Abstract

In Global Navigation Satellite System (GNSS), the integrated system will provide twice and more satellites than individual system, visible satellite number can reach more than 40 in the same epoch moment, the satellite selection algorithm is very important for increasing navigation location precision, and visible satellite geometry is the most crucial factor. The classical optimal algorithm selects n satellite subsets from m visible satellites with the minimum GDOP (Geometry Dilution of Precision), its computation amount is very large especially for much many satellites. This paper presents a new satellite selection algorithm, the selection algorithm is simulated and validated by a software simulation. This algorithm can get the GDOP value close to the minimal GDOP value, and its computation amount is very small.
