[0047] Satellites are transported to space by carrier rockets. Before the launch of the carrier rocket, the status of the carrier rocket and the satellite need to be tested. The communication between carrier rockets and satellites and the ground is wireless link communication. There are many wireless system products installed on rockets and satellites. Rockets are divided into telemetry receiving equipment, external measurement transceiver equipment, and external security receiving equipment. Satellites are divided into telemetry transmitting equipment and remote control receiving equipment. There are many corresponding rocket and satellite ground test equipment. Traditional telemetry ground stations are divided into rocket telemetry ground equipment and satellite telemetry ground equipment. The carrier rocket and satellite are tested separately, resulting in the overall large size and heavy weight of the telemetry ground station, and the test operation is cumbersome. Among them, the rocket telemetry ground equipment and the satellite telemetry ground equipment are designed with multiple cabinets. The frequency conversion function and signal processing function are all designed as independent plug-in boxes, and are equipped with special detection instruments such as spectrum analyzers and oscilloscopes. The overall size is large and the weight is heavy.

[0048] In order to solve the above technical problems, this embodiment provides a launch vehicle integrated ground test system, such as Figures 1 to 7As shown, the integrated ground test system of the launch vehicle includes an antenna module and a ground host device, and the ground host device includes a power module, and a radio frequency module, a baseband signal processing module and a data processing module connected in communication. Among them, the power module is used to convert the external power supply into an input voltage, and supply power to the radio frequency module, the baseband signal processing module, and the data processing module, that is, to convert the external power supply voltage into the working voltage of each module respectively, so that each module can work normally. The power supply of each module is concentrated through a power module, which is conducive to saving volume and weight. The baseband signal processing module is used to generate an uplink test signal, and the radio frequency module is used to receive the uplink test signal, and transmit the uplink test signal to the launch vehicle signal transceiver and the satellite signal transceiver through the antenna module after up-conversion processing; the radio frequency module is also used to receive the downlink test signal transmitted by the launch vehicle signal transceiver and the satellite signal transceiver through the antenna module, and send the downlink test signal to the baseband signal processing module after down-conversion processing, and the baseband signal processing module is also used to demodulate the downlink test signal, and send the demodulated test data to the data processing module, and the data processing module is used to parse the test data and interpret the data according to the parsing result. When testing the pre-launch functions of a launch vehicle carrying a satellite, signal transmission and real-time analysis are achieved through the integrated baseband signal processing module, RF module, antenna module, and data processing module, thereby realizing synchronous testing of the pre-launch functions of the launch vehicle and satellite, simplifying the test operation, and the judgment results obtained through real-time analysis during the test can be used as a real-time judgment basis for subsequent launch control.

[0049] Among them, the launch vehicle is equipped with an onboard transmitter, an external test receiver, a safety and control receiver and a satellite, and the satellite is equipped with an onboard receiver and an onboard transmitter; the uplink test signal includes an uplink pulse signal, a safety and control signal and a satellite uplink signal, and the downlink test signal includes a downlink pulse signal, a space-based radio frequency signal, a ground-based radio frequency signal and a satellite downlink signal. The baseband signal processing module generates an uplink pulse signal and a security control signal, which are up-converted by the RF module and transmitted to the external test transceiver and the security control receiver via the antenna module respectively. The RF module also receives the space-based RF signal and the ground-based RF signal transmitted from the space-based terminal and the ground-based terminal, i.e., the onboard transmitter, and the downlink pulse signal transmitted from the external test transceiver via the antenna module, and then adjusts, analyzes and interprets them through the baseband signal processing module and the data processing module, thereby realizing the functional test of the launch vehicle by the ground host equipment, such as obtaining the status information of the launch vehicle; the baseband signal processing module also generates a satellite uplink signal, which is up-converted by the RF module and transmitted to the onboard receiver via the antenna module. The onboard receiver transmits a satellite downlink signal, and the RF module receives the satellite downlink signal through the antenna module, and adjusts, analyzes and interprets them through the baseband signal processing module and the data processing module, thereby realizing the functional test of the satellite by the ground host equipment, such as obtaining the status information of the satellite.

