[0002] With the rapid development of satellite technology, there are more and more types of satellites, and satellites are widely used in many fields. In satellite design, satellite manufacturing, and satellite system operation, a large amount of experimental data needs to be provided by computer simulation.

The appearance of the simulated satellite is as close as possible to the satellite in orbit, and it is also equipped with solar panels, thrusters, etc., so the movement and steering functions of the simulated satellite can also be tested.

[0004] However, the existing satellite simulation platform is set on the ground and is affected by the gravity environment, which is still quite different from the space environment. In the thruster of the simulated satellite, the propellant is affected by gravity and deposited at the bottom of the container, so it is not convenient to export it in the direction required for propulsion.

DETAILED DESCRIPTION

[0041] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] At present, with the continuous progress in the aerospace field, satellite-related technologies are developing faster and faster. In space, satellite propulsion and steering are the most basic functions that require the most precise control. The current propulsion methods of satellites in orbit include cold gas propulsion, liquid propulsion, solid propulsion, etc., which mainly use the reaction force generated by the movement of gas or liquid as thrust. When the ground-based satellite simulation platform simulates and studies satellites in orbit, in order to reduce the cost of the test, water or aqueous solutions are generally used instead of expensive propellants. By drawing on the working principle of the atomizer, simulation tests of liquid propulsion systems can be carried out.

[0043] Existing nebulizers include but are not limited to jet nebulizers, ultrasonic nebulizers, vibrating mesh nebulizers, and the like.

[0044] The jet nebulizer uses compressed air or oxygen to form a high-speed airflow through a small tube. The negative pressure generated drives the liquid to be sprayed onto the baffle, and the liquid is broken into small aerosol particles under high-speed impact, thus achieving the atomization effect.

[0045] The ultrasonic nebulizer uses a piezoelectric converter to convert electrical signals into ultrasonic waves, generating high-frequency (1.2-2.4MHz) acoustic vibrations, which act on the solution, destroying the surface of the solution to produce oscillation waves, thereby generating aerosols on the surface of the solution to achieve a nebulization effect.

[0046] The vibrating mesh nebulizer combines the principles of an ultrasonic nebulizer and also uses a piezoelectric converter to vibrate a circular plate containing several funnel holes at 130kHz (approximately 1 / 10 of the vibration frequency of an ultrasonic nebulizer), causing the circular plate to vibrate up and down with an amplitude of 1-2μm. This movement pumps the liquid through the funnel holes and breaks it down into fine particles, achieving an atomization effect.

[0047] It can be seen that the working process of various atomizers is to break up the liquid into small particles, and give the small particles a certain initial velocity while atomizing, so as to achieve a spraying effect.

[0048] However, the mist outlet direction of the existing atomizer is fixed and inconvenient to adjust; in some fields, in order to adjust the spray direction, a conduit is added to the atomization port, but the conduit will cause water vapor condensation and hinder the movement of droplets.

[0049] In addition, the liquid in the atomizer is generally sucked out through the water-absorbing core, which is made by compressing a large amount of cotton fibers. Both ends can absorb water, and the water absorption is stronger than that of ordinary water-absorbing materials. However, once the dense cotton fibers are bent at too large an angle, local extrusion will occur, forming a water-blocking block, resulting in the blocking of the water path in the water-absorbing core, and the water absorption effect will be greatly reduced or even completely ineffective. Due to the influence of the earth's gravity, the liquid always settles at the bottom of the container, so the existing atomizer usually sets the outlet at the top, so that the top of the water-absorbing core is aligned with the outlet, and the bottom is placed at the bottom of the container, so as to fully absorb the liquid in the container.

[0050] In the aerospace field, thrusters are used to propel satellites to turn and change orbits, and require the ability to flexibly change thrust direction. Therefore, the propulsion work of liquid thrusters is quite different from that of ordinary atomizers, and the difference in their operating environments is huge. Therefore, conventional replacements or combinations alone cannot truly simulate the propulsion and movement process of in-orbit satellites.

[0051] In summary, the existing atomization product devices mainly set the mist outlet on the top of the water storage tank to spray droplets upward, which cannot effectively simulate the propulsion direction of the satellite and cannot be combined with the satellite simulation platform for testing. The atomization process cannot meet the simulation requirements, affecting the authenticity of the simulation, which will lead to inaccurate test data and poor display effects. The present invention uses structural design to allow the atomized droplets to be sprayed in a horizontal or inclined direction to generate a lateral propulsion force, which more realistically simulates the propulsion effect of the satellite.

