| 摘 要： | 为了克服独立的惯性导航系统无限制的位置误差和 Ｇ Ｐ Ｓ的１ Ｈｚ 慢速数据修正速率的缺陷，本文提出了对两种具有不同输出数据速率运动传感器 Ｇ Ｐ Ｓ与 Ｉ Ｎ Ｓ融合算法，研究了五点二次和两点线性预测的高精度连续融合定位算法，真实 Ｇ Ｐ Ｓ数据和模拟 Ｉ Ｎ Ｓ数据融合的实验证明了该方法的正确性，为在中、高动态环境下的高精度实时连续定位提供了一种新的途径。

| Abstract: | In order to solve the slowly modified rate about 1Hz of a GPS and the infinite position error of an INS,a continuously high accurate positioning algorithm of a linear convex combination of a linear two point and a quadratic five point polynomial to filter and predict GPS/INS positioning data is presented in this paper The integration experiment of real GPS data and simulated INS data has shown the validity of this method It provides a new approach of continuously high accurate realtime position under middle or high dynamic environment |
