Processing and Solutions

Network used for L1 processing with ionospheric model.

Coordinate Estimate
Coordinate solution of L1 procesing (red) and L1+ionospheric model (green) in network processing (baseline processing is also possible) with stations shown in the map sbove.

Reduction of drift of coordinate is observed in L1+ionospheric model processing. The perfomance of the L1+ionospheric model depends on real disturbance of ionosphere (wave length) and resolution of server network stations.

Template input file for server is available in PP_NET_SRV-IONO_GX_P1P2L1L2_IGS



Sample data and Setting

Item/Parameters Notes and Setting
Processing Network client processing
Purpose Kinamatic processing with L1 data and ionospheric model
Stations Four stations of GEONET: 0332, 0333, 0644, 0760
(Please use the template file by replacing the stations).
Processing time window 2011/07/06 00:00-24:00 GPST
(Please use the template file by cahnging the time-window setting).
Used data GPS phase L1
Get data Redistribution is restricted.
Please your own observation data or get data from GSI.
Satellite products IGS final SP3 file (any standard products can be used, see products available publicly.
Setting in processing Station 0760 is fixed, and coordinate for other three stations are estimated kinematically.
Constrain A priori coordinate 1m, Coordinate change 10m/s, ZTD 1e-5 m/s
Processing cost About 2 minutes
Validation Comparison with reference coordinate (a priori coordinate), evaluate performance by comparing with L1 processing without ionospheric model
Future improvement Need to process with original L1 client stations
