Abstract:

An accurate method of identifying accelerometer error parameters in the absence of high precision test turntable is proposed. The method takes static multiposition acceleration norm for observation and stan dard variance of norm error of acceleration gravity for index, identifying error parameters of accelerometer with artificial fish swarm algorithm. Simulation analysis on the static 24 positions is made and the accelerometer parameters identification on fiber optic gyro strapdown inertial navigation system is developed. In addition, a 24 hours static navigation test is taken. Both the simulation and test results show that the identification method for error parameters of accelerometer provided by the article is effective and has a certain practical value.
