[0011] First, the terms involved in one or more embodiments of this specification are explained.

[0012] Direction-finding baseline: Also known as differential baseline, it is an important concept in the Differential Global Positioning System (DGPS), especially in the Real-Time Kinematic (RTK) technology. The differential baseline refers to the virtual line segment formed between two GNSS receivers, one of which is used as a reference station (Base Station) and the other as a rover station (Rover Station). The length and direction of the differential baseline can be obtained by processing the data collected by the two receivers.

[0013] GNSS: Global Navigation Satellite System, a global satellite navigation system, is used to provide positioning, navigation and timing services on a global scale. It is the same name for individual satellite navigation and positioning systems such as the Beidou system, GPS, GLONASS, and Galileo system, and can also refer to their enhanced systems.

[0014] BD: Beidou, a satellite navigation system.

[0015] In practical applications, it is usually necessary to calibrate the navigation antenna of a communication device, which can be a portable satellite communication station or radar station. Figure 1 , Figure 1 FIG. 1 shows a schematic diagram of a first antenna heading determination system provided according to an embodiment of the present specification. Figure 1 As shown, a communication device 100 is provided with a communication antenna 102, and two navigation antennas 104 are provided on both sides of the communication antenna 102. The navigation antennas may be, for example, GPS or BD. In this way, the reflecting surface of the communication antenna 102 may be used as a direction finding baseline, and heading calibration may be performed through the two navigation antennas 104. Generally, when heading calibration is performed using a double differential method, a fixing device of the communication antenna may be fixedly connected to a device to be calibrated, so that the direction finding baseline between the two navigation antennas is relatively short, resulting in low heading calibration accuracy.

[0016] See also Figure 2 , Figure 2 FIG. 1 shows a schematic diagram of a second antenna heading determination system provided according to an embodiment of the present specification. Figure 2 As shown, a communication device 200 is provided with a communication antenna 202, which is arranged on an antenna mount 204. An extension rod 206 is fixed on the antenna mount 204, and two navigation antennas 208 are fixed on both ends of the extension rod 206, thereby extending the direction finding baseline. However, the rigidity and straightness of the extension rod will be affected, and the consistency of the heading calibration result will be poor after the extension rod is repeatedly disassembled and assembled. Therefore, an effective technical solution is urgently needed to solve the above problems.

[0017] In this specification, a method for determining an antenna heading is provided. This specification also relates to an antenna heading test system, which will be described in detail one by one in the following embodiments.

[0018] See also Figure 3 , Figure 3 A flow chart of a method for determining antenna heading according to an embodiment of the present specification is shown, which specifically includes the following steps.

[0019] Step 302: Control a light source generator to emit a light beam, wherein the light source generator is disposed in a communication device.

[0020] Specifically, the antenna heading determination method provided in the embodiments of this specification can be applied to the server of a communication device, and can also be applied to an antenna heading determination system, which may include a communication device for realizing heading calibration of a navigation antenna of the communication device.

[0021] The communication device may be, for example, a satellite communication station or a radar station, and optionally, the communication device may be a portable satellite communication station or a radar station. The light source generator may be understood as a device capable of emitting a light beam, and the light source generator may include but is not limited to a laser diode, a light emitting diode, and a laser.

[0022] Based on this, the server of the communication device can control the light source generator to emit a light beam.

[0023] In one embodiment of the present specification, the light source generator may be fixedly connected to the antenna of the communication device. For example, the light source generator may be disposed on an antenna mount of the communication antenna of the communication device.

[0024] In another embodiment of the present specification, the light source generator and the antenna of the communication device may not be fixedly connected, that is, the light source generator and the antenna of the communication device may not be in contact.

[0025] In a specific implementation, the communication device is provided with an antenna mount, the antenna mount is used to place a communication antenna of the communication device, and the antenna mount is provided with a reference mark; The controlling the light source generator to emit a light beam comprises: The light source generator is controlled to emit a light beam so that the light beam trajectory coincides with or is parallel to the reference graticule.

[0026] The reference marking line can be understood as a straight marking line processed and manufactured on the antenna mount.

[0027] Based on this, the service end of the communication device can control the light source generator to emit a light beam so that the emitted light beam trace coincides with or is parallel to the straight line engraved on the antenna mount.

[0028] In addition, the reference graticule may also be set at other positions of the communication device.

[0029] In practical applications, see Figure 4 , Figure 4 FIG. 2 shows a schematic diagram of a third antenna heading determination system in an antenna heading determination method provided according to an embodiment of this specification. Figure 4As shown, the communication device 400 includes a communication antenna 402 and an antenna mount 404 . The antenna mount 404 is processed with reference scribed lines, and a light source generator 406 can be arranged on the antenna mount 404 .

[0030] In summary, by processing and manufacturing reference scales on the antenna mount, the light beam emitted by the light source generator is made to coincide with or be parallel to the reference scales, so that the heading of the navigation antenna can be calibrated more accurately later.

[0031] In one embodiment of the present specification, the angle between the light beam and the rotation axis of the communication antenna is fixed.

