Because the tradition navigation system that is composed of gyroscopes and accelerometers can’t be applied to missile with high revolves

the non-gyroscope test system composed of the MEMS accelerometers and gaussmeters is designed.The composition and the working principle of the system circuit are introduced

and the method of data acquisition and storage controlled by CPLD is discussed.The testing results on the analog turnplate under different situation prove that the system circuit can completely satisfy the posture testing request

and the good testing wave can be obtained.
