The atmospheric influence on the results from the Swedish GPS network

Abstract The SWEPOS network currently consists of 21 continuously operating GPS stations. The GPS receiver at the Onsala site is collocated with a microwave radiometer measuring the integrated amount of water vapour along the line of sight. We have studied the correlation between GPS estimates of position and variations in the atmosphere using data from the autumns of 1995 and 1996, and found only small correlations between the estimated positions and the atmospheric quantities studied. We are, however, aware of other systematic errors, e.g. caused by radomes above the GPS antennas which may presently dominate the error budget
