the corner frame fixing support 7, the separation seat mounting bracket 23 and the second auxiliary bracket 24 described in the following embodiment. Then, the separation seat 8 is fixed on the separation seat mounting bracket 23. The separation seat 8 is used for the separation of the rocket and the satellite. After the rocket is launched into its predetermined orbit, the satellite is ejected by the separation mechanism on the rocket. The separation seat is used for the connection and separation of the satellite and the rocket. During the rocket and satellite launch phase, the satellite and the rocket are connected through the separation seat. When the rocket reaches the predetermined orbit of the satellite, the separation seat is powered on and unlocked. Under the action of the separation spring inside the separation seat, the satellite is pushed out and enters the predetermined orbit.

[0039] Example 4 Based on any of the above embodiments, in this embodiment, the partition 2 is provided with multiple first through holes 25, the connection position between the first support plate 3 and the partition 2 is provided with multiple second through holes 32, and the connection position between the second support plate 31 and the partition 2 is provided with multiple third through holes 33. The multiple first through holes 25, multiple second through holes 32, and multiple third through holes 33 are arranged in a one-to-one correspondence and are interconnected. Corner frame fixing supports 7 are fixed at the connection points between the first support plate 3 and the surrounding plate, the connection points between two connected first support plates 3, the connection points between the second support plate 31 and the surrounding plate, and the connection points between two connected second support plates 31. By providing the first through holes, second through holes, and third through holes, wiring is facilitated.

[0040] To ensure the strength of the entire star's double-layer structure, each pair of plates can be connected and fixed by corner frame fixing support 7, thereby increasing the overall strength of the star structure.

[0041] Example 5 Based on any of the above embodiments, the dual-layer openable SAR satellite configuration of this embodiment further includes an antenna 4, a solar array 5, a platform integrated electronic payload, a payload electrical payload, and a data transmission unit. The antenna 4 is fixed above the upper assembly compartment, and the platform integrated electronic payload, payload electrical payload, and data transmission unit are respectively installed in multiple lower assembly compartments. The solar array 5 is connected to the outer walls of two oppositely arranged enclosures. Placing important units, and those most likely to require maintenance later, in the lower layer often requires disassembling the corresponding satellite module when a unit malfunctions and needs repair or replacement. This is a cumbersome and time-consuming process, posing significant risks to personnel and products. This dual-layer open configuration allows for direct maintenance of units without disassembling the SAR antenna. The reason for not installing them in the upper layer is that if they were, the SAR antenna would need to be removed for repair, and subsequent re-leveling would increase workload. If a lower-level unit needs maintenance, since there is no base plate, the satellite only needs to be rotated 180 degrees so that the lower level is facing upwards for maintenance.

[0042] This embodiment places critical units, those most likely to require maintenance later, in the lower layer. Previously, when an internal unit malfunctioned and needed repair or replacement, the corresponding satellite module often needed to be disassembled, a cumbersome and time-consuming process that posed significant risks to personnel and the product. This double-layer open configuration allows for direct maintenance of malfunctioning units without disassembling the SAR antenna. The reason for not placing them in the upper layer is that doing so would require removing the SAR antenna for repair, and subsequent re-leveling would further increase workload. If a unit in the lower layer needs repair, the absence of a base plate allows for simple 180° rotation of the satellite, with the lower layer facing upwards, for easy access.

[0043] In this embodiment, multiple antenna mounting brackets 21 are fixed within the upper assembly space. Since there is no top plate as a SAR payload mounting plate, the SAR payload deployment mechanism (i.e., the deployable antenna structure) is connected to the corresponding antenna mounting brackets (the four antenna mounting brackets in the middle) via clamping seats. The specific size and form of the antenna mounting brackets are determined by the satellite size and the spacing between the clamping seats of the SAR payload deployment mechanism. If the short side of the SAR payload (antenna) is similar in length to the short side of the satellite, the antenna mounting bracket can be used directly. The antenna mounting bracket is tightly connected to the surrounding plate to ensure structural strength. If the clamping seat spacing is small, it is connected and fixed to the front and rear surrounding plates via a first auxiliary bracket 22; otherwise, the bracket would be too large and occupy too much space. The bracket form here adopts a rectangular hollow triangular stabilizing structure, balancing weight reduction and triangular combination stabilizing structure. The SAR payload mentioned here refers to antenna 4, but it can also be other payloads. The SAR payload deployment mechanism can adopt a deployment and separation mechanism commonly used for antennas, including a deployment hinge and a separation and release mechanism. Figure 5 As shown, after the middle part of the antenna 4 is folded, it can be fixed to the antenna mounting bracket 21 in the middle of the first enclosure 1 and the second enclosure 11 by the load fixing seat 42. The two sides of the antenna 4 can be connected to the antenna mounting brackets 21 at both ends of the first enclosure 1 and the second enclosure 11 by the load unfolding mechanism 41.

