A kind of algorithm for increasing accuracy of position location in mobile network system

Since location applications in mobile network communication system need precise location services, it is necessary to design an algorithm to increase location accuracy for the network system. In this paper we introduce a kind of location algorithm based on coordinate conversions and condition number judgment of array norms to improve location accuracy of position estimation. Else we study and simulate on the operation process about geometric conversion and reverse conversion in different coordinate system, the relationship between condition number of location array and coordinate rotation, and the model frame of location algorithm. We prove in theory the feasibility to increase location calculation accuracy by geometric conversion and location array optimum in location network system.
