Anti Interference Clock Error Correction Technology Based on BD3 System

Abstract Beidou-3 (BD3) uses the pseudo range transmission method to calculate clock difference through range. However, due influence of electromagnetic interference, measurement error is too large, which affects timing accuracy power system. This paper first introduces principle Beidou service; Secondly, it calculation method; Finally, combined with method, this presents an anti-interference correction based on Least Mean Square (LMS) filter. According LMS filter, interference distance can be eliminated, and calculated. Then corrected. The simulation results show that feasible effective.
