Abstract

This paper gives a novel All-Fiber laser Doppler Velocity Sensor(ALDVS) to measure the relative velocity to the lunar or planetary bodies during the vehicle landing phase. In the beginning of the paper, A brief description of the principle of laser Doppler velocity sensor is given. After that, the paper gives the laser Doppler velocity sensor configuration. The paper introduce the helicopter flight test that was held in Zhengzhou. The altitude of flight is about 3km.The laser Doppler velocity data is analysed. The GPS velocity data and laser Doppler velocity sensor velocity information are compared. Finally, the equivalent distant in moon is calculated and the measurement error is discussed.
