GPS (Global Positioning System) User Equipment Evaluation Techniques Using a Rotor Mounted Antenna

Abstract

The accuracy of the NAVSTAR Global Positioning System (GPS) permits evaluation of dynamic performance of user equipments by mounting the antenna on a rotor of practical dimension. The reported diameter of the circular path described by the antenna phase centre will depend on Kalman filter characteristics and will tend Rayleigh statistics through measurement delay intervals up to 1 min. This characteristic of system noise and the development of symmetry techniques permits delayed difference measurement of reported diameter of antenna path to an accuracy of better than 0.5 m over 30 min. This method of Kalman error measurement provides a means for establishing a benchmark for integration filter design software simulation. Australia.
