SOFTWARE USED: GPSOBS/BAHN-Version 5 2. MODELS USED AND PARAMETERS ESTIMATED/FIXED: For a description of models and parameters used ==> see IGS - Mail 51 For updates of the models and parameters used ==> see IGS - Mail 114 and see IGS - Rep. 224,277 3. REMARKS: With the beginning of week 0724 we have included SV-34/PRN04 into our routine IGS-processing and we have added the two sites RCM5 (Richmond) and KOSG (Kootwijk). The orbit accuracy of SV-09/PRN13 is again of reduced quality, since it has only been tracked in parts of its orbit. The track- ing data is only about 50% of the data obtained for the other satellites. 4.
