GPS positioning error evaluation based on fuzzy algorithm
Lei Lu · Journal of Chinese Inertial Technology · 2007
GPS positioning accuracy is influenced by Geometric Dilution of Precision (GDOP), Signal Noise Ratio (SNR) and so on. As GDOP and SNR influence the GPS result obviously, the relationships between them and the precision of GPS were researched separately based on GPS data. Based on Fuzzy arithmetic, a database to evaluate the precision of GPS was introduced. The validity and practicability of this database were proved by experiment.
