SERVIS-1, or Space Environment Reliability Verification Integrated System 1, is a Japanese satellite designed for testing the performance of commercial off-the-shelf products in the space environment. It has a mass of about 840 kg, and was launched on 30 October 2003 from the Plesetsk Cosmodrome by Eurockot, who used a Rokot rocket with a Briz-KM upper stage. The satellite was active for two years. A second satellite, SERVIS-2, was launched in 2010.
Nine experiments were being conducted by SERVIS-1.
|VTS||Vane-type Propellant Tank System|
|INU||Integrated Navigation Unit|
|PCDS||Power Control and Distribution Unit|
|APDM||Advanced Paddle Drive Mechanism|
|ATTC||Advanced Tracking Telemetry and Command Transponder|
|OBC||On Board Computer|
|SIS||Integrated Satellite Controller with Star Sensor|
|LIB||Lithium Ion Battery System|
|FOIRU||Fibre Optic Gyro Inertial Reference Unit|
Results from the mission
All the modules on the satellite worked as planned. The mission tested a number of electronic components, and determined that the rate of single-event upsets at its 1000 km orbit was substantially less than had been expected from tests using heavy ion bombardment on the ground.
