[0075] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0076] In order to facilitate understanding of the technical solutions and technical effects of the embodiments of the present application, the related technologies of the present application will be briefly described below.

[0077] A global navigation satellite system (GNSS) is a system that uses navigation signals for positioning, navigation and timing. Specifically, the global navigation satellite system includes a GNSS receiver; the GNSS receiver is a receiving device of the global navigation satellite system, which can receive signals, i.e., GNSS signals, emitted by the global navigation satellite system. By processing these signals, the GNSS receiver can determine its precise position, movement speed and time. If the GNSS receiver is installed on a device in the fields of aviation, navigation, etc., the position, movement speed and time of the device can be determined. Therefore, the GNSS receiver has become an indispensable navigation device in the fields of aviation, navigation, etc.

[0078] The GNSS receiver installed on a ship can be referred to as a shipborne GNSS receiver. The shipborne GNSS receiver can receive GNSS signals and use these signals to determine the precise position, sailing speed and current time of the ship. However, the working environment of the shipborne GNSS receiver is complex, which can affect the actual application capability of the GNSS receiver. For example, compared with a ground-based GNSS receiver and a spaceborne GNSS receiver, the shipborne GNSS receiver is greatly affected by the sway of the ship body in the working scene. On the sea, the ship will sway due to the influence of the sea waves, which will cause the antenna of the shipborne GNSS receiver to change its orientation constantly, thereby affecting the quality and quantity of the GNSS signals received by the shipborne GNSS receiver. There can be masts, chimney structures around the shipborne GNSS receiver, which can become shielding factors and interfere with the application of the shipborne GNSS receiver. In addition, during the propagation of the GNSS signals, the GNSS signals can be reflected by the sea surface, thereby producing a multipath effect, causing the receiver to receive the superposition of the direct signal and the reflected signal, and interfering with the positioning of the shipborne GNSS receiver.

[0079] Due to the complex working environment of the shipborne GNSS receiver, it is difficult to test the shipborne GNSS receiver in the related art and obtain the application capability of the shipborne GNSS receiver in the corresponding complex working environment.

[0080] Reference Figure 1, and a structure block diagram of a shipborne signal receiver test system provided in an embodiment of the present application is shown, the shipborne signal receiver test system comprising: a shipborne signal receiver, a signal simulator, a three-axis turntable and a data processing and control server; the shipborne signal receiver comprising a positioning antenna, and the positioning antenna is installed on the three-axis turntable; the data processing and control server is in communication connection with the shipborne signal receiver;

[0081] The signal simulator is configured to generate an analog signal corresponding to the shipborne signal receiver; the analog signal corresponding to the shipborne signal receiver is a signal received by the shipborne signal receiver when the shipborne signal receiver is installed on a preset ship, and the ship is located on a preset sea surface;

[0082] The three-axis turntable is configured to generate analog rocking state information of the ship on the sea surface, and rock and / or keep a static state based on the analog rocking state information, so that the positioning antenna is in a rocking state and / or a static state;

[0083] The positioning antenna is configured to obtain a to-be-processed signal by attempting to receive the analog signal; in the case that the positioning antenna is in a rocking state and a static state, the to-be-processed signal obtained by the positioning antenna is a test signal and a standard signal respectively;

[0084] The shipborne signal receiver is configured to receive the test signal and the standard signal obtained by the positioning antenna, and send the test signal and the standard signal to the data processing and control server;

[0085] The data processing and control server is configured to obtain a first signal receiving capability of the shipborne signal receiver in the case that the positioning antenna is in a rocking state by comparing the test signal and the standard signal.

[0086] In the embodiment of the present application, the shipborne signal receiver can be a shipborne GNSS receiver. The shipborne GNSS receiver is installed on a ship, can receive GNSS signals, and utilizes the signals to determine the accurate position, navigation speed and current time of the ship.

[0087] In the embodiment of the present application, the shipborne signal receiver can be a shipborne GNSS receiver. The shipborne GNSS receiver is installed on a ship, can receive GNSS signals, and utilizes the signals to determine the accurate position, navigation speed and current time of the ship.

[0088] In the embodiment of the present application, the test system of the ship-borne signal receiver can include a ship-borne signal receiver, a signal simulator and a three-axis turntable. The ship-borne signal receiver can be a ship-borne GNSS receiver, and the signal simulator can be a GNSS simulator. The ship-borne GNSS receiver includes a positioning antenna, which can be detached from the ship-borne GNSS receiver and installed on the three-axis turntable, and the positioning antenna and the ship-borne GNSS receiver can be connected through a radio frequency cable.

[0089] In the embodiment of the present application, the signal simulator can generate a simulated signal corresponding to the ship-borne signal receiver. Specifically, the simulated signal simulates the signal received by the ship-borne signal receiver when the ship-borne signal receiver attempts to receive the GNSS signal sent by the global navigation satellite system under the condition that the ship-borne signal receiver is installed on a ship and the ship is on the sea surface. The simulated signal is the signal received by the ship-borne signal receiver under the action of at least one of the shielding of the mast, the smokestack and other structures around the ship-borne GNSS receiver, ionospheric scintillation and the reflection of the GNSS signal on the sea surface during the propagation process.

