Description

Technical Field

[0001] The present invention relates to the satellite and application industry, and particularly to a satellite navigation ground monitoring enhancement control system and method. Background Art

[0002] Currently, the main satellite navigation systems are GPS of the United States, GLONASS of Russia, GALILEO of the European Union, and BDS of China. A satellite navigation system generally consists of a satellite system, a ground system, and a user system. Monitoring stations and master control stations are the main components of the ground system. The monitoring stations are responsible for collecting data and sending it to the master control station through communication satellites. After receiving the data, the master control station performs orbit determination, correction, and information calculation on the navigation satellites. The master control station can also send control commands to control the monitoring stations through communication satellites. During the process of receiving the original data signal and converting it with the ground information, the ground system is prone to interference, resulting in a reduction in ground monitoring capabilities. Eventually, the transmission of the original data lags, leading to delays or inaccurate positioning in the satellite navigation system.

[0003] Traditional monitoring enhancement methods generally implement signal enhancement for low-earth orbit satellites. An antenna controller is used to control a high-gain antenna to automatically track the signal broadcast by the satellite platform end. A beam is used to track, scan, and lock the satellite navigation enhancement signal. A filter is used to filter the satellite navigation enhancement signal and divide it into two outputs. One output is sent to a general spectrum analyzer for spectrum analysis, and the other output is connected to a radio frequency acquisition and playback device for post-processing analysis. The coverage range of traditional ground monitoring enhancement is relatively narrow, and it cannot comprehensively respond to different signal interferences. The main reasons for ground monitoring errors or delays are the interference between the monitoring stations and the master control station. In addition, the signal may become weak or the inter-station signal may be lost and weakened during the reception of the original data due to various factors. Traditional ground monitoring enhancement often ignores these factors when dealing with multiple interferences and cannot completely avoid the occurrence of the above defects by using a single technical means.

[0004] Therefore, in view of the deficiencies of the prior art, the present invention provides a satellite navigation ground monitoring enhancement control system and method with a simple structure, convenient operation, wide radiation range, capable of coping with different inter-station or monitoring station signal interference problems, improving the control ability of ground monitoring enhancement, taking diagnostic analysis for different interferences and then taking corresponding measures, with strong system stability and simple and easy-to-operate methods, and having a broad market prospect.

[0037] A satellite navigation ground monitoring and enhancement control method. When operating, navigation satellites transmit original data to monitoring stations via wireless connections. After receiving the original data, the monitoring stations perform monitoring operations on the original data through the uplink enhancement controller, and analyze whether to perform signal enhancement control on the original data. The original data after analysis and processing is uploaded to communication satellites via wireless connections through the uplink enhancement controller. The communication satellites transmit the original data uploaded by the uplink enhancement controller to the downlink enhancement controller via wireless connections. The downlink enhancement controller performs monitoring operations on the received data, analyzes whether to perform signal enhancement control on the received data, and then uploads the received data after analysis and processing to the main control station via wired connections.

[0038] The main control station transmits the received data after analysis and processing to the injection station via wired connections. After receiving the information, the injection station processes the data through the injection sending processing module to form an injection signal, and then uploads the injection signal to the injection sending analysis module for analysis. Open-circuit analysis of the injection signal connection and connection strength analysis of the injection signal are performed. When the injection signal is not open-circuited and the signal is strong, the injection signal is directly uploaded to the navigation satellite via wireless connections. When the injection signal is open-circuited or the signal is weak, the injection sending enhancement module is activated, and the injection signal is enhanced and then uploaded to the navigation satellite. The ground monitoring enhancement analysis station monitors the uplink enhancement monitor, the downlink enhancement controller, and the injection enhancement controller in real time, and selects to activate one or more of the uplink reception enhancement module, the downlink reception enhancement module, and the injection sending enhancement module according to the monitoring results.

[0039] The uplink receiving analysis module in the uplink enhancement controller first receives the raw data sent by the navigation satellite. The uplink receiving analysis module analyzes the raw data, conducts satellite signal connection interruption analysis and satellite signal connection strength analysis. When the satellite signal connection is not interrupted and the strength is strong, the data is directly transmitted to the uplink receiving processing module, and then after being processed by the uplink receiving processing module, it is transmitted to the anti-interference transmitting module through the uplink signal amplification module. Finally, the raw data is transmitted to the communication satellite through the uplink signal transmitting antenna; when the satellite signal connection is interrupted or the strength weakens, the uplink receiving enhancement module is started, and after strengthening the satellite signal, it is transmitted to the communication satellite. The downlink signal receiving antenna in the downlink enhancement controller first receives the communication signal sent by the communication satellite and transmits the communication signal to the anti-interference receiving module. The anti-interference receiving module transmits the communication signal to the downlink signal amplification module for signal amplification processing. The amplified communication signal is transmitted to the downlink receiving analysis module for analysis, conducts communication signal connection interruption analysis and communication signal connection strength analysis. When the communication signal connection is not interrupted and the strength is strong, the data is directly transmitted to the downlink receiving processing module, and then after being processed by the downlink receiving processing module, it is transmitted to the main control station; when the communication signal connection is interrupted or the strength weakens, the downlink receiving enhancement module is started, and after strengthening the communication signal, it is transmitted to the main control station.

[0040] The uplink receiving processing module mainly performs outbound digital processing operations and outbound radio frequency processing on the data from the navigation satellite. After the digital signal and radio frequency signal are processed by the uplink receiving processing module into intermediate frequency signals and converted into radio frequency signals, they are transmitted to the uplink signal amplification module. A stable wired connection is adopted among the uplink receiving analysis module, the uplink receiving enhancement module, the uplink receiving processing module, the uplink signal amplification module, the anti-interference transmitting module, and the uplink signal transmitting antenna. The downlink receiving processing module includes a digital processing part and a radio frequency processing part. After the downlink signal receiving antenna receives the radio frequency signal of the communication satellite, the interference information is filtered by the anti-interference receiving module, and then it is amplified through the downlink signal amplification and transmitted to the downlink receiving processing module for intermediate frequency signal frequency conversion operations. When the uplink receiving analysis module monitors that the data transmitted by the navigation satellite is interrupted or weakened, this monitoring information is quickly sensed by the ground monitoring enhancement analysis station through a wired connection, and the uplink receiving enhancement module is emergently started to perform enhanced receiving operations such as re-connecting the navigation satellite data or increasing the corresponding power. Similarly, when the downlink receiving analysis module monitors that the data transmitted by the communication satellite is interrupted or weakened, this monitoring information is quickly sensed by the ground monitoring enhancement analysis station through a wired connection, and the downlink receiving enhancement module is emergently started to perform enhanced receiving operations such as re-connecting the communication satellite data or increasing the corresponding power.

[0041] The communication between the monitoring station and the master control station uses PN sequence spread spectrum. First, the signal strength of the original data from the navigation satellite is monitored. When the signal strength is lower than the preset range, the uplink reception enhancement module needs to be activated. When the navigation satellite number reaches the preset range, CRC processing is performed on the original data, followed by FEC encoding. After the FEC encoding is completed, spread spectrum encoding is carried out. After the spread spectrum encoding is completed, anti-jamming transmission is performed. After locking the spread spectrum encoding, it is uploaded to the communication satellite. After the downlink signal receiving antenna receives the data transmitted by the communication satellite, anti-jamming reception is first performed on the data to filter out invalid signal sources, and the data from the locked spread spectrum encoding is received, and then despreading and defecoding operations are carried out. When the strength of the decoded data received is lower than the preset range, the downlink reception enhancement module needs to be activated. When the navigation satellite signal reaches the preset range, it is directly transmitted to the master control station.
