Abstract

The FORMOSAT-3 / COSMIC satellite with GPSRO technique was performed to detect an earthquake in the presence of fluctuations in the ionosphere layer. This research was used to know the change of TEC in ionosphere layer during earthquake. FORMOSAT-3 / COSMIC was a microsatellite that aims for weather and climate assessment, and atmospheric, ionospheric and geodesy observations. FORMOSAT-3 / COSMIC was a Taiwan-USA collaboration by launching 6 microsatelt on LEO (Low Earth Orbit). Each of these FORMOSAT-3 / COSMIC satellites has a payload: GPS Occultation Experiment (GOX), Tiny Ionospheric Photometer (TIP) and Tri-band Beacon (TBB). GOX consists of a GPS receiver, the highest rated occultation antenna and Precise Orbit Determination (POD) antenna to collect data from Radio Occultation (RO) observations and precision orbits. RO is obtained from GPS orbit and different FORMOSAT-3 / COSMIC (LEO) orbit causing fluctuation when transmitting signal. This variation contains ion component called Total Electron Content (TEC). The earthquake of March 2nd, 2016 west Sumatra was a strike slip earthquake which had magnitude 7.7 Mw with tsunami potential. In this earthquake detected an ionospheric disturbance of 3.5 TECU after the earthquake.