[0090] In the embodiment of the present application, the three-axis turntable can generate simulated rocking state information of the ship on the sea surface and rock based on the simulated rocking state information to simulate the rocking of the ship-borne GNSS receiver on the sea surface. In addition, the three-axis turntable can also remain in a stationary state.

[0091] Since the positioning antenna of the ship-borne signal receiver is installed on the three-axis turntable, the three-axis turntable can rock and / or remain in a stationary state based on the simulated rocking state information, so that the positioning antenna is in a rocking state and / or a stationary state.

[0092] In the embodiment of the present application, the positioning antenna can receive the to-be-processed signal by attempting to receive the simulated signal generated by the signal simulator. In the case that the positioning antenna is in a rocking state and a stationary state, the to-be-processed signal obtained by the positioning antenna is a test signal and a standard signal, respectively.

[0093] In the embodiment of the present application, the positioning antenna and the ship-borne signal receiver are connected through a radio frequency cable, and the positioning antenna can send the received standard signal and test signal to the ship-borne signal receiver.

[0094] The test system of the ship-borne signal receiver also includes a data processing and control server. The data processing and control server is in communication connection with the ship-borne signal receiver. The ship-borne signal receiver can send the received standard signal and test signal, i.e. real-time data, to the data processing and control server.

[0095] In the embodiment of the present application, the data processing and control server can compare the test signal and the standard signal to obtain the first signal receiving capability of the ship-borne signal receiver when the positioning antenna is in a rocking state, i.e., the first signal receiving capability of the ship-borne signal receiver when the ship-borne signal receiver is installed on a ship, the ship is on the sea, and the ship rocks due to waves.

[0096] Specifically, the test signal value of the test signal and the standard signal value of the standard signal can be compared, the difference between the test signal value and the standard signal value is obtained, and if the difference exceeds a preset difference range, it indicates that the first signal receiving capability of the ship-borne signal receiver is poor and cannot be used normally when the ship-borne signal receiver is installed on a ship, the ship is on the sea, and the ship rocks due to waves, and the accurate position, sailing speed, and current time of the ship cannot be determined.

[0097] In some embodiments of the present application, the test system further comprises a repeater antenna; the repeater antenna is in communication connection with the signal simulator; the repeater antenna is in a stationary state; the phase centers of the positioning antenna and the repeater antenna are consistent when the positioning antenna is in a stationary state;

[0098] The repeater antenna is configured to send the analog signal.

[0099] In the embodiment of the present application, the test system of the ship-borne signal receiver further comprises a repeater antenna, and the repeater antenna is in communication connection with the signal simulator. The analog signal generated by the signal simulator, which can also be referred to as a positioning signal, is used for positioning a ship on the sea. In the embodiment of the present application, the signal simulator can send the generated signal to the repeater antenna. The repeater antenna can send the analog signal. The positioning antenna of the ship-borne signal receiver can try to receive the positioning signal.

[0100] In the embodiment of the present application, the repeater antenna is always in a stationary state. When the positioning antenna of the ship-borne signal receiver is in a stationary state, the phase centers of the positioning antenna and the repeater antenna are consistent. Therefore, the positioning antenna obtains the standard signal as the signal to be processed when the positioning antenna is in a stationary state. When the standard signal is used for positioning the ship, the positioning accuracy is high.

[0101] In some embodiments of the present application, the test system further comprises a human-computer interaction device; the human-computer interaction device is in communication connection with the data processing and control server;

[0102] The human-computer interaction device is configured to send the analog information input by a user to the data processing and control server, and the analog information comprises at least one of an initial signal, signal flicker information, sea state information of the sea, position information and travel trajectory information of the ship on the sea.

[0103] The data processing and control server is configured to generate simulator control instructions based on at least one of the initial signal, the signal flicker information, the position information and the trajectory information of the ship on the sea surface, and to generate a turntable control instruction based on the sea state information.

[0104] In the embodiment of the application, the test system of the ship-borne signal receiver further comprises a human-computer interaction device, which is in communication connection with the data processing and control server. The data processing and control server and the human-computer interaction device can constitute a data analysis and control system, which is mainly responsible for receiving and processing data received by the ship-borne signal receiver in real time.

[0105] The user can input simulation information through the human-computer interaction device. The simulation information includes at least one of the initial signal, the signal flicker information, the sea state information of the sea surface, the position information and the trajectory information of the ship on the sea surface. The simulation information is equivalent to the test scheme for the ship-borne signal receiver input by the user through the human-computer interaction device.

[0106] In response to the simulation information input by the user, the human-computer interaction device can send the simulation information to the data processing and control server. The data processing and control server can generate simulator control instructions based on at least one of the initial signal, the signal flicker information, the position information and the trajectory information of the ship on the sea surface.

[0107] The initial signal can be a GNSS signal emitted by a GNSS. The signal flicker information represents information about possible signal flicker and fluctuation in the process of propagation of the GNSS signal under the shielding effect of a possible mast, chimney structure around the ship-borne GNSS receiver and / or ionospheric scintillation. The ionospheric scintillation refers to irregular changes in the ionosphere, which can affect the propagation of the GNSS signal and cause changes in signal strength and phase.

