摘　　要：提出了一种新的空中多平台定位算法,算法首先利用空中多平台的预设坐标对多个地面站进行定位,地面站定位结果与自身已知精确坐标求差,利用此差值推算出空中平台预设坐标的误差校正值,然后对预设坐标进行校正,通过多次迭代运算以达到定位精度的要求。最后,对算法进行了仿真验证,仿真结果表明,算法具有稳定可靠的定位性能。A novel algorithm for multiple space vehicles position is presented. With this algorithm the ground stations are positioned using multiple space vehicles and the differences of the positioning results of ground stations and their real coordinates are calculated. Based on the difference, the revised error for space vehicleg coordinate is estimated and then the coordinate is updated. The iterative method is used to achieve the needed precision of the coordinate. Simulation result proves the stability and credibility of the algorithm in space vehicles positioning.