[0050] Specifically, Figure 1 and Figure 2 As shown, the RF module includes multiple RF transceivers, namely the first RF transceiver, the second RF transceiver, the third RF transceiver, the fourth RF transceiver, the fifth RF transceiver and the sixth RF transceiver, and the antenna module includes a ground-based receiving antenna, a space-based receiving antenna, a security control transmitting antenna, an external measurement transceiver antenna, a satellite receiving antenna and a satellite transmitting antenna. The specific functions of each RF transceiver are as follows:

[0051] The first RF transceiver is used to receive the ground-based RF signal transmitted by the carrier rocket signal transceiver, i.e., the onboard transmitter, through the ground-based receiving antenna, and send the ground-based RF signal to the baseband signal processing module after down-conversion processing; the second RF transceiver is used to receive the space-based RF signal transmitted by the carrier rocket signal transceiver, i.e., the onboard transmitter, through the space-based receiving antenna, and send the space-based RF signal to the baseband signal processing module after down-conversion processing. The ground host device receives the telemetry signal of the carrier rocket through the first RF transceiver and the second RF transceiver to obtain the status data of the carrier rocket, such as the working voltage and current information on the rocket, and the environmental parameters, etc., wherein the environmental parameters include vibration parameters, engine pressure parameters, and temperature parameters.

[0052] The third RF transceiver is used to receive the security control signal generated by the baseband signal processing module, and after up-conversion processing of the security control signal, transmit it to the carrier rocket signal transceiver, i.e., the security control receiver, through the security control transmitting antenna. The security control signal is generated by the baseband signal processing module to simulate the RF signal transmitted by the ground radar to the carrier rocket to carry out the security control self-destruction command. After receiving the security control signal, the security control receiver feeds back the state parameters to the carrier rocket. The state parameters are obtained by the ground-based RF signal and the space-based RF signal transmitted by the onboard transmitter to the ground host device, and the data processing module parses and determines whether the state parameters are normal.

[0053] The fourth radio frequency transceiver is used to receive the uplink pulse signal generated by the baseband signal processing module, and transmit the uplink pulse signal to the carrier rocket signal transceiver, i.e., the external transceiver, through the external transceiver antenna after up-conversion processing, and to receive the downlink pulse signal transmitted by the carrier rocket signal transceiver, i.e., the external transceiver, through the external transceiver antenna, and transmit the downlink pulse signal to the baseband signal processing module after down-conversion processing. The baseband signal processing module generates an uplink pulse signal to simulate the radio frequency signal of the external ballistic measurement system. The uplink pulse signal is transmitted to the external transceiver through the external transceiver antenna after up-conversion processing by the radio frequency module. The carrier rocket receives the signal and performs detection processing on the signal, and then transmits the downlink pulse signal through the external transceiver. The radio frequency module receives the downlink pulse signal through the external transceiver antenna, and transmits it to the baseband signal processing module for demodulation processing after down-conversion processing. The baseband signal processing module sends the test data obtained after demodulation to the data processing module, and the data processing module performs data analysis and interpretation. Among them, the exterior ballistic measurement system includes the GPS exterior ballistic system and the radar exterior measurement system, which uses ground-based optical and radio equipment and the GPS receiver installed on the launch vehicle to track the launch vehicle and measure the position and speed-related information of the launch vehicle to predict the predetermined orbit.

[0054] The fifth RF transceiver is used to receive the satellite downlink signal transmitted by the satellite signal transceiver, i.e., the onboard transmitter, through the satellite receiving antenna, and send the satellite downlink signal to the baseband signal processing module after down-conversion processing. That is, the ground host device acquires the satellite status data, wherein the satellite status data includes the satellite's onboard operating voltage, current, battery remaining information, satellite orbit, position, and environmental parameters. The acquired satellite status data facilitates the judgment of whether the satellite status is normal or not, so as to provide a basis for whether to transmit or not.

[0055] The sixth RF transceiver is used to receive the satellite uplink signal generated by the baseband signal processing module, and transmit the satellite uplink signal to the satellite signal transceiver, i.e., the onboard receiver, through the satellite transmitting antenna after up-conversion processing. The RF signal, i.e., the satellite uplink signal, transmitted by the ground satellite control system is simulated through the baseband signal processing module to simulate the ground satellite control system sending control instructions to the satellite, such as instructions to control the movement, attitude, orbit, and action of the satellite; after the onboard receiver receives the satellite uplink signal, the satellite performs RF signal analysis and processing, and then transmits the satellite downlink signal through the onboard transmitter, and the ground host equipment obtains the satellite's attitude, orbit, power system, power system and other related parameter data and interprets them to test whether the satellite signal reception function is normal.

