| Abstract: | The method of angular position and velocity feedback measurement applied in celestial navigation star tracker is presented in this paper. Its component is multipolar and two-speed resolver. The principle and method of coarse channel and fine channel combination error correction are emphasized. The hardware and software design of measurement circuit is given. The computer interface is PC104 bus. This method has been applied in several navigation tracking systems. The practice shows that the guideline and the performance of static and dynamic are ideal. |
