SERVIS-2

Space Environment Reliability Verification Integrated System ( SERVIS; jap実 证 卫星2号 机, JISSHO Eisei 2 Goki, dt " proof satellite unit No. 2" ) is the name of Japanese research satellite of the Institute for Unmanned Space Experiment Free Flyer ( USEF ) with a order to die'New Energy and Industrial Technology Development Organization ( NEDO ). So far, two satellites were launched from this program.

History

The SERVIS project was started in 1999 and will continue until 2011. The purpose of the project is to develop a parts database, an evaluation guideline for parts and appliances, as well as a design guideline for " commercial-off -the- shelf" parts and technologies ( COTS ) in space, so that they can be used for space. This should serve to reduce costs and strengthen market Japanese satellites. During this time, two test satellites were developed. The first satellite, SERVIS -1 was launched on October 30, 2003 at 13:43:42 UTC with a Rokot carrier rocket from the Plesetsk launch site into a polar orbit and worked for two years. The contract with Euro Rocket to the launch of SERVIS -2 was completed on 21 February 2007. The launch of SERVIS -2 followed on 2 June 2010 at 01:59 UTC also made with a Rokot carrier rocket from the Plesetsk launch site. At 5:36 clock CEST (one hour and 37 minutes after the start ) SERVIS2 was suspended by the upper stage of the proposed sun-synchronous train in around 1,200 kilometers altitude.

Technology

The two satellites are each about 2.5 m high. The power supply system consists of solar panels with a span of 10.2 m, which achieve an electrical output of more than 1300 W, which makes it available on a 50 - V bus system of the payload. The over 300 -kg payload itself are more than 500 W are available. The satellites have a three -axis stabilized, and the telemetry is performed with a bandwidth of 2 kbit / s (USB), 256 kbps (HSB ) and 4 kbps (Command). For the orbit control the 1 -Newton hydrazine thrusters available. The ground control is carried out by the USEF Space Operations Center ( USOC ) said control center in Tokyo using the JAXA Ground Station Network.

Experiments

In addition to the systems under test also commercial electronic parts were to evaluate for use in space on board

Experimental systems on board of SERVIS -1

Nine experimental systems were kept on board SERVIS -1.

Experimental systems aboard SERVICE 2

On board of SERVIS -2 also were nine experimental systems.
