Description

Technical Field

[0001] This utility model relates to the field of satellite technology, and in particular to a missile-borne satellite navigation device. Background Technology

[0002] The onboard satellite navigation system is one of the most critical and important components during the use of the missile. The missile navigation system guides the missile to its destination accurately and within a predetermined route, according to the required precision.

[0003] However, existing missile-borne satellite navigation devices have a prominent problem: during use, the receiver is usually arranged separately from the antenna, which occupies too much space, while the internal space of the missile body is extremely small. In order to meet the space requirements, the antenna, low-noise amplifier, receiver and power supply are usually arranged separately during use. However, they are easily affected by the outside world during use, and they need to be connected by cables. During signal transmission, they are easily affected by the outside conditions, resulting in signal loss. In addition, the shielding effect of each module is poor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a missile-borne satellite navigation device that solves the problems of the following: during use, the receiver is usually arranged separately from the antenna, occupying too much space, while the internal space of the missile body is extremely small. In general, the antenna, low-noise amplifier, receiver, and power supply are arranged separately to meet space requirements, but they are easily affected by external factors during use and require cables to connect them. During signal transmission, they are easily affected by external conditions, resulting in signal loss. In addition, the shielding effect of each module is poor.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A missile-borne satellite navigation device includes an array antenna unit, a power supply unit, a housing, an anti-interference processing unit, a receiver unit, an external interface, and a cover plate.

[0007] Preferably, the cover plate is used to cover the array antenna unit and the anti-interference processing unit.

[0008] Preferably, a metal wall is formed between the array antenna unit, the anti-interference processing unit, and the receiver unit.

[0009] Preferably, the metal wall is used to isolate signal interference caused by the array antenna units.

[0010] Preferably, the housing cover is sealed with adhesive after installation.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] First, the anti-interference processing unit and the power supply unit are isolated by the housing, so the array antenna unit will not be affected by the electrical signal interference from the receiver unit, the anti-interference processing unit and the power supply unit, ensuring that the array antenna unit can receive the antenna signal completely. The device uses screws to fasten each module, which is convenient for disassembly and assembly and has a good electromagnetic shielding effect.

[0013] Second, there is a metal wall between the array antenna unit, the anti-interference processing unit and the receiver unit, which can isolate electrical signals and ensure that they will not cause signal interference to the array antenna unit.

[0017] This application provides an airborne satellite navigation device that effectively solves the problems of separate antenna placement, which occupies too much space, while the internal space of the missile body is extremely small. Typically, the antenna, low-noise amplifier, receiver, and power supply are placed separately to meet space requirements, but this is easily affected by external factors and requires cables for connection. Signal transmission is also susceptible to external influences, leading to signal loss. Furthermore, the shielding of each module is poor. The anti-interference processing unit and power supply unit are isolated by the housing, ensuring that the array antenna unit is not affected by electrical signal interference from the receiver unit, anti-interference processing unit, and power supply unit, thus guaranteeing complete signal reception. The device uses screws to secure each module, facilitating easy assembly and disassembly, and providing excellent electromagnetic shielding.

[0018] Example

[0019] like Figure 1 As shown, the technical solution in this application embodiment effectively solves the problems of receivers being typically separated from antennas during use, occupying too much space, while the internal space of the missile body is extremely small. Typically, the antenna, low-noise amplifier, receiver, and power supply are arranged separately to meet space requirements, but this is highly susceptible to external influences during use, requires cables for connection, and is easily affected by external conditions during signal transmission, resulting in signal loss. Furthermore, the shielding effect of each module is poor. The overall concept is as follows: A missile-borne satellite navigation device, including an array antenna unit 1 and a power supply unit 2. The shell 3, anti-interference processing unit 4, receiver unit 5, external interface 6, and cover plate 7 are reliably connected to the array antenna unit 1, power supply unit 2, anti-interference processing unit 4, receiver unit 5, external interface 6, and cover plate 7 by tightening screws. The array antenna unit 1 receives Beidou satellite signals, which are then transmitted to the anti-interference module for signal processing. After data analysis, the processed signals are transmitted to the satellite receiver, and the coordinates, altitude, and other position information of the projectile are transmitted to the projectile control module through the external interface 6, achieving the communication function between the projectile and the Beidou satellite, which plays a key role in the positioning and navigation of the projectile.

