“…The tropospheric biases between GPS and VLBI resulting from the use of relative PCVs correspond well to the results of Schuh and Bo¨hm (2003) who analyzed 11 co-located sites altogether. Their investigations also showed that the bias is always positive, the individual values ranging from +1.4 mm to +13.5 mm (Onsala: +4.8 mm).…”

“…At the end of the paper, the influence of antenna PCVs on the biases between total tropospheric zenith delays derived from different space geodetic techniques is discussed. Schuh and Bo¨hm (2003) who analyzed the GPS and VLBI (very long baseline interferometry) derived troposphere parameters for identical times at 11 co-located sites found out that all mean values of the total zenith delays derived by GPS are larger than those derived by VLBI. Haas et al (2003) get similar results for the Onsala Space Observatory from an analysis of long time series of integrated precipitable water vapor (IPWV) from four different techniques (GPS, VLBI, water vapor radiometers (WVRs) and radiosondes).…”

“…Thus VLBI can be used as an independent source, in addition to radiosonde or water vapor radiometer, to assess the quality of the GPS derived atmospheric information. The International VLBI Service for Geodesy and Astrometry (IVS) provides tropospheric products since 2002 [44]. The Australian Long Baseline Array is part of the Australia Telescope National Facility.…”

“…Concerning the troposphere, early studies [53] have shown that precision of 1 cm in zenith path delay can be obtained using three satellites (equivalent to 2 mm in Integrated Precipitated Water). More recent studies show that 6 to 8 mm can be obtained when using five satellites during the CONT02 campaign in comparison with VLBI and GPS results [39,40]. However, we must also say that these results can only be obtained after a onemonth delay, making them totally useless for any assimilation in a weather prediction model.…”
