摘要
目前航天系统应用最多的测距方法是侧音测距和伪码测距两种方法,这两种方法都需要在下行遥测中占用专门的测距通道,降低了遥测信号的传输功率和效率。基于遥测的测距方法是以伪码测距为理论基础,通过下行只发送遥测信号就可以达到测距的目的,该技术可有效提高遥测信号传输效率,具有良好的应用前景。
At present,the most widely used ranging methods in aerospace system are side tone ranging and pseudo code ranging,both of these need to occupy a special ranging channel in the downlink telemetry. The transmission power and efficiency telemetry signals will be decreased by these methods. This paper proposes a distance measurement method in telemetry based on the theory of pseudo code ranging. The distance measurement is achieved by sending telemetry signal without descending ranging signal. This technology can improve transmission efficiency and has good prospects.
