[0034] As described in the background section, testing of the orientation module needs to be conducted in an external environment. Therefore, it is often affected by changes in satellite signals, external environment, and weather, leading to inaccurate test results and affecting the efficiency and reliability of the orientation module testing.

[0035] In view of this, this application provides a method for detecting a directional device. In a first test scenario, a first playback device and a second playback device receive a first satellite signal. When the first playback device and the second playback device receive the first satellite signal at the same time, the first playback device and the second playback device store the received first satellite signal respectively. In a second test scenario, the first playback device transmits the first satellite signal to the first directional module through a first antenna, and the second playback device transmits the first satellite signal to the second directional module through a second antenna. By collecting and replaying the signals, the accuracy of the directional result of the directional device is detected without being affected by the external environment, thus improving the accuracy of the detection result.

[0036] In some embodiments, such as Figure 1 The diagram shown is a schematic flowchart of a method for detecting a directional device according to an embodiment of this application. The method may specifically include the following steps:

[0037] S101. In the first test scenario, the first playback device receives the first satellite signal, and the second playback device receives the first satellite signal.

[0038] In some embodiments, before conducting the test, it is necessary to select the first test scenario. The first test scenario is determined based on the product requirements of the orientation device under test, and the electrical performance of the orientation device is determined through pre-testing to ensure that it is normal, whether the orientation device can receive observation data from different satellite systems, and whether the orientation device can obtain the correct orientation result. Specifically, the first test scenario can be selected as needed.

[0039] In some embodiments, one end of the first antenna is connected to a first power divider, one end of the second antenna is connected to a second power divider, and the other end of the first antenna is used to receive a first satellite signal, and the other end of the second antenna is used to receive the first satellite signal.

[0040] In some embodiments, the first power divider distributes the first satellite signal to the first navigation chip and the first playback device, the first playback device receiving the first satellite signal; the second power divider distributes the first satellite signal to the second navigation chip and the second playback device, the second playback device receiving the first satellite signal.

[0041] In some embodiments, the first navigation chip processes the first satellite signal to obtain first positioning information and first time information, the second navigation chip processes the first satellite signal to obtain second positioning information and second time information, the first navigation chip is connected to the first terminal, and the second navigation chip is connected to the first terminal. The connection method can be through a serial port connection, and the first terminal can be a desktop computer device.

[0042] It should be noted that this first scene may be located indoors or outdoors.

[0043] S102. When the first time information is the same as the second time information, the first playback device and the second playback device respectively store the received first satellite signal.

[0044] In some embodiments, the first time information and the second time information represent the time of acquiring the first satellite signal, because in the scenario of satellite orientation, the orientation device needs to acquire the first satellite signal at the same time. In this embodiment, the first orientation module and the second orientation module are modules in the orientation device that implement the orientation function, so the orientation function of the first orientation module and the second orientation module is detected.

[0045] In some embodiments, when the first time information and the second time information are different, two cache variables are designed to store the result of decoding the first satellite signal. The decoded result includes time, pseudorange, carrier phase, carrier-to-noise ratio, etc. The data synchronization calculation is then performed using this time to eliminate the impact of not acquiring the first satellite signal at the same time on the orientation result.

[0046] S103. In the second test scenario, the first playback device sends the first satellite signal to the first directional module through the first antenna, and the second playback device sends the first satellite signal to the second directional module through the second antenna.

[0047] The first directional module requests the first satellite signal from the first playback device via the first antenna;

[0048] The second orientation module requests the first satellite signal from the second playback device via the second antenna.

[0049] In some embodiments, the first playback device is connected to one end of the first antenna, the second playback device is connected to one end of the second antenna, the other end of the first antenna is connected to the first directional module, and the other end of the second antenna is connected to the second directional module.

[0050] In some embodiments, the first orientation module and the second orientation module process the first satellite signal respectively to obtain a first orientation result and a second orientation result. The first orientation module sends the first orientation result to the first terminal, and the second orientation module sends the second orientation result to the first terminal. The first orientation module is connected to the first terminal, and the second orientation module is connected to the first terminal. The connection method can be that the first orientation module is connected to the first terminal via a serial port, and the second orientation module is connected to the first terminal via a serial port.

[0051] In some embodiments, the side of the first directional module connected to the first antenna can be connected to a power divider, and multiple directional modules can be connected through the power divider to test the directional function of the multiple directional modules.

[0052] The first terminal compares the first orientation result with the first standard result, and the first terminal compares the second orientation result with the second standard result. The first orientation result is obtained by the first orientation module processing the first satellite signal, and the second orientation result is obtained by the second orientation module processing the first satellite signal.

[0053] When the difference between the first orientation result and the first standard result is within a first threshold range, the first terminal determines that the first orientation result is correct; when the difference between the second orientation result and the second standard result is within a second threshold range, the first terminal determines that the second orientation result is correct.

[0054] It should be noted that the first threshold and the second threshold are set based on reference values ​​obtained from higher-level surveying instruments before the method of this embodiment is executed. Therefore, the first satellite signal is used by the first terminal to determine whether the first orientation result and the second orientation result are correct. The first orientation result is obtained by the first orientation module processing the first satellite signal, and the second orientation result is obtained by the second orientation module processing the first satellite signal.

[0055] It should be noted that this second scene is located indoors.
