Algorithm of Position Iteration for Satellite Interference Location

With differential time offset and differential frequency offset, the position of the satellite interference can be located by using two-satellite techniques. The position equations are non-linear and they are very difficult to be solved. Scholar Haworth, et al. presented an iterative algorithm. However, the position results by using their iterative algorithm were non-convergent in the experiment. The formulas given by scholar Haworth, et al. are deduced carefully in this paper and some faults of their iterative algorithm are found. Then the iterative algoritltm presented by scholar Haworth, et al. is amended in this paper and the amendment is backed up with a successful measurement in the experiment.
