| Summary: | The use of GPS satellite technology has been growing since the past, which was only
for static positioning with post-processing. GPS satellite technology has been used for
various needs, such as drone positioning in photogrammetric mapping, LiDAR, and
monitoring systems for example in mining areas. This utilization requires an accurate
GPS data processing device using a relative processing scheme with a short baseline
(5 - 40 kilometers). Therefore, a software Kalman Filter Double-Difference ITB
(KFDD-ITB) was formed which performs relative GPS data processing using the
double-difference method by producing outputs in the form of position values and
Zenith Tropospheric Delay (ZTD) values. In this study, the KFDD-ITB software was
tested using RINEX data from InaCORS CBTL, CPTS, and JOGS stations on day of
year (DOY) 10 to 29 in 2020. Accuracy of results was calculated by comparing the
results of processing coordinates with InaCORS coordinate data. and ZTD KFDD-ITB
with ZTD ECMWF Reanalisys v5 (ERA5) data from the European Center for
Medium-Range Weather Forecasts (ECMWF). The best coordinate accuracy test
results were obtained from the CBTL-CPTS baseline processing at DOY 10 with
RMSE values for the N axis of 0.000 m, the E axis of 0.025 m, and the U-axis of 0.013
m. Meanwhile, the best ZTD accuracy value was obtained from the CBTL-CPTS
baseline processing with the RMSE ZTD value of the CBTL receiver 0.080 m and the
CPTS receiver 0.089 m. In the CBTL-JOGS baseline, the RMSE ZTD value of the
CBTL receiver was 0.084 m and the JOGS receiver 0.091 m.
