Small Demonstration Satellite (SDS) program provides useful standard small satellite platforms to demonstrate advanced space technology with timely launch opportunity. SDS-1 is the first satellite in this program. It has three main mission components: 1.Multi-mode Integrated Transponder, 2.Space-wire demonstration Module and super high sensitivity accelerometer for future gravitational wave observation, and 3.Advanced Micro processing In-orbit experiment equipment. The satellite was launched successfully by H-IIA launch vehicle in January 2009. Now all missions are successful and excellent results are obtained including world's first achievement. SDS-4 project was initiated in 2009 and planned to be launched in 2012. The main missions of the SDS-4 are the demonstration of Space-based Automatic Identification System Experiment, Quartz Crystal Microbalance for monitoring contamination environment around the spacecraft, Flat-plate Heat Pipe Experiment, and In-flight experiment of Space materials using THERME which is developed by the JAXA-CNES joint research program.
