摘　　要：介绍了天文导航设备星体跟踪器中,以多极双通道旋变为测量元件的角度位置及速度反馈的设计方法。着重介绍了粗精组合纠错的原理和方法,给出了测量电路的硬件及软件设计,微机接口方式为PC104总线。该测量方法被应用于多个导航跟踪系统中。实践证明,其静动态技术指标及性能理想。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 PC 104 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.
