This paper designed the principle of attitude measurement and a wireless attitude measurement system based on multi-MEMS. It mainly focused on the data processing with extended Kalman filter. This system used the data measured by gyroscope to renew the results of the previous step and used the data measured by accelerator and geomagnetic sensor as measured values to correct the results. The circuit was designed and the algorithm was realized. The system with high accuracy was wireless, small in size and it can be used in different situations. |
