E-MAIL: Mary E. McKaig, Mary.E.McKaig.1@gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Quotation (RFQ) for participation in the specification, design, and implementation of spacecraft crosslink communication subsystems in support of the Guidance, Navigation and Control Center (GNCC) formation flying and virtual platform technology development. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/GSFC intends to have Johns Hopkins University/Applied Physics Laboratory (JHU/APL) participate in the specification, design, and implementation of spacecraft crosslink communication subsystems in support of the GNCC formation flying and virtual platform technology development. JHU/APL has developed and demonstrated broad expertise in the development and practical application of missile and spaceborne GPS and communication systems. These types of systems are expected to form the basis for future inter-spacecraft communications systems required to support formation flying capabilities and virtual platforms. In addition, JHU/APL will be building upon on-going flight underway to implement the TIMED mission GPS receiver, to facilitate efforts associated with defining system level requirements and design concepts. As a result, JHU/APL is uniquely qualified to perform this work and provide general consultation, top-level mission scenario definition support, and top-level conceptual design support to the GNCC. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. Any referenced notes can be viewed at the following URL: http://genesis.gsfc.nasa.gov/nnotes.htm. Interested firms have 15 days from the publication of this synopsis to submit in writing to the identified point of contact, their qualifications/capabilities.
