DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] To facilitate understanding of the technical solutions and technical effects of the embodiments of the present invention, the relevant technologies of the present invention are briefly described below.

[0031] The 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; a GNSS receiver is a receiving device of the Global Navigation Satellite System that can receive signals sent by the Global Navigation Satellite System, namely, GNSS signals. By processing these signals, the GNSS receiver can determine its precise position, movement speed and time. If the GNSS receiver is installed on equipment in the fields of aviation, navigation, etc., the position, movement speed and time of the equipment can be determined. Therefore, the GNSS receiver has become an indispensable navigation device in the fields of aviation, navigation, etc.

[0032] GNSS receivers installed on ships can be called shipborne GNSS receivers. Shipborne GNSS receivers 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 shipborne GNSS receivers is complex, which will affect the actual application capabilities of GNSS receivers. For example, compared with ground-based GNSS receivers and satellite-based GNSS receivers, shipborne GNSS receivers are mainly affected by the swaying of the hull in the working scene. On the sea, the ship will sway due to the influence of waves, which will cause the antenna orientation of the shipborne GNSS receiver to change continuously, thereby affecting the quality and quantity of GNSS signals received by the shipborne GNSS receiver. There may be masts and chimney structures around the shipborne GNSS receiver, which may become shielding factors and interfere with the application of the shipborne GNSS receiver. In addition, during the propagation process, the GNSS signal may be reflected by the sea surface, resulting in a multipath effect, causing the receiver to receive the superposition of direct signals and reflected signals, which interferes with the positioning of the shipborne GNSS receiver.

[0033] Due to the complex working environment of shipborne GNSS receivers, it is difficult to test shipborne GNSS receivers in related technologies and obtain the application capabilities of shipborne GNSS receivers in the corresponding complex working environment.

[0034] Reference Figure 1, shows a structural block diagram of a shipborne signal receiver test system provided in an embodiment of the present invention, 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 comprises a positioning antenna, and the positioning antenna is installed on the three-axis turntable; the data processing and control server is communicatively connected with the shipborne signal receiver; The signal simulator is used to generate a simulation signal corresponding to the shipborne signal receiver; the simulation 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; The three-axis turntable is used to generate simulated swaying state information of the vessel on the sea surface, and sway and / or keep a stationary state based on the simulated swaying state information, so that the positioning antenna is in a swaying state and / or a stationary state; The positioning antenna is used to obtain the signal to be processed by attempting to receive the analog signal; when the positioning antenna is in a swinging state and a stationary state, the signals to be processed obtained by the positioning antenna are a test signal and a standard signal respectively; The shipborne signal receiver is used to receive the test signal and the standard signal acquired 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 shipborne signal receiver when the positioning antenna is in a swinging state by comparing the test signal with the standard signal.

[0035] In the embodiment of the present invention, the shipborne signal receiver may be a shipborne GNSS receiver. The shipborne GNSS receiver is installed on the ship and can receive GNSS signals and use these signals to determine the precise position, sailing speed and current time of the ship.

[0036] In the embodiment of the present invention, the shipborne signal receiver test system can be used to test the shipborne signal receiver to determine the application capability of the shipborne signal receiver in the complex environment on the sea surface. The application capability includes positioning, navigation and timing capabilities.

[0037] In an embodiment of the present invention, a test system for a shipborne signal receiver may include a shipborne signal receiver, a signal simulator and a three-axis turntable. The shipborne signal receiver may be a shipborne GNSS receiver, and the signal simulator may be a GNSS simulator. The shipborne GNSS receiver includes a positioning antenna, which may be separated from the shipborne GNSS receiver and mounted on the three-axis turntable, and the positioning antenna and the shipborne GNSS receiver may be connected via a radio frequency cable.

[0038] In an embodiment of the present invention, a signal simulator can generate a simulation signal corresponding to a shipboard signal receiver. Specifically, the simulation signal corresponding to the shipboard signal receiver simulates: when the shipboard signal receiver is installed on a ship and the ship is on the sea, the shipboard signal receiver attempts to receive a GNSS signal sent by a global navigation satellite system, and the signal is received. The simulation signal is the signal received by the shipboard signal receiver when there is at least one of the following conditions: shielding by structures such as masts and chimneys around the shipboard GNSS receiver, ionospheric scintillation, and GNSS signals are reflected by the sea surface during propagation.

[0039] In the embodiment of the present invention, the three-axis turntable can generate simulated swaying state information of the ship on the sea surface, and sway based on the simulated swaying state information to simulate the swaying of the ship-borne GNSS receiver on the ship on the sea surface. In addition, the three-axis turntable can also remain stationary.

[0040] Since the positioning antenna of the shipborne signal receiver is installed on the three-axis turntable, the three-axis turntable can be swung and / or remain stationary based on the simulated swaying state information, so that the positioning antenna is in a swaying state and / or a stationary state.