[0032] Specifically, the light beam emitted by the light source generator forms a fixed angle with the rotation axis of the communication antenna, thereby facilitating subsequent heading calibration of the navigation antenna.

[0033] In one embodiment of the present specification, the light source generator is a linear laser, and the linear laser and the communication antenna are fixedly connected.

[0034] Specifically, the light source generator may be a linear laser, and the linear laser may be fixedly connected to the communication antenna by being fixed on an antenna mount. The light beam emitted by the linear laser may be a linear laser.

[0035] In another embodiment of the present specification, the light source generator is a point laser, the point laser is fixedly connected to a rotating mechanism, the rotating mechanism rotates to convert the point light beam emitted by the point laser into a line light beam, and the rotating mechanism is fixedly connected to the communication antenna.

[0036] Specifically, the light source generator may be a point laser, and the point laser may emit a laser point light source. The point laser may be fixed on a rotating mechanism, and a fixed connection interface is provided between the rotating mechanism and the communication antenna, and the fixed connection between the rotating mechanism and the communication antenna may be achieved through the fixed connection interface. The rotating mechanism rotates, driving the point laser to rotate, so that the laser point light source emitted by the point laser moves in a line, and the projected laser point draws a straight line on the ground or other carrier where the communication equipment is placed as the point laser rotates, thereby achieving the emission of a straight line light beam.

[0037] It can be understood that the linear laser emitted by the linear laser and the linear light beam emitted by the point laser as the rotating mechanism rotates coincide with or are parallel to the reference scale line.

[0038] Step 304: Determine a target installation position of the navigation antenna according to the emission direction of the light beam, wherein a distance between the target installation position and the communication device is greater than a preset distance threshold.

[0039] The navigation antenna can be understood as a GNSS antenna, and the navigation antenna can be, for example, a GPS (but not limited to GPS). The distance between the target installation location and the communication device can be understood as the distance between the antennas at the target installation location and the communication location. If the distance between the target installation location and the communication device is greater than a preset distance threshold, it can be indicated that the navigation antenna installed at the target installation location is not on the communication device, for example, the navigation antenna installed at the target installation location can be placed on the ground.

[0040] In practical applications, combined with the above Figure 4 , Figure 4 The navigation antenna 408 is also included. The distance between the target installation position where the navigation antenna 408 is located and the communication antenna 402 of the communication device can be greater than a preset distance threshold, so that the navigation antenna 408 is not on the communication device.

[0041] Based on this, the target installation position of the navigation antenna can be determined according to the emission direction of the light beam, so that the distance between the navigation antenna and the communication device is greater than a preset distance threshold.

[0042] In a specific implementation, determining the target installation position of the navigation antenna according to the emission direction of the light beam includes: In the emission direction of the light beam, the target installation position of the navigation antenna is determined so that the light beam irradiates the center of the navigation antenna.

[0043] Specifically, in the emission direction of the light beam, the target installation position of the navigation antenna can be determined, so that the light beam is irradiated on the center of the navigation antenna, thereby realizing the determination of the target installation position of the navigation antenna.

[0044] In practical applications, there are two navigation antennas, and the two navigation antennas are respectively located on both sides of the communication device; The controlling the light source generator to emit a light beam comprises: Controlling the light source generator to emit light beams to both sides of the communication device; Determining the target installation position of the navigation antenna according to the emission direction of the light beam includes: In the emission direction of the light beam, the target installation position of each navigation antenna is determined so that the light beam irradiates the center of each navigation antenna.

[0045] Specifically, the light source generator can be controlled to emit two light beams to both sides of the communication device, and the target installation positions of the two navigation antennas are respectively determined in the emission directions of the light beams, so that the two light beams are respectively irradiated on the centers of the two navigation antennas.

[0046] In summary, placing two navigation antennas facilitates the subsequent calculation of the heading angle using a double differential GPS method.

[0047] Furthermore, determining the target installation position of each navigation antenna in the emission direction of the light beam so that the light beam irradiates the center of each navigation antenna includes: In the emission direction of the light beam, according to a preset distance length, determining the target installation position of each navigation antenna so that the light beam irradiates the center of each navigation antenna; The preset distance length is the straight-line distance between the two navigation antennas.

[0048] Specifically, the target installation positions of the two navigation antennas can be determined according to a preset distance length in the emission direction of the two light beams, so that the two light beams are respectively irradiated at the centers of the two navigation antennas, and the distance between the two navigation antennas is the preset distance length.

[0049] In practical applications, combined with the above Figure 4 The preset distance length can be understood as the length of the direction finding baseline. The preset distance length can be 2 meters, 4 meters, 6 meters, 8 meters, 10 meters, etc. The preset distance length can be selected according to actual needs.

[0050] In summary, by setting the distance between the two navigation antennas to a preset distance length, the length of the direction finding baseline between the two navigation antennas can be customized, thereby ensuring the dynamic requirement of the accuracy of the heading calibration of the navigation antennas.

[0051] Step 306: Calculate the target heading angle of the navigation antenna according to the positioning information of the navigation antenna installed at the target installation position, and adjust the navigation antenna from the current heading angle to the target heading angle.