[0108] The simulator control instruction is used to control the signal simulator to generate a corresponding carrier simulation track according to the position information and the track information of the ship on the sea surface. The carrier simulation track represents a simulation moving track of the ship on the sea surface. Further, the signal simulator can generate a simulation signal converted from the initial signal under the action of at least one of ionospheric scintillation, a mast or a chimney structure around the ship-borne GNSS receiver, and sea surface reflection of the GNSS signal in the propagation process based on the initial signal, the signal scintillation information, and the carrier simulation track. The simulation signal is also associated with the carrier simulation track, and the change of the simulation signal is synchronized with the specific position and motion state of the carrier on the carrier simulation track in time and space. Moreover, the characteristics (such as signal strength, phase, multipath effect, etc.) of the simulation signal are simulated according to the position and motion state of the carrier on the simulation track, which includes the comprehensive action of ionospheric scintillation, the influence of the shelter, and sea surface reflection.

[0109] In the embodiment of the application, the data processing and control server can also generate the turntable control instruction based on the sea state information of the sea surface input by the user. The turntable control instruction can control the three-axis turntable to simulate the rocking state of the ship on the sea surface under the action of the sea wave.

[0110] In some embodiments of the application, the simulation signal is a signal received by the ship-borne signal receiver when the ship-borne signal receiver attempts to receive the initial signal.

[0111] The data processing and control server is configured to obtain the second signal receiving capability of the ship-borne signal receiver on the sea surface by comparing the initial signal and the standard signal.

[0112] In the embodiment of the application, the simulation signal generated by the signal simulator is a signal received by the ship-borne signal receiver when the ship-borne signal receiver attempts to receive the initial signal sent by the global navigation satellite system under the condition that the ship-borne signal receiver is installed on the ship and the ship is on the sea surface.

[0113] The signal simulator can send the simulation signal to the repeater antenna, and the repeater antenna can send the simulation signal. The signal simulator and the repeater antenna constitute a signal generation system. The positioning antenna in the static state attempts to receive the simulation signal, and the received signal is a standard signal. The positioning antenna can send the standard signal to the data processing and control server, and the data processing and control server can obtain the second signal receiving capability of the ship-borne signal receiver on the sea surface by comparing the standard signal and the initial signal, i.e., the second signal receiving capability of the ship-borne signal receiver to the initial signal sent by the global navigation satellite system under the condition that the ship-borne signal receiver is installed on the ship, the ship is on the sea surface, and the initial signal sent by the global navigation satellite system is affected by at least one of the mast and the chimney, sea surface reflection, and ionospheric scintillation.

[0114] Specifically, the initial signal value of the initial signal and the standard signal value of the standard signal can be compared, the difference between the initial signal value and the standard signal value is obtained, and if the difference exceeds a preset difference range, it indicates that the ship-borne signal receiver is installed on the ship, the ship is on the sea surface, and the initial signal sent by the global navigation satellite system is affected by at least one of the sheltering of the mast and the chimney, the sea surface reflection, and the ionospheric scintillation, so that the second signal receiving capability of the ship-borne signal receiver for the initial signal is poor, and the ship-borne signal receiver cannot be normally used and cannot determine the accurate position, the sailing speed, and the current time of the ship.

[0115] In some embodiments of the present application, the signal simulator is configured to receive the simulator control instruction sent by the data processing and control server, and generate the simulation signal based on the simulator control instruction.

The user can continuously change the input according to the navigation requirement through the man-machine interface to simulate the complex sea state. The static state of the three-axis turntable is defined as the standard state, which is used as the reference value for the subsequent test. When the three-axis turntable is in the static state, the signal received by the positioning antenna is the standard signal.

The three-axis turntable is used to generate the simulated swing state information of the ship on the sea surface, and swing and / or keep the static state based on the simulated swing state information, so that the positioning antenna is in the swing state and / or the static state. The positioning antenna is used to obtain the to-be-processed signal by attempting to receive the simulated signal. In the case that the positioning antenna is in the swing state and the static state, the to-be-processed signal obtained by the positioning antenna is the test signal and the standard signal respectively. The ship-borne signal receiver is used to receive the test signal and the standard signal obtained by the positioning antenna, and send the test signal and the standard signal to the data processing and control server. The data processing and control server is used to obtain the first signal receiving capability of the ship-borne signal receiver in the swing state of the positioning antenna by comparing the test signal and the standard signal. In the embodiment of the present application, the simulated signal related to the carrier simulation track is obtained by generating the simulated signal through the signal simulator, and the swing state of the ship in the sea navigation state is simulated by the three-axis turntable to receive the simulated signal, so as to realize the simulation test of the ship-borne signal receiver under the approximate real ship-borne condition, which can effectively improve the development efficiency of the ship-borne signal receiver, improve the environmental adaptability of the ship-borne signal receiver, test the extreme application environment requirement of the ship-borne signal receiver, and improve the practical application capability of the ship-borne signal receiver.
