Abstract Abstract—The performance of the basic GPS system has been augmented by the technique of Differential GPS (DGPS) for military as well as civilian uses. Performance evaluation of a DGPS system requires the availability of DGPS corrections as functions of time. In many parts of the world, a lack of base stations and other infrastructure makes it impossible to have the desired quality and quantity of data. Thus, it is useful to develop a system, which can generate GPS measurements for an arbitrary number of truth points. In this paper, Wavelet Neural Network (WNN) is used to online predict the corrections for Selective Availability (S/A) on and off. Gradient Descent (GD) and Particle Swarm Optimization (PSO) are used to train and optimize the weights of WNN. Experimental results for the errors real-time prediction show the feasibility and effectiveness of WNN-PSO. The results prove that the proposed WNN-PSO method has better accuracy in a low cost GPS receiver.
