Computer Error Analysis of Tropospheric Effects for the NAVSTAR Global Positioning System

Abstract

A model for tropospheric delay of a radio signal from a satellite, is used to perform a three-dimensional tropospheric error analysis for the NAVSTAR Global Positioning System (GPS). A program to evaluate the error as a function of satellite positions and elevations, user altitude, and surface index of refraction is developed. It is found that the order of magnitude of the tropospheric errors is such that these errors are not an impediment to possible aircraft precision approaches using NAVSTAR. An extensive bibliography of NAVSTAR and satellite navigation literature is included.
