摘要
分析了GPS测量航向时的误差来源,结合试验情况建立修正模型进行GPS航向改正,并运用到实际试验中进行模型检验,结果证明该修正方法切实可靠,能够在一定程度上提高试验精度和可靠性。
This paper analyzes the reason and source of course measuring errors of GPS. And it builds error model to reduce the course measuring errors and tests the model. Test results show that the proposed method is effective and can improve the precision and reliability in some ways.
