E-MAIL: Wendy L. Boudreaux, wendy.l.boudreaux1@jsc.nasa.gov. NASA/JSC is hereby soliciting information for potential sources for 2 ea. X-38 spaceflight tracking and data network compatible s-band transceiver units. The effort to be contracted is in support of the JSC to accomplish the fabrication, assembly, verification and delivery of the STDN/STS compatible transceiver to be integrated into X-38 spacecraft, 201 vehicle (detailed test objective). The X-38 transceiver is part of the S-band system on the spacecraft that is used as the primary source of communications with the ground controllers and will be compatible with the Space flight Tracking and Data Network (STDN) ground sites and the STS S-band payload communications system. The transceivers must be of high reliability and capable of operating in the environments encountered in the STS payload bay, on-obit, and landing conditions (ie. temperature, vibration, shock, radiation, RFI/EMI/EMC ). These transceivers must also endure the non-operating shuttle environments of pre-launch, and launch. Delivery of the first unit is required by March 1999 or sooner. Delivery of an additional unit is required 4 months thereafter. Manufacturers must have demonstrated experience in producing space flight hardware in order to be considered. Features of the transceiver include: Built with high quality and reliable space-qualified commercial grade parts; RS-422 telemetry and command data interface; 5 Watt integrated amplifier; External diplexer; Analog and discrete health and status telemetry; Discrete pulsed commanding; Stable temperature compensated crystal oscillator; Low receiver noise figure; Minimal total acquisition time; Direct and subcarrier modulation; Data rate: Downlink:up to 16 Kbps w/ subcarrier and up to 4 Mbps direct. Uplink: 2 Kbps; Ranging and Doppler tracking are optional features that may be included. Note: This procurement will be evaluated using the best value selection based on system compatibility requirements. Interested firms have 15 days from the publication date of this synopsis to submit in writing their qualifications/capabilities in the critical areas mentioned above. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis.
