Multi-path effect is the GPS measurement error in an important source of serious damage to the GPS measurement accuracy.This article on the multi-path effects on the impact of GPS measurement error,analysis of the multi-path effect of the principle and some features,introduce a number of paths to eliminate or diminish many of the methods of error measures.The analysis focused on the use of multi-path errors weaken the signal to noise ratio of the method to receive the signal from the receiver to isolate multi-path signal components and direct signal component,the multi-path signals to direct traffic through the concept of measuring phase correction to achieve the elimination or weakening of the purpose of multi-path.
