Simple model of multi-channel error in GPS measurement

Multi-channel is one of conditions linchpin factors to advance ulteriorly precision of GPS.This paper has ciphered out multi-channel error′s simple model which most affect GPS precision and reflected signal in condition of mirror′s reflecting,according to the characteristic of multi-channel disturbed signal,and has discussed parameters which belong to attenuation factor and GPS receiver′s affection of phase of multi-channel signal due to the antenna height and has processed copy calculation and analyse the emulation of calculation and analysis is also done.
