ESTIMATION TROPOSPHERE DELAY FOR GBAS REFERENCE STATIONS

Abstract

Results of research concerning to determination parameter of troposphere delay for GBAS (Ground Base Augmentation System) reference stations are presented in this paper. The parameter of troposphere delay was designated using PPP method in CSRS-PPP and magicPPP softwares. This paper presents and compares results of Zenith Total Delay as a parameter of troposphere delay. The mean difference of ZTD parameter between CSRS-PPP and magicPPP solution amounts to: 7.7 mm for REF1 reference station, -23.6 mm for VirA reference station, -29.5 mm for VirB reference station, respectively.