[0052] The positioning information can be understood as the signal received by the navigation antenna. The current heading angle can be understood as the heading angle of the navigation antenna before the heading calibration of the navigation antenna. The target heading angle can be understood as the heading angle obtained by the heading calibration of the navigation antenna.

[0053] Specifically, the target heading angle of the navigation antenna can be calculated based on the signal received by the navigation antenna installed at the target installation position through a dual differential GPS method, and the navigation antenna can be adjusted from the current heading angle to the target heading angle to achieve antenna heading calibration.

[0054] In specific implementation, the target heading angle may be a heading angle of a different coordinate system. Then, the target heading angle of the navigation antenna may be calculated based on the positioning information of the navigation antenna installed at the target installation position, and the navigation antenna may be adjusted from the current heading angle to the heading angle of the different coordinate system.

[0055] In practical applications, the communication device can be placed on the ground, so the target installation position of the navigation antenna can also be on the ground. Accordingly, the navigation antenna installed at the target installation position can be understood as the navigation antenna placed at the target installation position on the ground.

[0056] In a specific implementation, the target heading angle of the antenna of the communication device is calculated according to the positioning information of the navigation antenna installed at the target installation position, including: Determine first positioning information received by a first navigation antenna of the two navigation antennas, and second positioning information received by a second navigation antenna; Calculating a phase difference between the first navigation antenna and the second navigation antenna according to the first positioning information and the second positioning information; The target heading angles of the first navigation antenna and the second navigation antenna are calculated according to the phase difference.

[0057] The first navigation antenna may be understood as one of the two navigation antennas, and the second navigation antenna may be understood as the other of the two navigation antennas. The first positioning information may be understood as a signal received by the first navigation antenna, and the second positioning information may be understood as a signal received by the second navigation antenna.

[0058] Based on this, the signal received by one of the two navigation antennas can be determined, and the signal received by the other navigation antenna can be determined. According to the signals received by the two navigation antennas, the phase difference between the two navigation antennas is calculated, and according to the phase difference, the target heading angles of the two navigation antennas are calculated.

[0059] In addition, a reference point for heading measurement can be set on the antenna that needs heading measurement. The position of the reference point for heading measurement on the antenna that needs heading measurement can be measured using a theodolite, and then the heading of the antenna that needs heading measurement can be calculated.

[0060] In summary, the target heading angle is calculated by the signal received by the navigation antenna, so as to realize the heading calibration of the antenna of the communication device.

[0061] In practical applications, the target heading angle of the communication device under the same circumstances can be calculated multiple times, and the calculation results are consistent, thereby ensuring high repeatability consistency of the heading calibration.

[0062] To sum up, in the above method, the target installation position of the navigation antenna is determined by utilizing the light beam emitted by the light source generator, so that the distance between the target installation position and the communication equipment is greater than a preset distance threshold, thereby achieving an extension of the direction-finding baseline. As a result, the target heading angle of the antenna calculated based on the positioning information of the navigation antenna installed at the target installation position is more accurate, thereby improving the accuracy and consistency of the antenna's heading calibration.

[0063] The following combination Figure 5 and attached Figure 6 Taking the application of the antenna heading determination method provided in this specification in heading calibration as an example, the antenna heading determination method is further described. Figure 5 A processing flow chart of a first antenna heading determination method provided in an embodiment of the present specification is shown, which specifically includes the following steps.

[0064] Step 502: Control the linear laser to emit light beams to both sides of the communication device.

[0065] Step 504: In the emission direction of the light beam, the target installation positions of the two navigation antennas on both sides of the communication device are determined according to a preset distance length, so that the light beam is irradiated at the center of the two navigation antennas.

[0066] Step 506: Calculate the target heading angles of the two navigation antennas of the communication device according to the positioning information of the two navigation antennas installed at the target installation position.

[0067] Step 508: Adjust the two navigation antennas from the current heading angle to the target heading angle.

[0068] Figure 6 A processing flow chart of a second antenna heading determination method provided in an embodiment of the present specification is shown, which specifically includes the following steps.

[0069] Step 602: Control the point laser to emit a point light beam to both sides of the communication device, control the rotation mechanism to rotate, drive the point laser to rotate, and convert the point light beam into a line light beam.

[0070] Step 604: In the emission direction of the linear light beam, according to a preset distance length, the target installation positions of the two navigation antennas on both sides of the communication device are determined so that the light beam is irradiated at the center of the two navigation antennas.

[0071] Step 606: Calculate the target heading angles of the two navigation antennas based on the positioning information of the two navigation antennas installed at the target installation position.

[0072] Step 608: Adjust the two navigation antennas from the current heading angle to the target heading angle.

[0073] In the above method, the target installation position of the navigation antenna is determined by utilizing a linear laser or a point laser and a rotating mechanism to emit a light beam, so that the distance between the target installation position and the communication device is greater than a preset distance threshold, thereby achieving an extension of the direction-finding baseline. As a result, the target heading angle of the navigation antenna calculated based on the positioning information of the navigation antenna installed at the target installation position is more accurate, thereby improving the accuracy and consistency of the heading calibration of the navigation antenna.
