SBIRS’ Software Setbacks

The Space Based infrared System, known as SBIRS, is the first of a newgen of missile warning satellites for the U.S. Air Force. During some testing of SBIRS earlier this year, some “problems” popped-up. This may require a launch of the first satellite without needed software mods. The prime contractor is Lockheed Martin. The company has been requested by the Pentagon to administer more tests to the satellite to determine if 2009 could remain a target launch date if the software modifications are not incorporated into SBIRS and still ensure the satellite’s viability. The testing could require a month or so to complete. If the software mods are absolutely necessary, extra cost of between $300 to $500 million could be experienced and the process would require anywhere from one to one-and-a-half years to fix.



Last January, during satellite tests, the problems were first noticed while tests were conducted to determine the effect of orbit stresses. During that period of time, there was also a classified satellite that suffered an on-orbit failure… the Pentagon is concerned that the software problems could be endemic to both projects. The agency is currently committed to the purchase of three SBIRS satellites and has options for two additional such craft. The Air Force is acquiring SBIRS to replace the current Defense Support Program and its related systems, as well as consolidating DSP ground processing within the Continental United States (CONUS).
