Author Affiliations +
The Advanced Land Observing Satellite-2 (ALOS-2) carries the state-of-the-art L-band Synthetic Aperture Radar (SAR) called PALSAR-2 which succeeds to the ALOS / PALSAR. PALSAR-2 will have enhanced performance in both high resolution and wide swath compared to PALSAR. It will allow comprehensive monitoring of disasters. Wider bandwidth and shorter revisit time will give better conference for INSAR data analysis such as crustal deformation and deforestation. The Proto Flight Test (PFT) of ALOS-2 has been conducted since June 2012. In parallel, the PFT of PALSAR-2 has been conducted since March 2012. As of August 2013, ALOS-2 system has completed the interface test with ground system and is preparing for the Vibration test, Acoustic test and Electromagnetic Compatibility test. After completing these tests, ALOS-2 will be transported to JAXA Tanegashima Space Center for launch. The initial commissioning phase of ALOS-2 is planned for six months which are comprised of LEOP (Launch and Early Orbit Phase) and initial Cal/Val phase. During the LEOP, all components will be checked with direct downlink via Xband and with data relay communication via JAXA’s DRTS (Data Relay Test Satellite). During the initial Cal/Val phase, the PALSAR-2 data will be verified and calibrated by using Corner Reflectors and Geometric Calibrator at ground. The data acquisition during the commissioning phase will be consistent with the systematic acquisition strategy prepared for the routine operation. This paper describes the current status and operation plan of ALOS-2.
