| Abstract: | Integrating GPS multi-antenna attitude module with low cost Fibre-Optical Gyroscope IMU, taking PC104 as integration navigation calculating platform, using loosely-coupled integrating algorithm with cyclic adjusting, the paper has constructed a low-cost vehicle attitude determination system with high accuracy and reliability, which applied to mobile satellite communication system successfully. The integrated system has been tested a great deal and has excellent quality such as: initialization time less than 2 minutes under stationary circumstance, dynamic attitude accuracy better than 0.1 degree, and data update rate up to 100Hz. This technology can be applied to maritime and aviation furthermore and has promising prospect. |