[0044] The lower layer of the dual-layer openable SAR satellite configuration is similar to the upper layer. A separation mount needs to be installed beneath the lower layer. Since there is no base plate, the separation mount is secured using a mounting bracket, the same structure as the SAR payload mounting bracket. A cover plate can be installed at the bottom of the lower layer. This cover plate is not mandatory and can be determined based on the satellite's specific needs. If the lower layer unit requires effective protection against space radiation and space debris, maintains internal temperature, and provides a closed, safe environment, a cover plate is installed. This cover plate consists of four sections, corresponding to the size of the four compartments. The cover plate connects to the satellite platform. When needed, the corresponding cover plate is simply removed, making it simple and practical. The cover plate also strengthens the overall structure.

[0045] This embodiment expands the platform's functional capacity. By adopting a double-layer frame structure, it maintains a flat panel configuration in the folded state while overcoming the shortcomings of insufficient internal volume in traditional single-layer configurations, laying the physical foundation for carrying more functional units and improving the overall satellite performance. It greatly enhances the convenience of assembly and maintenance. Through an openable configuration design, this embodiment transforms the traditional enclosed cabin into an open operating space, allowing personnel to directly access all units from the top or bottom for work, fundamentally solving the problems of narrow operating space, poor visibility, and the need for repeated disassembly and reassembly of large components for maintenance in existing configurations.

[0046] Example 6 This embodiment provides a satellite flipping device, including a double-layer openable SAR satellite configuration as described in any of the above embodiments, and a flipping vehicle 6. The flipping vehicle 6 has a flipping channel with an open upper side. At least one side of the flipping channel is provided with a flipping power mechanism 63, and at least one side of the flipping channel is also provided with a positioning mechanism 65. The double-layer openable SAR satellite configuration is placed in the flipping channel. The double-layer openable SAR satellite configuration is connected to the power output end of the flipping power mechanism 63 and can be flipped under the drive of the flipping power mechanism 63 or positioned by the positioning mechanism 65.

[0047] Specifically, in this embodiment, the power output end of the flipping power mechanism 63 is connected to a turntable 64. The turntable 64 is fixed on the side wall of the double-layer openable SAR satellite configuration, specifically in the middle of the first enclosure 1 or the third enclosure 12. The flipping power mechanism 63 includes a motor and a reduction gear set. The output shaft of the motor is connected to the reduction gear set and drives the reduction gear set to run. The power output end of the reduction gear set is vertically fixed to the center of the turntable 64 and drives the turntable 64 to rotate, thereby driving the double-layer openable SAR satellite configuration to rotate.

[0048] This embodiment of the double-layer open-type satellite configuration differs from traditional satellites during assembly. A tilting cart allows the satellite to be rotated 180°. When assembling or maintaining the lower-layer unit, the tilting cart is used with the lower layer facing upwards; conversely, when assembling or maintaining the upper-layer unit, the tilting cart is used with the upper layer facing upwards. The tilting cart is connected to the double-layer open-type SAR satellite configuration via a turntable. The turntable is connected to a motor on the tilting cart via a reduction gear set. Controlling the rotation of the turntable controls the rotation of the double-layer open-type SAR satellite configuration. After rotation, to ensure the structural strength of the SAR satellite is not compromised, a positioning mechanism is installed on the cart body. Four positioning mechanisms connect and fix the front and rear panels of the SAR satellite, providing support, fixation, and limiting, ensuring the SAR satellite is evenly stressed.

[0049] Specifically, the tilting vehicle 6 in this embodiment includes a base frame, a first tilting bracket 61, and a second tilting bracket 62. The first tilting bracket 61 and the second tilting bracket 62 are respectively vertically fixed on the base frame, and are arranged in parallel at intervals to form the tilting channel. A tilting power mechanism 63 can be installed on each tilting bracket, or a tilting power mechanism can be installed on one tilting bracket and a rotating mechanism can be installed on the other tilting bracket for rotatable connection with the corresponding enclosure. The positioning mechanism in this embodiment includes a positioning plate and a slider. The positioning plate is fixed on the slider, and the slider is slidably connected to the first tilting bracket 61 or the second tilting bracket 62. The first tilting bracket 61 or the second tilting bracket 62 can adopt a slide rail structure, and the slider can move horizontally left and right. Two positioning mechanisms can be provided on each tilting bracket.

[0050] This embodiment uses a tilting cart to set up a double-layer openable SAR satellite configuration within the tilting channel of the tilting cart, allowing the satellite to be rotated 180 degrees. When it is necessary to assemble or maintain the lower layer unit, the tilting cart is used with the lower layer facing upwards; when it is necessary to assemble or maintain the upper layer unit, the tilting cart is used with the upper layer facing upwards.
