Some error sources in GPS surveys, such as linearization error and orbital bias, are well known and do not require further investigation. The impact of these errors in GPS + pseudolite observations can be different and must be considered separately. This paper presents influence of orbital bias and linearization error on single differenced pseudolite observations.
In this paper the method of geodetic control network elaboration is presented. That network consists of GPS vectors and distances measured classically. The method of reduction of GPS vectors from WGS84 to local coordinate system was described. Common adjustment of GPS vectors and distances in a local coordinate system was performed. The observations set was obtained from measurements of geodetic control...
