In some embodiments, as shown in FIG. 1 , a schematic flowchart of a method for detecting an orientation device provided by an embodiment of the present disclosure is provided. The method may specifically include the following steps:

S101. In a first test scenario, a first playback device receives a first satellite signal, and a second playback device receives a first satellite signal.

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 being tested, and through preliminary testing, it is determined whether the electrical performance of the orientation device is normal in the first test scenario, and whether the orientation device can receive observation data from different satellite systems, and whether the orientation device can obtain correct orientation results. Specifically, the first test scenario can be selected as needed.

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

In some embodiments, the first navigation chip processes the first satellite signal to obtain first positioning information and first time information, and 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 may be through a serial port, and the first terminal may be a desktop computer device.

It should be noted that the first scene is located indoors or outdoors.

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.

In some embodiments, the first time information and the second time information represent the time of collecting the first satellite signal. Because in the satellite orientation scenario, the orientation device is required to collect the first satellite signal at the same time. In this embodiment, the first orientation module and the second orientation module are modules that realize the orientation function in the orientation device, so the orientation functions of the first orientation module and the second orientation module are detected.

In some embodiments, when the first time information is different from the second time information, two cache variables are designed to store the results of decoding the first satellite signal. The decoded results include time, pseudorange, carrier phase, carrier-to-noise ratio, etc., and then data synchronization is solved through the time to eliminate the impact of the first satellite signal collected at different times on the orientation result.

S103. In a second test scenario, the first playback device sends a first satellite signal to the first directional module via the first antenna, and the second playback device sends a first satellite signal to the second directional module via the second antenna.

The first directional module requests the first playback device to acquire the first satellite signal through the first antenna;

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.

In some embodiments, the first orientation module and the second orientation module respectively process the first satellite signal to obtain the first orientation result and the second orientation result respectively. 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 through a serial port, and the second orientation module is connected to the first terminal through a serial port.

In some embodiments, a side of the first directional module connected to the first antenna may be connected to a power divider, and then multiple directional modules are connected through the power divider to test the directional functions of the multiple directional modules.

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 the result obtained by the first orientation module processing the first satellite signal. The second orientation result is obtained by the second orientation module processing the first satellite signal.

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.

It should be noted that the first threshold and the second threshold are set according to reference values obtained by a higher-level surveying and mapping instrument 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.

It should be noted that the second scene is located indoors.
