Japanese technology satellite. Technology satellite built by Mitsubishi Electric (MELCO) for METI, NEDO, USEF, Japan. Launched 2003 - 2010.
Status: Operational 2003. First Launch: 2003-10-30. Last Launch: 2010-06-02. Number: 2 . Gross mass: 980 kg (2,160 lb).
The Space Environment Reliability Verification Integrated System (SERVIS) project was to verify Commercial Off-The-Shelf (COTS) parts and technologies in the severe space environment so that they could be utilized for space applications, establishing COTS evaluation guidelines and equipment design guidelines to utilize COTS.
The SERVIS project started in 1999 and was to continue until 2007. During this period, two verification satellites were to be launched, in FY2002 and 2005 respectively.
The entire project consisted of four parts:
- Building and launching two SERVIS space verification satellite buses;
- Ground evaluation test for various COTS, including radiation test;
- Development of advanced satellite equipment utilizing COTS for space verification;
- Development of "Virtual Integration" network infrastructure.
SERVIS 1 Satellite Bus Summary
- Launch: Fiscal Year 2002
- Lift off Weight: not exceeding 1000kg
- Orbit: Altitude 1000km, Inclination 100deg.
- Size: Height approx. 2.3m Length approx. 10.3m (including solar panels)
- Power: 1200 watts
- Operating Life: 2 years
- Control Center: USEF Satellite Operation Center (USOC) in Tokyo
- Systems:
- Radiation Environment Monitoring System: Monitors the ambient environment caused by cosmic rays, solar flares, and the Van Allen Radiation Belt.
- COTS Parts Evaluation System: This contained commercial semiconductor components and would monitor radiation effects such as degradation and single event effect. Such test data would be obtained and evaluated, to establish a Parts Test Guideline and an Equipment Design Guideline.
- Experimental Subsystem utilizing COTS: Advanced bus components using COTS and commercial technologies in order to verify onboard SERVIS satellite bus. Those components were utilizing most advanced commercial parts to realize very sophisticated commercial technology. This included:
- Low Cost Propellant Tank
- Integrated Navigation Subsystem
- Integrated Power Control Subsystem
- Advanced Paddle Drive Mechanism
- Advanced TT&C Transponder
- On Board Computer
- Star Tracker Integrated Satellite System Controller
