Gyroscopes and gyroscope information acquisition systems are important components of spacecraft. Fiber optic gyroscopes are a new type of gyroscopes. The basic working principle of fiber optic gyroscopes, the Sagnac effect, is introduced. The hardware and software of the gyroscope information acquisition system are designed. DSP chips are used for data acquisition and processing, which are fast and accurate, meeting the real-time requirements. The fiber optic gyroscope combination is introduced. The data acquisition and temperature acquisition circuit implementation technology based on TI\'s DSP product TMS320VC5402 chip is introduced. According to different application environments, the reliability design of the circuit is given. This design can be flexibly extended to the design of embedded systems for other inertial products.