[0056] More specifically, the baseband signal processing module includes a system-level package chip, which integrates the functions of a signal generator and a signal demodulator. The first RF transceiver, the second RF transceiver, the third RF transceiver, the fourth RF transceiver, the fifth RF transceiver and the sixth RF transceiver are all connected to the system-level package chip, and the system-level package chip is connected to the data processing module. In this embodiment, the data processing module is a computer motherboard; the system-level package chip is used to generate pulse uplink signals, security control signals and satellite uplink signals, and is also used to receive and demodulate ground-based RF signals, space-based RF signals, pulse downlink signals and satellite downlink signals, and is used to send demodulated ground-based telemetry data, space-based telemetry data, external measurement data and satellite telemetry data to the data processing module. The system-level package chip uniformly processes the above-mentioned various signals, realizes the simultaneous testing and status acquisition of the launch vehicle status and satellite functions, and greatly reduces the volume and weight of the integrated ground test system of the launch vehicle.

[0057] Preferably, the integrated ground test system for the launch vehicle further includes a network module, and the data processing module sends the data interpretation result to the external control system through the network module, for example, through Ethernet, that is, the computer mainboard is connected to the external network port through the network interface module. The external control system is used to control whether the launch vehicle is launched or not, and the external control system decides whether the launch vehicle is launched or not based on the data interpretation result.

[0058] In this embodiment, the integrated ground test system for launch vehicles is relatively small in size and can be installed on a launch device. It can communicate through a network module without the need for personnel on duty and can realize remote network control operations. The launch device refers to ground support equipment for launching launch vehicles, such as launch vehicles, launch towers, launch ships, etc.

[0059] Furthermore, if Figure 3As shown, the ground host device also has embedded software, including device embedded software, device parameter configuration software and data processing software. The device embedded software completes the reception and transmission of RF signals according to the configuration parameters set by the device parameter configuration software. When the ground host device receives the RF signal, the device embedded software completes the filtering, down-conversion and data demodulation of the RF signal according to the configuration parameters. After the data processing module analyzes and interprets, it sends the interpretation result to the external control system through the network module; the device embedded software also completes the modulation and up-conversion of the RF signal according to the configuration parameters, and radiates the uplink test signal to space through the antenna module for the signal reception of the launch vehicle signal transceiver. The device parameter configuration software is the software running in the ground host device. The device embedded software demodulates the received downlink test signal according to the configured RF signal reception frequency, bandwidth, code type, information rate, decoding method and other related RF signal parameters. The data processing software is the software running in the ground host device, which is used to process the received ground-based telemetry data, space-based telemetry data, external measurement data and satellite telemetry data, and analyze and process the data according to the specified format.

[0060] like Figure 4 As shown, after receiving the test data, the data processing software performs data analysis. When the test process starts, the data interpretation begins. For example, parameter 1 is the working voltage information on the arrow, parameter 2 is the working current information on the arrow, parameter 3 is the environmental parameter information on the arrow, parameter 5 is the working voltage information on the satellite, parameter 6 is the working current on the satellite, parameter 7 is the remaining battery information on the satellite, parameter 8 is the satellite orbit information on the satellite, parameter 9 is the working position information on the satellite, etc., to determine whether each parameter of the n parameters is within the specified range, and send the interpretation result to the external control system through the network module. The external control system determines whether the rocket and satellite are launched normally. If the data interpretation is normal, it can be launched normally. If the interpretation is wrong, it will not be launched normally. Among them, the external control system can also control the start or stop of the data processing software test through the network module to realize remote testing and improve the convenience of operation.

[0061] Furthermore, the ground host device also includes a storage module, which is electrically connected to the power module and is in communication connection with the RF module and the baseband signal processing module. The power module is also used to supply power to the storage module, and the storage module is used to store the downlink test signal received by the RF module and the test data parsed by the data processing module. Preferably, the ground host device also includes a clock module. When the ground host device receives the downlink test signal, the storage module automatically performs the data storage function according to the default data storage location, and the clock module adds a time code to the data stored in the storage module according to the local time, which is used as the time basis for subsequent data reading.

[0062] In this embodiment, the baseband signal processing module is also used to obtain the stored historical downlink test signal from the storage module, and send the demodulated historical downlink test signal to the data processing module, which analyzes and interprets the signal and sends the interpretation result to the external control system through the network module. This verifies whether the network connection status of the ground host device is normal, and verifies whether the data parsing function of the ground host device is normal.

