摘要: Abstract The error of laser Doppler velocimeter (LDV) based on Janus configuration is analyzed as the vehicle inclines. Analysis shows that LDV depends vertical velocity to horizontal ratio (VHR) only. But measurement accuracy will be not high enough meet requirement self-contained navigation system, if VHR overlarge in powerful rough ground. corrected through an inclinometer whose precision angle needed only 2%. Simulation after correction can limited below 0.1% even reaches 0.3 and pitch 15°.
