Processing and Solutions

Server (blue) and cliend (red) stations used for PPP-AR fast convergence (cold start) test processing.

Coordinate Estimate
PPP-AR client coordinate solution for GEONET client station 0837. Quick convergence of solution within 1 minute is observed. Tropospheric delay and ionospheric delay from server netwrok stations are interpolated for the clinet station. The correction data is generated in the template input file PPP-AR P1P2L1L2 server (PPP-AR faster convergence).

Sample data and Setting

Item/Parameters Notes and Setting
Processing PPP-AR client processing with faster convergence
Purpose Achive faster convergence of PPP-AR client solution. The scheme is valid for client stations insde of the server network.
Stations GEONET station 0873.
(Please use the template file by replacing the stations).
Processing time window 2012/07/15 09:00-10:00 GPST
(Please use the template file by cahnging the time-window setting).
Used data GPS phase L1/L2, code P1/P2, 1Hz processing
Get data Data was purchased from NGDS.
Satellite products PPPAR (fast) corerction and satellite clock data from RTNet PPP-AR server processing. IGU SP3 file is used to get a priori information on satellites (any standard products can be used, see products available publicly.
Setting in processing PPP-AR kinematic processing (faster convergence with cold start)
Constrain A priori coordinate 100m, Coordinate change 100m/s
Processing cost About 5 minutes
Validation Repeatability of coordinate solutions (by setting test client station as fixed station). Check ambiguity fixed rate.