[0020] The housing 3 is fixedly connected to the outer surface of the array antenna unit 1. The power supply unit 2 is fixedly connected to the housing 3. The array antenna unit 1 is fixedly connected to the housing 3. The anti-interference processing unit 4 is fixedly connected to the housing 3. The receiver unit 5 is fixedly connected to the housing 3. The external interface 6 is opened inside the housing 3. The cover plate 7 is fixedly connected to the lower end of the housing 3. The seven parts, array antenna unit 1, power supply unit 2, housing 3, anti-interference processing unit 4, receiver unit 5, external interface 6, and cover plate 7, are fastened to each module by screws, which is convenient for disassembly and assembly and has a good electromagnetic shielding effect. There is a metal wall between the array antenna unit 1, anti-interference processing unit 4 and receiver unit 5, which can isolate electrical signals and ensure that they will not cause signal interference to the array antenna unit 1. After the housing 3 and cover plate 7 are installed, sealing them can ensure the internal sealing of the device and allow it to work normally in harsh environments.

[0021] The cover plate 7 is used to cover the array antenna unit 1 and the anti-interference processing unit 4. A metal wall is formed between the array antenna unit 1, the anti-interference processing unit 4 and the receiver unit 5. The metal wall is used to isolate the signal interference caused by the array antenna unit 1. After the housing 3 and cover plate 7 are installed, they are sealed with glue. The anti-interference processing unit 4 and the power supply unit 2 are isolated by the housing 3. The array antenna unit 1 will not be affected by the electrical signal interference from the receiver unit 5, the anti-interference processing unit 4 and the power supply unit 2, ensuring that the array antenna unit 1 can receive the antenna signal completely. The device is fastened to each module by screws, which is convenient for disassembly and assembly and has a good electromagnetic shielding effect.

[0022] To address the problems existing in the prior art, this utility model provides a missile-borne satellite navigation device. The anti-interference processing unit 4 and the power supply unit 2 are isolated by the housing 3. The array antenna unit 1 will not be affected by the electrical signal interference from the receiver unit 5, the anti-interference processing unit 4, and the power supply unit 2, ensuring that the array antenna unit 1 can completely receive the antenna signal. The device uses screws to fasten each module, which is convenient for disassembly and assembly, and has a good electromagnetic shielding effect.

[0023] Working principle:

[0024] The first step involves reliably connecting the array antenna unit 1, power supply unit 2, anti-interference processing unit 4, receiver unit 5, external interface 6, and cover plate 7 to the system by tightening screws. The array antenna unit 1 receives BeiDou satellite signals, which are then transmitted to the anti-interference module for processing. After data analysis, the processed signals are transmitted to the satellite receiver, where the projectile's coordinates, altitude, and other positional information are transmitted to the projectile control module via the external interface 6. This enables communication between the projectile and the BeiDou satellite, playing a crucial role in the projectile's positioning and navigation. The seven components—array antenna unit 1, power supply unit 2, housing 3, anti-interference processing unit 4, receiver unit 5, external interface 6, and cover plate 7—are secured with screws, facilitating easy assembly and disassembly and providing excellent electromagnetic shielding. A metal wall between the array antenna unit 1, anti-interference processing unit 4, and receiver unit 5 isolates electrical signals, preventing interference with the array antenna unit 1. Sealing the housing 3 and cover plate 7 after installation ensures the device's internal airtightness, allowing it to operate normally even in harsh environments.

[0025] In the second step, the anti-interference processing unit 4 and the power supply unit 2 are isolated by the housing 3. The array antenna unit 1 will not be affected by the electrical signal interference from the receiver unit 5, the anti-interference processing unit 4 and the power supply unit 2, ensuring that the array antenna unit 1 can receive the antenna signal completely. The device uses screws to fasten each module, which is convenient for disassembly and assembly and has a good electromagnetic shielding effect.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