[0052] See also Figure 1 , Figure 2 , Figure 3 and Figure 4In one embodiment of the present invention, a vertical angle atomizing water tank device is disclosed, which is used for a satellite simulation platform; wherein, the device comprises a box body 10, a water absorption strip 20, an ultrasonic atomizing assembly 30, a beam tube 40, a humidity sensor 50 and a control panel 60, wherein the box body 10 is connected to the satellite simulation platform; a water storage chamber 11 is formed in a hollow space in the box body 10; a water outlet channel 12 is provided on one side of the water storage chamber 11, and at least two limit baffles 13 are protrudingly provided on the other side; a limit groove 14 is formed between two adjacent limit baffles 13; the water absorption strip 20 is arranged in the limit groove 14; one end of the water absorption strip 20 extends to the bottom of the water storage chamber 11 part, and contacts with the bottom surface of the water storage chamber 11; the other end of the water absorption strip 20 extends out of the limiting groove 14, is bent and inserted into the water outlet channel 12; the ultrasonic atomization component 30 is connected to the box body 10, and is arranged at one end of the water outlet channel 12 away from the water storage chamber 11; the ultrasonic atomization component 30 is fitted with the water absorption strip 20, and is used to atomize and spray liquid to simulate satellite propulsion and orbit change; the beam tube 40 is connected to the box body 10, and is nested on the ultrasonic atomization component 30; the humidity sensor 50 is arranged on the inner wall of the beam tube 40; the control board 60 is electrically connected to the ultrasonic atomization component 30 and the humidity sensor 50.

[0053] The vertically angled atomizing water tank device disclosed in this embodiment is applied to a satellite simulation platform and used as a thruster of a simulated satellite. When the satellite simulation platform is tested, the box 10 is set on the main body of the satellite simulation platform. During assembly, in order to be close to the actual structure of the satellite in orbit, the box 10 can be set at the rear end of the simulated satellite, and the water outlet channel 12 faces the rear of the simulated satellite to spray liquid backwards and provide forward thrust. Liquid (such as water or a mixed aqueous solution of multiple substances) is stored in the box 10 as a substitute for propellant to simulate the steering, orbit change and other operations of the satellite in orbit, reduce simulation costs, and improve the safety of the test.

[0054] like Figure 1 As shown, in one implementation of this embodiment, the box body 10 can be set as a cube or a cuboid, and the side wall of the water storage chamber 11 is provided with a horizontal water outlet channel 12; in another implementation of this embodiment, the water outlet channel 12 can also be inclined or vertically arranged; the limit baffle 13 is arranged on the side wall of the other side of the water storage chamber 11. During assembly, the water absorption strip 20 extends upward from the bottom surface of the water storage chamber 11, and turns from one side to the other side, gradually bending from the longitudinal extension to the horizontal or inclined extension. Since it spans the entire water storage chamber 11, the bending angle formed is large, so the transition is smooth, avoiding excessive bending of the water absorption strip 20, reducing the risk of water channel blockage, and allowing the water absorption strip 20 to maintain normal water absorption function.

[0055] Specifically, the water absorption strip 20 is constrained by the limiting baffle 13 in the box body 10 so that the water absorption strip 20 is fixed and can extend to the bottom surface of the water storage chamber 11, so as to achieve the effect that as long as there is liquid in the box body 10, it can be absorbed by the water absorption strip 20, thereby reducing the deposition of waste water in the box body 10 and improving the utilization efficiency of the liquid in the box body 10.

[0056] Moreover, in this embodiment, the end of the water absorption strip 20 is inserted into the water outlet channel 12 and can remain stable to ensure that the water in the box 10 contacts the ultrasonic atomization assembly 30, thereby improving the efficiency of ultrasonic atomization.

[0057] In addition, when the water absorbing strip 20 is partially bent, some elastic potential energy will exist. In this embodiment, the water absorbing strip 20 is constrained by the limiting baffle 13, so that the water absorbing strip 20 can be fixed to prevent the water absorbing strip 20 from shifting due to the rebound force.

