Abstract
In order to investigate duration of session in static GPS method, data from a network of 7 points, with baseline length of from 64 km to 358 km, were processed. The network were observed by Trimble 4000SSE and Trimble 4000SSi with duration of 24 hours. Data extracted from this session were processed as if they were measured in 3, 6, 9 ... 21, and 24 hours session. The results (Baselines, Sloop Closures, Coordinates, and Standard errors of coordinates) of these sessions were compared to 24 hours one. Some conclusions were made, which seem to be useful in selection of duration for the same dimension GPS network for different purposes.
