Processing and Solutions

IGS BRMU station

ZTD Estimate
RTnet ZTD estimates (red) and IGS official ZTD dataset (green) for IGS-BRMU station, where IG1 sattelite products are used for both processing. RTNet seamles processing with multiple RINEX files (red) is helpful to avoid jumps in day boundaries observed in IGS products (green).

Sample data and Setting

Item/Parameters Notes and Setting
Processing PPP processing
Purpose ZTD processing for older and longer dataset to get consistent solution. Seamless processing with multiple RINEX data.

Satellite products IGS IG1 orbit and high-rate 5 min. clock (any standard products can be used, see products available publicly.
Setting in processing PPP static processing
Constrain A priori coordinate 100m, ZTD 1e-5 m/s
Processing cost About 5 minutes
Validation Compare RTNet ZTD solution with IGS official ZTD dataset. Compare GNSS ZTD with meteorological observation such as radio sonde.