[0058] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in another implementation of the present embodiment, it is disclosed that a plurality of water outlet channels 12 may be provided on the box body 10, for example, three water outlet channels 12 may be provided in a triangular shape, four water outlet channels 12 may be provided in a rectangular array, six water outlet channels 12 may be provided in a hexagonal shape, etc. According to the structure of the simulated satellite simulated by the satellite simulation platform, different numbers of water outlet channels 12 may be provided to simulate the effect of coordinated propulsion of multiple thrusters, further improve the degree of simulation, and facilitate ground tests or demonstrations. Adaptively, a plurality of water absorbing strips 20 may be provided in the water storage chamber 11, and the length of the water absorbing strips 20 may be adaptively adjusted according to the position of the water outlet channel 12, so that one end of the water absorbing strip 20 is kept in contact with the bottom surface of the water storage chamber 11, and the other end is inserted into the water outlet channel 12.

[0059] It should also be noted that in this embodiment, the shape of the box 10 is only exemplified as a cube, but it is not exhaustive. As long as other types of boxes 10 can achieve the technical effects disclosed in this application, they should also be within the scope of protection of this application as equivalent replacements of the inventive concept. For example, according to the simulation needs, the box 10 can also be set to a triangle, a pentagon, or even a special shape. For example, the box 10 is set to a starfish shape, imitating the multiple tentacles of a starfish, and a water absorbent strip 20 is inserted into the far end of each "tentacle" of the box 10, thereby separating the multiple water absorbent strips 20, and each water absorbent strip 20 absorbs the liquid in its own "tentacle", increasing the uniformity of absorption and avoiding the problem of local water shortage.

[0060] The limit baffle 13 disclosed in this embodiment can be integrally formed with the box body 10 and manufactured by 3D printing. A water inlet can be set on the box body 10, and a hole plug can be printed separately, and liquid is poured through the water inlet, and then sealed with a hole plug. At least two adjacent limit baffles 13 in the water storage chamber 11 are arranged side by side, and the whole is U-shaped, with openings at both ends, and one side facing the center of the water storage chamber 11 is also open, so the structure is simple, and it is convenient to insert the water absorption strip 20 sideways, and extend the water absorption strip 20 from the upper and lower ends. In addition, the limit baffle 13 is arranged in a straight line, which reduces the difficulty of 3D printing.

[0061] In another implementation of this embodiment, the box body 10 can also be formed by a mold, a cover plate can be provided on the top of the box body 10, the box body 10 is formed twice, and after being formed, a sealing strip is provided at the top opening of the box body 10. After the liquid is poured into the water storage chamber 11, the cover plate is closed on the top of the box body 10, and the sealing strip is pressed tightly, so that the water storage chamber 11 reaches a sealed state, and the box body 10 is prevented from leaking during the simulation process.

[0062] In the actual manufacturing process, the molding method of the box body 10 can be selected by comprehensively considering the production needs and production costs to optimize the batch production process.

[0063] Specifically, the absorbent strip 20 disclosed in this embodiment includes but is not limited to a high-pressure cotton swab made of a large amount of cotton fibers, has strong water absorption and a long service life, and can be used for a long time in a liquid environment.

[0064] Specifically, the ultrasonic atomization assembly 30 disclosed in this embodiment pumps water or a mixed solution onto a vibrating screen plate having a funnel hole through ultrasonic vibration, so that the water or a mixed solution passes through the funnel hole and is decomposed into fine particles and ejected at a certain speed to form a thrust.

[0065] Specifically, Figure 1 and Figure 2 As shown, the present application also reduces sputtering and increases the control accuracy of the propulsion direction by setting a beam tube 40; the humidity sensor 50 in the beam tube 40 can sense the atomization amount of the liquid, play a role in real-time monitoring, and send an alarm signal to the control board 60 in time when there is a lack of water in the box 10. The control board 60 is a printed circuit board, which is fixed to the outer wall of the box 10 by screwing, welding or bonding, preferably on the side of the box 10 away from the water outlet channel 12, and is connected to the humidity sensor 50 and the ultrasonic atomization assembly 30 by bypassing the outer wall of the box 10 through a wire (not shown in the drawings), which can receive the monitoring data of the humidity sensor 50 and control the opening and closing of the ultrasonic atomization assembly 30.