[0041] In the embodiment of the present invention, the positioning antenna can receive the signal to be processed by trying to receive the analog signal generated by the signal simulator. When the positioning antenna is in a swinging state and a stationary state, the signals to be processed obtained by the positioning antenna are respectively a test signal and a standard signal.

[0042] In the embodiment of the present invention, the positioning antenna is connected to the shipborne signal receiver via a radio frequency cable, and the positioning antenna can send the received standard signal and test signal to the shipborne signal receiver.

[0043] The test system of the shipborne signal receiver also includes a data processing and control server. The data processing and control server is in communication connection with the shipborne signal receiver. The shipborne signal receiver can send the received standard signal and test signal, that is, real-time data, to the data processing and control server.

[0044] In an embodiment of the present invention, the data processing and control server can obtain the first signal receiving capability of the shipborne signal receiver when the positioning antenna is in a swinging state by comparing the test signal with the standard signal, that is, when the shipborne signal receiver is installed on a vessel, the vessel is on the sea, and the vessel is swinging due to waves, the first signal receiving capability of the shipborne signal receiver.

[0045] Specifically, the test signal value of the test signal and the standard signal value of the standard signal can be compared to obtain the difference between the test signal value and the standard signal value. If the difference exceeds the preset difference range, it means that when the shipborne signal receiver is installed on the vessel and the vessel is on the sea, and the vessel is swaying due to waves, the first signal receiving capability of the shipborne signal receiver is poor and cannot be used normally, and the precise position, sailing speed and current time of the vessel cannot be determined.

[0046] In some embodiments of the present invention, the test system further comprises a forwarding antenna; the forwarding antenna is communicatively connected to the signal simulator; the forwarding antenna is in a stationary state; when the positioning antenna is in a stationary state, the phase centers of the positioning antenna and the forwarding antenna are consistent; The forwarding antenna is used to send the analog signal.

[0047] In an embodiment of the present invention, the test system of the shipborne signal receiver further includes a forwarding antenna, which is communicatively connected to the signal simulator. The analog signal generated by the signal simulator may also be referred to as a positioning signal, which is used to locate the ship at sea. In an embodiment of the present invention, the signal simulator may send the generated signal to the forwarding antenna. The forwarding antenna may send out the analog signal. The positioning antenna of the shipborne signal receiver may attempt to receive the positioning signal.

[0048] In the embodiment of the present invention, the forwarding antenna is always in a stationary state. When the positioning antenna of the shipborne signal receiver is in a stationary state, the phase centers of the positioning antenna and the forwarding antenna are consistent. Therefore, when the positioning antenna is in a stationary state, the signal to be processed obtained by the positioning antenna is a standard signal. When the standard signal is used to locate the ship, the positioning accuracy is high.

[0049] In some embodiments of the present invention, the test system further comprises: a human-computer interaction device; the human-computer interaction device is communicatively connected with the data processing and control server; The human-computer interaction device is used to respond to the simulation information input by the user and send the simulation information to the data processing and control server; the simulation information includes at least one of the initial signal, signal flashing information, sea state information of the sea surface, position information of the ship on the sea surface and driving track information; The data processing and control server is used to generate simulator control instructions based on at least one of the initial signal, the signal flashing information, the position information of the ship on the sea surface and the driving trajectory information; and generate turntable control instructions based on the sea condition information.

[0050] In an embodiment of the present invention, the test system of the shipborne signal receiver further includes a human-computer interaction device, which is communicatively connected to the data processing and control server. The data processing and control server and the human-computer interaction device can form a data analysis and control system, which is mainly responsible for receiving and processing the data received by the shipborne signal receiver in real time.

[0051] The user can input simulation information through the human-computer interaction device. The simulation information includes at least one of the initial signal, signal flashing information, sea surface condition information, position information of the ship on the sea surface, and driving track information. The simulation information is equivalent to the test plan for the ship-borne signal receiver input by the user through the human-computer interaction device.

[0052] In response to the simulation information input by the user, the human-computer interaction device may send the simulation information to the data processing and control server. The data processing and control server may generate a simulator control instruction based on at least one of the initial signal, the signal flashing information, the position information of the ship on the sea surface, and the driving track information.

[0053] The initial signal may be a GNSS signal sent by the GNSS, and the information flicker information represents information about possible signal flicker and fluctuation during the propagation of the GNSS signal due to ionospheric scintillation and / or the shielding of masts and chimney structures that may exist around the shipborne GNSS receiver. Ionospheric scintillation refers to irregular changes in the ionosphere, which will affect the propagation of GNSS signals and cause changes in signal strength and phase.

