卫星干扰源定位系统中的融合定位技术

Transmitter location system using fusion technology

在卫星干扰源定位系统中,星历的不准确对定位带来很大的误差。文章提出一种结合了卫星动力学模型的迭代最小二乘算法估计某一个时刻卫星的位置、速度,使得此时定位结果和校准站位置最吻合。该方法通过对星历的改进,补偿了星历带来的误差。试验表明,该方法提高了对干扰源的定位精度。

Inaccuracy of ephemeris limits the locating accuracy of the satellite interference. In this paper, a new iterative least squares algorithm based on the satellite force model is proposed to compensate the errors in the satellite ephemeris data by deriving a best fit of the position calibrator measurement data. Simulations andex perirnents confirm that the method is suitable for satellite interference location systern.
