Data Acquisition in Inertial Navigation System Based on DSP and A/D

摘要

The paper designs a data acquisition system based on DSP and A/D to meet the requirement of the INS. The data acquisition system acquires the signals of three accelerometers, three gyros and two temperature sensors from ADC controlled by DSP. DSP processes the acquired data and compensates the gyros and accelerators outputs according to the temperature, so as to eliminate the temperature influence on measuring accuracy of INS. Through the testing, the system can meet the demands in application of the INS in speed and accuracy.
