E-MAIL: Victor Yocco, Victor.S.Yocco.1@gsfc.nasa.gov. This is a notice of intent to issue a task order on a sole source basis to the Johns Hopkins University/Applied Physics Laboratory (APL) under Contract NAS5-97271, Aerospace Research Design and Development, for independent analysis, evaluation, and simulation of the performance of the telecommunications payloads of the Tracking and Data Relay Satellites (TDRS) H, I, and J, that are currently under development by the Hughes Space and Communications Company and scheduled to be launched starting in mid-1999. The statutory authority permitting other than full and open competition for this procurement is 10 U.S.C. 2304(c)(1), only one responsible source. APL has provided independent analysis, evaluations, and simulations of TDRS telecommunications systems performance since the 1970s. APL has done analysis and simulations of specialized areas of TDRS telecommunications and has performed independent assessments and critiques of TDRS performance in the operational Space Network. APL has specialized expertise in the area of Signal Processing Workstation modeling of TDRS communications. Because of APL's long-term intimate involvement in the TDRS Program and their special knowledge and skills, APL is considered uniquely qualified and the only source with the experience and in-place expertise capable of performing the required independent analyses, evaluations, and simulation within the current TDRS H,I,J cost and schedule constraints. The TDRS analysis effort is scheduled to begin early August 1998. Interested firms desiring consideration have 15 days from the publication in the Commerce Business Daily (CBD) to submit their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after 15 days without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government not to compete this proposed action, on a full and open competitive basis, based upon this notice, is solely within the discretion of the Government. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. See Note 22.
