The error origin of the accelerometer has been analysed via lots of static experiments repeated, and the mathematic model of compensating error is a- chieved. It has been shown that the static output characteristic of the accelerometer is repeated. T he prec-i sion of the SINS can be improved by error compensation of accelerometers.
