Abstract
An approach is presented for more accurate GPS navigation with selective availability. In this approach, a linearized perturbation model has been obtained. Using the measurement perturbation difference approach, the model is made suitable to formulate the Kalman filter to obtain the estimate of state perturbation and thereby the estimate of the user position and velocity. Simulation results are provided to confirm the efficacy of the approach
