VieVS User Workshop 14 – 16 September, 2011 Vienna Processing Intensive Sessions with VieVS Johannes Böhm

Introduction 2 INT1 (2-3 days latency) Kokee-Wettzell Mo-Fr 18:30 INT2 (e-transfer) Tsukuba-Wettzell Sa-So 7:30 INT3 (e-transfer) Tsukuba-Wettzell-NyAlesund Mo 7:00 Luzum and Nothnagel (2010)

VieVS User Workshop Typically, we need version 4, but in case of INT2 sessions, it is N003.

VieVS User Workshop Remember that.

VieVS User Workshop At least not more than a linear function between the two clocks.

VieVS User Workshop Choose this option. This is important. The time interval should cover the whole session.

VieVS User Workshop Make one constant zenith wet delay per station and do not estimate gradients.

VieVS User Workshop Do not estimate station coordinates.

VieVS User Workshop Only estimate one constant dUT1 per session. (1e-4)

VieVS User Workshop Do not estimate source coordinates.

VieVS User Workshop

VieVS User Workshop I would say ok. I would not treat this as outlier if there are only 15 observations.

VieVS User Workshop This is not too much.

VieVS User Workshop Could be better but ok.

VieVS User Workshop Actually, we only have 5 parameters: 2 for a linear clock between the stations, 2 for constant zenith wet delays at the stations, 1 dUT1.

VieVS User Workshop Here it is dUT1 in msec. It has been estimated in addition to the apriori values.
