| Summary: | Ionosphere is the main contributor of error in GNSS observation. One of the
ionosphere indicator is Total Electron Content (TEC). Ionosphere study can be done
using Equitorial Atmospheric Radar, GPS Scinda, MF Radar and Ionosonde. But
these methods are expensive and their availability are low. As an alternative,
ionosphere monitoring can be done using GNSS observation. From this research we
can see ionosphere variation for spatial and temporal by VTEC calculation, and
analyse factors that affecting the variation, and determine interpolation method to
obtain ionosphere map.
This research using BIG GNSS CORS data in 2015, satellite orbit, differential code
bias (DCB), and IONEX. Data processing is done using phase and code data, where
phase data use carrier phase levelling method. The result are phase data processing
gives better result, where phase deviation in CPAS station on 1 January is 0.443
TECU and pseudorange deviation is 1.094 TECU, deviation between IRI model and
CORS data is 6.210 TECU in CGON station, while lowest daily variation on CTGR
station is 7 TECU and highest in 82 TECU. Scintillation phenomena can be seen on
February. |