[0054] The simulator control instruction is used to control the signal simulator to generate a corresponding carrier simulation trajectory according to the position information and driving trajectory information of the ship on the sea surface. The carrier simulation trajectory represents the simulated moving trajectory of the ship on the sea surface. Furthermore, the signal simulator can generate a simulated signal after the initial signal is transformed under the action of at least one of ionospheric scintillation, the obstruction of masts and chimney structures that may exist around the shipborne GNSS receiver, and the reflection of the GNSS signal by the sea surface during the propagation process based on the initial signal, signal flicker information, and carrier simulation trajectory. The simulated signal is also associated with the carrier simulation trajectory, and the change of the simulated signal is synchronized with the specific position and motion state of the carrier on the carrier simulation trajectory in time and space. Moreover, the characteristics of the simulated signal (such as signal strength, phase, multipath effect, etc.) are simulated according to the position and motion state of the carrier on the simulation trajectory, which includes the combined effect of factors such as ionospheric scintillation, obstruction, and sea surface reflection.

[0055] In an embodiment of the present invention, the data processing and control server can also generate a turntable control instruction based on the sea surface condition information input by the user. The turntable control instruction can control the three-axis turntable to simulate the swaying state of the ship under the action of waves on the sea surface.

[0056] In some embodiments of the present invention, the simulated signal is a signal received by the shipborne signal receiver by attempting to receive the initial signal; The data processing and control server is used to obtain the second signal receiving capability of the shipborne signal receiver on the sea surface by comparing the initial signal with the standard signal.

[0057] In an embodiment of the present invention, the simulation signal generated by the signal simulator is a signal received when the shipborne signal receiver is installed on a ship and the ship is on the sea and the shipborne signal receiver attempts to receive an initial signal sent by a global navigation satellite system.

[0058] The signal simulator can send a simulated signal to a forwarding antenna, and the forwarding antenna can send the simulated signal. The signal simulator and the forwarding antenna constitute a signal generation system. The positioning antenna in a stationary state attempts to receive the simulated signal, and the received signal is a standard signal. The positioning antenna can send the standard signal to a data processing and control server, and the data processing and control server can obtain the second signal receiving capability of the shipborne signal receiver on the sea surface to receive the initial signal sent by the global navigation satellite system by comparing the standard signal with the initial signal, that is, when the shipborne signal receiver is installed on a ship, the ship is on the sea surface, and the initial signal sent by the global navigation satellite system is blocked by masts and chimneys, reflected by the sea surface, and at least one of ionospheric scintillation, the shipborne signal receiver has the second signal receiving capability of the initial signal.

[0059] Specifically, the initial signal value of the initial signal and the standard signal value of the standard signal can be compared to obtain the difference between the initial signal value and the standard signal value. If the difference exceeds the preset difference range, it means that the shipborne signal receiver is installed on the ship and the ship is on the sea. The initial signal sent by the global navigation satellite system will be blocked by the mast and chimney, reflected by the sea surface and at least one of the ionospheric scintillation. The shipborne signal receiver has poor receiving capability for the second signal of the initial signal and cannot be used normally, and cannot determine the precise position, sailing speed and current time of the ship.

[0060] In some embodiments of the present invention, the signal simulator is used 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.

[0061] In an embodiment of the present invention, the data processing and control server may send a simulator control instruction to the signal simulator. The signal simulator may receive the simulator control instruction and generate a simulation signal based on the simulator control instruction to generate a GNSS simulation scenario, simulating the initial signal sent by the GNSS under the influence of at least one of ionospheric scintillation, the obstruction of masts and chimney structures that may exist around the shipborne GNSS receiver, and the reflection of the GNSS signal by the sea surface during the propagation process, and the signal related to the carrier simulation trajectory after the transformation.

[0062] In some embodiments of the present invention, the three-axis turntable is used to receive the turntable control instruction sent by the data processing and control server; and generate the simulated swaying state information based on the turntable control instruction.

[0063] In an embodiment of the present invention, the data processing and control server can send turntable control instructions to the three-axis turntable. The three-axis turntable can receive the turntable control instructions sent by the data processing and control server, and generate simulated swaying state information based on the turntable control instructions, so that the three-axis turntable simulates the swaying state of the ship under the action of waves on the sea surface.

[0064] In some embodiments of the present invention, the three-axis turntable is used to rock in at least one of a pitch direction, a roll direction, and a yaw direction based on the simulated rocking state information.

[0065] In an embodiment of the present invention, the three-axis turntable can sway in at least one of the pitch direction, the roll direction, and the yaw direction when simulating the swaying state of a ship under the action of waves on the sea surface based on the simulated swaying state information. The three-axis turntable can also use sinusoidal rotation to simulate pitch angle shaking, etc. The user can continuously change the input according to the navigation needs through the human-computer interaction interface to simulate complex sea conditions. The static state of the three-axis turntable is defined as the standard state as a reference value for subsequent tests.
