Application and Research of High Precision Data Acquisition for Laser Gyro

Jianzhong WANG

Abstract


With the wider and wider application of laser gyro in the high precision strapdown inertial navigation system, high precision data acquisition and processing is becoming more and more important. In this paper, the output signal of the laser gyro characteristics are divided, FPGA is used to measure the signal acquisition demodulation, frequency multiplication, counting and other functions of the laser gyro signal acquisition. FIR filtering algorithm is used in DSP to extract the angular velocity signal.


Keywords
