hour angle system
解釋
時角系統-
The results indicate that : with sa, the position precision of the integrated system, whose gyro drifting is 50 degree / hour and whose accelerator offset is 0. 001g, is 60 meters, its velocity precision is about 1. 75m / s out and its attitude angle precision is about 0. 25 degree. without sa, the position precision is about 20 meters, its velocity precision is about 0. 5m / s and its attitude angle precision is about 0. 1 degree. when the signal of gps is lost, the growing rate of the integrated system error is much lower than that of sins system
模擬結果表明:對于陀螺漂移為50度/小時、加速度計零偏為0 . 001g的組合系統,在有sa的情況下,位置精度大約為60米,速度精度大約為1 . 75米/秒,姿態角精度大約為0 . 25度;在無sa的情況下,位置精度大約為20米,速度精度大約為0 . 5米/秒,姿態角精度大約為0 . 1度;在gps信號丟失時,系統誤差的增長速度比純sins系統明顯減緩。
