Abstract : Comparison of TRANSIT satellite orbits computed from Geoceiver observations using both real and NWL standard surface weather reveals maximum orbit differences of less than 2.0 meters. Furthermore, the introduction of refraction bias parameters into the orbit solutions can significantly increase solution accuracies. The results indicate that standard weather used in the NWL tropospheric refraction model with refraction bias parameters is adequate for orbit determination. (Author)