[0066] In summary, the vertical angle atomizing water tank device disclosed in this embodiment extends the bottom end of the water absorption strip 20 to the bottom of the water storage chamber 11, thereby increasing the utilization rate of the solution in the box body 10; the water absorption strip 20 is arranged across the water storage chamber 11, thereby reducing the bending angle of the water absorption strip 20 and maintaining the water path for water absorption normal; the top end of the water absorption strip 20 is inserted into the water outlet channel 12 and contacts with the ultrasonic atomizing assembly 30, thereby stabilizing the atomization efficiency; and the beam tube 40 and the humidity sensor 50 are also used to improve the control and detection of the atomized liquid, thereby ultimately improving the simulation effect, vividly demonstrating the propulsion and orbit change operations of the on-orbit satellite, and being beneficial to improving the authenticity and reliability of ground tests and reducing the test and demonstration costs.

[0067] like Figure 2 and Figure 4 As shown, as an implementation of this embodiment, the limit baffle 13 is disclosed to extend along the height direction of the box body 10; and the top surface of the limit baffle 13 is located below the end surface of the water outlet channel 12 connected to the water storage chamber 11.

[0068] In this embodiment, the arrangement of the limiting baffle 13 determines the extension direction of the limiting groove 14, thereby constraining the position of the water absorption strip 20. The water absorption strip 20 is arranged along the height direction of the box body 10 to transport the liquid on the bottom surface of the water storage chamber 11 to the water outlet channel 12 with the shortest distance, thereby reducing the liquid residue in the water absorption strip 20, efficiently utilizing the liquid in the box body 10, and improving the utilization rate of the liquid.

[0069] In this embodiment, the water absorbing strip 20 starts to bend after extending out of the top of the limiting baffle 13 and extends toward the water outlet channel 12. The port of the water outlet channel 12 is above the limiting baffle 13, and the direction of the line connecting the two is inclined, not horizontal. In other words, the water absorbing strip 20 is prevented from bending from a vertical state to a horizontal state. There is no 90° dead angle, and the bending angle is reduced. The curvature of the water absorbing strip 20 is small, thereby preventing the water channel from being blocked and maintaining good water absorption capacity.

[0070] Specifically, as another implementation of this embodiment, it is disclosed that the diameter of the water absorbing strip 20 is 5-8 mm; the shape of the water outlet channel 12 is a straight cylinder, and the length of the water outlet channel 12 is 10-15 mm.

[0071] In this embodiment, since the ultrasonic atomization assembly 30 realizes the atomization and spraying functions by breaking up the liquid on the end surface of the water absorption strip 20, the cross-sectional area of ​​the water absorption strip 20 will inevitably affect the atomization efficiency of the ultrasonic atomization assembly 30; therefore, the diameter of the water absorption strip 20 needs to be greater than or equal to 5 mm to fully absorb the liquid, match the working frequency of the ultrasonic atomization assembly 30, and improve the atomization effect, thereby generating sufficient propulsion force. In addition, the cross-sectional area of ​​the water absorption strip 20 is set to be less than or equal to 8 mm to reduce the solution residue in the water absorption strip 20 and reduce production costs.

[0072] In addition, in this embodiment, the water absorption strip 20 can only fully function when the end face of the water absorption strip 20 fits the ultrasonic atomization assembly 30, so the water absorption strip 20 in the water outlet channel 12 should be arranged in a straight line to avoid bending. The water absorption strip 20 bends from the other side of the water storage chamber 11 to the side of the water outlet channel 12. If the length inserted into the water outlet channel 12 is less than the diameter of the water absorption strip 20, the end is affected by its own elasticity and is easily deformed, which may affect the fit of the end face with the ultrasonic atomization assembly 30. The length of the water outlet channel 12 is set to be greater than the diameter of the water absorption strip 20, and the length of the end of the water absorption strip 20 inserted into the water outlet channel 12 is 10-15 mm, so it is arranged in a straight line, reducing the impact of bending, thereby ensuring that the ultrasonic atomization assembly 30 is in close contact with the end face of the water absorption strip 20 to achieve the expected atomization effect.

