Abstract :
This paper presents a common method to locate the satellite interference using two-satellite techniques and cross ambiguity function (CAF). The 2D computation over a long integration time brings great burden on the digital processing. Fast algorithm approach using satellite ephemeris was introduced in this paper with a detail analysis on the computation. The effectiveness of the approach is backed up with successful experiments using actual signals relayed by two satellites.
