A simple analytic method for the evaluation of the performance of a radio-localization system
Abstract
An analytical method for evaluating the performance of a satellite radiolocalization system is described. The method can be used to estimate the distribution of a set of radiolocalization beacons over the entire earth; and to evaluate the performance of a global positioning system. An illustration of the method is given in the case of a satellite in GEO with a ground based network to provide distance and angular measurements. The covariance of satellite position computations is estimated, taking into account the white measurement noise and the colored modelization noise of the network. The formulas for calculating the elevation, range measurement coordinates, and bearing of the satellite are given in an appendix.
