摘要
相对差分定位技术是差分定位技术的一种推广,这种方法的优点是不需要基准点的精确坐标就能用差分定位的方法给出目标之间的相对位置。在对传统的绝对差分定位原理进行分析的基础上,研究了相对伪距差分定位技术,得到了求解相对位置的状态方程。利用高精度的Novatel DL-V3接收机建立了实验系统,并进行了实际测量和解算。结果表明,该相对伪距差分方法定位精度较高,解算速度快,有一定应用价值。
The relative difference positioning technique is a promotion of difference positioning technique. The advantage of this method is the relative position between targets can be given without reference point for the base station. Based on the analysis of the traditional absolute difference positioning theory, the relative pseudorange difference positioning technique was researched and the equation of state which solves relative position was given. Through the establishment of experiment system by using high-precision Novatel DL-V3 receiver, the actual measurement was taken. Results show that the arithmetic has higher positioning accuracy and faster solution, and can be applied to the relative positioning.