[0063] like Figures 5 to 7 As shown, preferably, the ground host device further includes a self-test module, the self-test module includes a radio frequency gating switch, and the radio frequency gating switch is used to select the receiving source of the receiving end of the radio frequency module and the transmitting source of the transmitting end as a self-closed loop radio frequency signal, so as to detect whether the receiving channel and the transmitting channel of the ground host device are normal or not, as follows:

[0064] Detection of the receiving channel of the ground host device: The baseband signal processing module is also used to obtain historical test data from the storage module, and send the test analog signal generated by modulating and encoding the historical test data to the RF module. The RF module performs up-conversion and down-conversion processing on the test analog signal and sends it to the baseband signal processing module. The baseband signal processing module demodulates, decodes, frames and synchronizes the test analog signal to obtain analog data, and transmits the analog data to the data processing module. The data processing module compares the historical test data and the analog data, and stores the data at the same time to determine whether the receiving channel of the ground host device is normal. It should be noted that when the baseband signal processing module obtains historical test data from the storage module and sends the test analog signal generated by modulating and encoding the historical test data to the RF module, different test analog signals are generated according to the different detection channels required, such as simulating the generation of space-based RF signals, ground-based RF signals, downlink pulse signals and satellite downlink pulse signals. That is, the detection of the receiving channel of the ground host equipment includes the self-closed loop detection of the receiving channel of the ground-based radio frequency signal, the self-closed loop detection of the receiving channel of the space-based radio frequency signal, the self-closed loop detection of the receiving channel of the downlink pulse signal, and the self-closed loop detection of the receiving channel of the satellite downlink signal.

[0065] Detection of the transmission channel of the ground host equipment: The baseband signal processing module is used to generate an uplink test signal, which is received by the RF module after mixing processing, and is sent to the baseband signal processing module after up-conversion, filtering, and down-conversion processing. The baseband signal processing module detects the uplink test signal, and the data processing module obtains the status output according to the detection result, and performs data interpretation and storage at the same time. According to the interpretation result, it can be judged whether the transmission channel of the ground host equipment is normal. It should be noted that, according to the requirements of the detection channel, the baseband signal processing module generates different uplink test signals, such as uplink external measurement signals, security control signals, uplink pulse signals, and satellite uplink pulse signals. That is, the detection of the transmission channel of the ground host equipment includes the self-closed loop detection of the transmission channel of the security control signal, the self-closed loop detection of the transmission channel of the uplink pulse signal, and the self-closed loop detection of the generation channel of the satellite uplink signal.

[0066] Before the ground host equipment tests the launch vehicle and satellite, the ground host equipment performs a self-test, that is, the BIT test begins, and the following tests are performed in sequence: computer motherboard test (including CPU, network interface connection, etc.), data processing module test, network communication status test, ground-based radio frequency signal receiving channel self-closed loop test, space-based radio frequency signal receiving channel self-closed loop test, pulse signal channel self-closed loop test (including uplink pulse signal receiving channel self-closed loop test, downlink pulse signal transmitting channel self-closed loop test), security control signal transmitting channel self-closed loop test, satellite uplink signal transmitting channel self-closed loop test, satellite downlink signal receiving channel self-closed loop test. During the above-mentioned detection process, if each detection process is successful, the next detection will be carried out. If it is unsuccessful, fault diagnosis and troubleshooting will be carried out. After the fault is eliminated, the BIT test will be restarted. If the troubleshooting is unsuccessful, the test will stop and an error will be reported. When all the tests are successful, the test is completed, that is, the ground host equipment enters normal working state.

[0067] When the self-test of the receiving channel and transmitting channel of the ground host device is completed, the embedded software in the ground host device enters the normal working mode. The signal input end of the RF module sets the receiving source to the downlink test signal received by the antenna module through the RF selection switch. The device parameter configuration software sets the signal source parameters of the received downlink test signal. The signal parameters include signal frequency, code type, information rate, decoding method, etc. When the ground host device receives the downlink test signal, the device embedded software performs down-conversion, decoding, code type conversion, frame synchronization, data packaging, data storage, data analysis, data interpretation and other operations according to the corresponding configuration parameters. Then the data processing software sends the data to the outside in packets through Ethernet.

[0068] When transmitting external measurement signals, security control signals and satellite uplink signals, the equipment parameter configuration software sets the parameters of the transmission signal source, including the transmission frequency point, output power, pulse width, pulse repetition frequency, pulse delay and other parameters of the external measurement signal; the transmission frequency point, output power, signal system, security control codeword information and other parameters of the external security signal; the transmission frequency point, output power, signal system and other parameters of the satellite uplink signal, which are used to control the status of the transmitted external measurement signals, security control signals and satellite uplink signals.

The launch vehicle integrated ground test system has simplified hardware and low cost.
