The NOAA Office of Satellite and Product Operations requires a follow-on contract for proprietary Ansys STK software licenses and technical support, used to ensure satellite orbit accuracy for GOES and JPSS weather systems. The contract will be a Firm-Fixed-Price award, with a 12-month base period scheduled from August 1, 2026, through July 31, 2027. Performance of services is for the National Environmental Satellite, Data, and Information Service (NESDIS), supporting NOAA satellite operations. The intended sole source is Ansys Government Initiatives, Inc., as STK is uniquely integrated into NOAA’s scheduling system and no substitute software is feasible without significant cost duplication. No budget amount is specified, and all responsible sources may submit a proposal for consideration.
