In this study, two-stage estimation of aircraft's position and velocity by Global Navigation Satellite System (GNSS) algorithm is presented. In first stage, the distances between the GNSS satellites and aircraft (pseudoranges) and the radial velocities are measured. By this GNSS generated data, an equation system for aircraft is presented and solved. In the second stage, the solutions of the firs stage are improved by Kalman Filtering process.
