In addition to the function of the conventional star tracker, our star tracker also has a spatial orientation measurement function. The star tracker can calculate the relative orientation between the target satellites by identifying the target optical satellite or other target optical signals and then calculate the spatial distribution of the target formation. This project has made its first flight on Longjiang-1. In order to further mature this technical solution, the company conducted a large number of outdoor tests and satellite-ground tests to verify the relative bearing measurement function.
On February 19, 2019, the PST3S star tracker photographed on the ground and identified the photoelectric Morse code sent by the piaochong-1 satellite. The video shows that the star tracker attitude calculation can still work normally when the moon enters the field of view
