Abstract:

A prototype geodetic receiver is being developed for application with the NAVSTAR Global Positioning System. Data obtained with an experimental version of the receiver applied to simulations of performance of the prototype version indicate that the relative positions of stations 10 to 100 km apart can be obtained with 1- to 2-cm accuracy after 6 hr of observations provided that water-vapor radiometers are used to obtain tropospheric refraction correction data. Initial studies show that the use of surface weather data, but without water-vapor radiometers, would give 2- to 5-cm accuracies, but a more realistic modeling of the errors under these conditions is required.
