基于SOPC的陀螺星敏感器姿态确定系统
Attitude Determination System of Gyros and Star Sensors Based on SOPC
摘要
Abstract
In order to improve the calculating speed of attitude determination algorithm, the Kalman filter processor, which is based on SOPC (System On a Programmable Chip), is designed on the careful analysis of the algorithm with gyros and star sensors.In this processor, the hardware-software partition is made for the algorithm.The software is edited and compiled in the programming environment of Nios Ⅱ IDE, and the hardware is constructed with Hardware Description Language.By the SOPC system, the software and hardware are integrated in one FPGA(Field Programmable Gate Array) chip.Finally, the algorithm is simulated in the actual chip and Matlab under the same condition, respectively.The two simulation results show that, the attitude determination algorithm based on SC)PC system can determine the spacecraft's attitude in a certain precision range correctly and quickly.关键词
