Bernese GNSS Software Version 5.2 Tutorial

3 Terminal Session: Pole and Orbit PreparationYou have to apply the same subdaily pole and nutation models as you have used beforewhen you have generated the Bernese formatted pole file (IGS$YD+0.ERP).If you process precise orbits from CODE it is generally not necessary to remove badsatellites. It might become necessary for orbit products from other sources (e.g., from theIGS). Because CODE introduces the correct accuracy code for all its satellites the abovesettings do not harm the import of satellite orbits from CODE.Panel “PRETAB 3: Options for Clocks” contains the options for extracting the satellite clockinformation. The clock values in the precise orbit file are sampled to 15 min. We interpolatewith a “Polynomial degree” of 2 with an “Interval for polynomials” of 12 hours. This is goodenough for the receiver clock synchronization in CODSPP.A message like this is expected:### PG PRETAB: SATELLITE CLOCK VALUES MISSINGSATELLITE : 101FILE NUMBER: 1FILE NAME : ${P}/INTRO/ORB/COD15951.PREPage 20AIUB
