RINEX Formats (1/2) φo Epoch (OBT) OBT offset Epoch (TAI) = Epoch (OBT) + OBT offset φo (L1) φ1 Epoch φ1 (L1) On Board Frequency estimation OSTST/ JASON-2 – Nov11, 2008 - 12
RINEX Formats (2/2) ■ Anomalies detected : Sensitivity of pseudo range to Doppler variation not taken into account : • Pseudo Range Curves over a beacon pass are slanted but centred on zero (no impact on datation assuming passes are balanced) • update of configuration file currently in progress Bias of 51.83 microseconds in [TAI – OBT] field : • Leads in an error of 35 cm on along track position when TAI datation is used • Correction planed mid November Bad interpretation of meteo parameters • Correction planed mid November ■ Reprocessing planed in early December OSTST/ JASON-2 – Nov11, 2008 - 13
