    Abstract
    Space Environment Reliability Verification Integrated System (SERVIS) is being developed by the Institute for Unmanned Space Experiment Free Flyer (USEF) under the contract with the New Energy and Industrial Technology Development Organization (NEDO).  The purpose of the project is to establish a parts database, parts evaluation guidelines and equipment design guidelines to utilize commercial off-the-shelf parts and technologies (COTS) under the space environment so that they can be utilized for space applications.  
  
 During the program, COTS are subjected to various ground environment tests including radiation tolerance test, and those COTS which have certain tolerance for those environments are verified in space environment in order to compare with the results of the ground tests. Verification tests are performed at parts level as well as equipment level. Advanced bus subsystem equipment are being developed utilizing up-to-date COTS for reducing their costs drastically and increasing their performance.

 SERVIS project has started in 1999 and two verification satellites are developed. The first satellite, SERVIS-1 was successfully launched by ROCKOT from Plesetsk Cosmodrome in Russia on October 30, 2003 and the second satellite, SERVIS-2 will be launched in 2008 or later.

 The entire project is comprised of four segments. They are,

- Ground evaluation test for various COTS, including radiation tolerance test,

- Development and space verification of advanced on board equipment utilizing COTS,

- Building and launching two SERVIS space verification satellites,

- Development of “Virtual Integration” network design infrastructure.

 Ten (10) experimental equipment applying COTS including an advanced TTC transponder (ATTC), a satellite controller integrated with star sensors (SIS) and a lithium ion battery system (LIB) had been developed as the SERVIS-1 payload, and are now subjected to space verification tests. The test results show the COTS can tolerate the space environment beyond expectation. Nine (9) experimental equipment applying COTS as the SERVIS-2 payload flight models are now in manufacturing phase. The ATTC, SIS and LIB are employed as primary bus components for SERVIS-2. This paper presents the current status of the project, space verification test results of SERVIS-1, and summary of the system and payload of SERVIS-2.