[0073] Specifically, in this embodiment, the cross-section of the water outlet channel 12 is the same as the cross-section of the water absorption strip 20, and the diameter of the cross-section of the water outlet channel 12 is slightly larger than the diameter of the cross-section of the water absorption strip 20, or the two are equal. The water absorption strip 20 remains stable and avoids displacement, so that the ultrasonic atomization assembly 30 and the water absorption strip 20 remain aligned to maintain a stable atomization efficiency.

[0074] It should be noted that the diameter range of the water absorbing strip 20 and the length range of the water outlet channel 12 are only exemplified in this embodiment, but are not exhaustive. In the actual manufacturing process, water absorbing strips 20 of other sizes can be selected or water outlet channels 12 of other sizes can be set according to production requirements. In other implementations of this embodiment, as long as the diameter of the cross section of the water absorbing strip 20 is smaller than the length of the water outlet channel 12, the water absorbing strip 20 in the water outlet channel 12 can be constrained to achieve the effect of maintaining a straight line arrangement, as an equivalent replacement of the concept of the present invention, it should also be within the scope of protection of this application.

[0075] Specifically, as another implementation of this embodiment, a fixing seat 15 is protrudingly provided on the outer wall of the box body 10, and the fixing seat 15 is hollow to form the water outlet channel 12; an installation groove 151 is formed on the end surface of the fixing seat 15 facing away from the box body 10, and the installation groove 151 is used to assemble the ultrasonic atomization assembly 30.

[0076] The fixing seat 15 disclosed in this embodiment can be integrally formed with the box body 10 . The fixing seat 15 is protrudingly arranged to facilitate the assembly of the ultrasonic atomization assembly 30 . The installation groove 151 can quickly position and constrain the ultrasonic atomization assembly 30 , which is beneficial to improving the stability of the ultrasonic atomization assembly 30 .

[0077] Specifically, the ultrasonic atomization assembly 30 disclosed in this embodiment can be connected to the fixing seat 15 by welding, bonding, clamping, interference fit, etc. to maintain stability.

[0078] like Figure 2 , Figure 3 and Figure 4 As shown, as another implementation of this embodiment, it is disclosed that a plurality of latching protrusions 152 are arranged in a ring shape on the side wall of the fixing seat 15; the vertical angle atomizing water tank device also includes an end cover 70, which is connected to the latching protrusions 152 and covered on the fixing seat 15 to cover the ultrasonic atomizing assembly 30 in the mounting groove 151.

[0079] In this embodiment, the end cap 70 is connected to the fixing seat 15, which is convenient and quick to operate and easy to assemble; there are many connection points and the connection stability is high. In addition, the end cap 70 is used to support the ultrasonic atomization component 30, which improves the stability of the ultrasonic atomization component 30; it can also shield the ultrasonic atomization component 30 and protect the ultrasonic atomization component 30. Specifically, in this embodiment, the shape of the end cap 70 is annular, and the center is hollowed out to facilitate the spraying of the atomized liquid.

[0080] For example Figure 2 As shown, as another implementation of this embodiment, the ultrasonic atomization assembly 30 is disclosed to include an oscillating mesh plate 31 and a rubber sleeve 32 arranged to wrap the edge of the oscillating mesh plate 31, one side of the rubber sleeve 32 is in contact with the box body 10, and the other side is in contact with the end cover 70; the depth value of the mounting groove 151 is less than or equal to the thickness of the rubber sleeve 32.

[0081] In this embodiment, the ultrasonic atomization assembly 30 converts electrical signals into ultrasonic signals through piezoelectric ceramics when working, so that the oscillating mesh sheet 31 vibrates to pump liquid. The rubber sleeve 32 plays a buffering role, protects the oscillating mesh sheet 31, and reduces the collision between the oscillating mesh sheet 31 and the fixing seat 15 and the end cover 70. The rubber sleeve 32 can be made of silicone, latex, etc., and has a certain elasticity. The depth value of the mounting groove 151 is less than or equal to the thickness of the rubber sleeve 32. When the end cover 70 is covered on the rubber sleeve 32, the two sides of the rubber sleeve 32 are respectively in contact with the end cover 70 and the fixing seat 15, which plays a sealing effect, thereby avoiding liquid leakage at the fixing seat 15.

