From Tomas Fri Nov 20 18:44:10 1992 From: Tomas (Tomas) Date: 20 NOV 1992 18:44:10 Subject: [IGSREPORT-19] ESA analysis report Message-ID: *********************************************************************** IGS Electronic Report 20-NOV-1992 18:44:10 Message Number 19 *********************************************************************** From: Tomas Martin Mur Subject: ESA analysis report ------------------- ------------------------- ANALYSIS CENTRE: ESA/ESOC ------------------------- OUTLINE OF THE ESTIMATION OF GPS-ORBITS AND EARTH ROTATION PARAMETERS AT THE ESOC PROCESSING CENTER FOR IGS J.M.Dow, J.Feltens, T.Martin Mur, C.Garcia-Martinez Description of analysis for period 1992 November 8 - 14 1. SOFTWARE USED: GPSOBS/BAHN5 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 * * * In day 319 satellite SV-11 ( PRN#3 ) was not tracked at all by several stations and only partially tracked by others when visible. The rms of the differences between the orbit obtained for this satellite on day 319 and the orbit propagated from day 318 is bigger than for other days, but not unusually high. 3. GROUND STATIONS (if being estimated, one position (X,Y,Z) every day): The following table gives an overview over the ground stations that have been included into the GPS-data processing at ESOC. Except where otherwise noted ("remarks"), corrections are taken from IGS Mail No. 90 - IGS site information and coordinates,updated version of IERS/IGS Tables in IGS Mail No. 65 - (Boucher and Altamimi). ______________________________________________________________________ | | | GPS WEEK 670 | | | | 3 3 3 3 3 3 3 | | | | 1 1 1 1 1 1 1 | SITE | COUNTRY |CODE| 3 4 5 6 7 8 9 | REMARKS -------------------|-------------|----|---------------------|--------- Albert Head | Canada |ALBH| e - - - - - - | Algonquin | Canada |ALGO| F F F F F F F | CANB/Tidbinbilla | Australia |TIDB| e - - - - - - | Penticton | Canada |DRAO| F - - - - - - | Fairbanks | U.S.A./AK |FAIR| F F F F F F F | Goldstone | U.S.A./CA |GOLD| F F F F F F F | Graz | Austria |GRAZ| F F F F F F F | Hartebeesthoek | South Africa|HART| F F F F F F F | Hobart/Tasmania | Australia |HOBA| e e e e e e e | JPL Mesa | U.S.A./CA |JPLM| e e e e e e e |owm. est.
