Combined navigation system based on fiber-optic gyroscope IMU and module DEV. The IMU uses a fiber-optic gyroscope, a quartz flexible accelerometer, a high-precision IF conversion circuit, and a DSP/FPGA-based signal acquisition and processing circuit, which can simultaneously measure the acceleration and angular velocity information of the carrier in three directions. The DEV Acquisition and Combined Navigation Module has a built-in high-performance satellite receiver (supporting two antennas), a computing board and an odometer acquisition board. Post-processing supports self-built base stations and is compatible with the differential data format of major differential service providers. It is not limited by baselines, easy to assemble and has high operational efficiency.