[0082] Specifically, as another implementation of this embodiment, a glue layer is disclosed to be filled between the side wall of the rubber sleeve 32 and the side wall of the mounting groove 151. In this embodiment, the glue layer is formed by glue dispensing to further improve the sealing and stability, so that the ultrasonic atomization assembly 30 is connected to the fixing seat 15 as a whole, which is conducive to long-term use and improves stability.

[0083] like Figure 3 , Figure 4 and Figure 5As shown, as another implementation of this embodiment, it is disclosed that the box body 10 is a transparent or translucent box body 10; a holder 16 is provided on the outer wall of the box body 10; the vertical angle atomizing water tank device also includes a water level observation light 80, and the water level observation light 80 is arranged on the holder 16.

[0084] The vertical angle atomizing water tank device disclosed in this embodiment is used on a satellite simulation platform and can be used repeatedly and tested multiple times. During each use, the water level observation lamp 80 can be turned on to illuminate the water storage chamber 11, so as to facilitate observation of the water level in the box body 10 and timely replenish water when water is lacking. The water level observation lamp 80 can be powered by an external power supply, or it can be used as a power source with a dry cell or a lithium battery. Preferably, the water level observation lamp 80 can be connected to the control panel 60 and automatically controlled by the control panel 60.

[0085] like Figure 6 As shown, as another embodiment of the present application, a control method of a vertical angle atomizing water tank device is disclosed, which is used for any vertical angle atomizing water tank device as described above; wherein the control method comprises:

[0086] S100, starting the ultrasonic atomization component 30 based on the simulation signal;

[0087] S200, collecting the reading of the humidity sensor 50 to obtain real-time humidity data;

[0088] S300, if the real-time humidity data is less than a preset humidity threshold, generating a shutdown signal;

[0089] S400, stopping the ultrasonic atomization assembly 30 based on the shutdown signal.

[0090] The vertical angle atomizing water tank device disclosed in the present embodiment is used as a propeller of a satellite simulation platform to control the propulsion action of the simulated satellite. The simulation signal is the simulation data generated by the satellite simulation platform to simulate the propulsion, change of orbit and other instructions of the satellite. When the control board 60 receives the simulation signal, the ultrasonic atomizing assembly 30 is started to atomize with a characteristic ultrasonic frequency. During the atomization process, the humidity sensor 50 is turned on to continuously detect the humidity in the beam tube 40. When the atomization work is carried out normally, the humidity in the beam tube 40 is high, and if there is a lack of water in the box 10, the atomization effect decreases, and the humidity will decrease. Therefore, when the real-time humidity data rains and presets the humidity threshold, it means that the amount of liquid in the water absorbing strip 20 is reduced. Since the end of the water absorbing strip 20 extends to the bottom of the water storage chamber 11, it is indirectly explained that there is a lack of water in the box 10, and the simulation display cannot be continued, so the ultrasonic atomizing assembly 30 is stopped.

[0091] It can be seen that this embodiment can accurately control the test process of the vertical angle atomization water tank device by detecting real-time humidity data, protect the ultrasonic atomization component 30, remind the operator to replenish water in the box 10, and maintain the high simulation degree of the satellite simulation platform.

[0092] Specifically, the preset humidity threshold in this embodiment is set according to the test needs. Generally, when the relative humidity in the beam tube 40 is lower than 70%, it means that the atomization effect is weak and the thrust of the injection is insufficient. It should be noted that in actual operation, the preset humidity threshold can be set between 50% and 90% according to actual conditions. This embodiment only exemplifies the value range of the preset humidity threshold, not an exhaustive list.

[0093] Specifically, as an implementation of this embodiment, the step of generating the simulation signal includes:

[0094] Q100, determining a simulation mode; wherein the simulation mode includes direct injection and spot injection;

[0095] Q200, determining an injection cycle based on the simulation mode;

[0096] Q300. Generate a simulation signal based on the injection cycle.

[0097] In this embodiment, multiple modes are set to adjust the propulsion method during the atomization process, thereby further controlling the atomization amount and providing high control flexibility, so that the propulsion and orbit change operations of the satellite simulation platform are closer to the operating mode of the on-orbit satellite, thereby improving the degree of simulation.

[0098] It should be understood that the various parts of the present application can be implemented in hardware, software, firmware or a combination thereof.

The above-mentioned integrated module may be implemented in the form of hardware or in the form of a software functional module.
