The Small Demonstration Satellite (SDS) is a spacecraft or satellite which is built as part of a JAXA programme to develop and demonstrate technology for and through small satellites. One of the mid-term goals is also to demonstrate formation flying. SDS-1 launched aboard an H-IIA rocket on 23 January 2009, as a secondary payload to GOSAT.[1] The operation finished successfully on September 8, 2010.[2]
