A Multi-Task High-Precision Real-Time System Software Realization Method Based on Five-self Inertial Group

Inertial group is an important part of the missile control subsystem. In order to realize the attitude control and navigation guidance during the flight of the missile, it has the ability to provide the measurement information of apparent acceleration and angular velocity and the reference frequency standard source. A navigation parameter solving system with gyro and accelerometer as sensitive devices is established. Aiming at the new five-self (self-detection, self-alignment, self-calibration, self-retention, self-compensation) inertial group, a multi-task high-precision real-time system software realization method based on multi-core DSP processor is proposed to solve the problem of multi-cycle and multi-task data real-time acquisition and processing and use, and realize the high-precision five-self function and real-time data transmission function in the five-self process.
