Carrier Phase Dual Differential GPS Measurement Error Analysis Based on Wavelet Analysis

Nowadays,some personalized observation factors still haven't been overcome as the errors in GPS surveying in modern technology of GPS dual carrier phase,such as Multipath effect,the receivers interfered by electrical/heat and various noise.Making use of wavelet transform,we can effectivly separated the influence of different errors in GPS surveying from the measurement result by Multiscale decomposing and screening to get test the GPS positioning accuracy improved.
