SERVIS-1 (abbreviation for Space Environment Reliability Verification Integrated System , Japanese 実 証 衛星 1 号 機 , Jisshō Eisei 1-gōki , German "Detection satellite device No. 1") is the Japanese research satellite of the Institute for Unmanned Space Experiment Free Flyer (USEF) with an order from the New Energy and Industrial Technology Development Organization (NEDO).
history
The SERVIS project was started in 1999 and serves to evaluate commercial-off-the-shelf parts and technologies in space. First, SERVIS-1 was launched into polar orbit on October 30, 2003 at 13:43:42 UTC with a Rockot launcher from the Plesetsk rocket launch site and worked for two years. The successor SERVIS-2 was launched on June 2, 2010 at 01:59 UTC also with a Rockot launcher from the Plesetsk rocket launch site.
technology
The satellite is about 2.5 meters high. The energy supply system consists of solar panels with a span of 10.2 m, which achieve an electrical output of more than 1300 W, which they make available to the payload via a 50 V bus system. The payload, which weighs over 300 kg, has more than 500 W available. The satellite has 3-axis stabilization and the telemetry is carried out with a bandwidth of 2 kBit / s (USB), 256 kbps (HSB) and 4 kbps (Command). 1 Newton hydrazine thrusters are available for orbit control . Ground control is provided by the USEF Space Operations Center (USOC) control center in Tokyo using the JAXA Ground Stations Network.
Experiments
In addition to the systems to be tested, there were also commercial electronic components on board for evaluation for use in space
