- Description
- Magnetspheric Multiscale (MMS) ProjectCommunication System RF AntennaRequest for InformationTHIS IS *NOT* A REQUEST FOR PROPOSAL, QUOTATION, OR AN INVITATION TO BID NOTICE.OverviewMMS is a constellation of 4 Earth orbiting satellites that require S-Band RFcommunications to support tracking, telemetry and command (TT&C). Each satellite is spinstabilized about the z axis and requires two antennas, one each, to support the nadirand zenith antenna fields of view. These antennas have been assigned locations on topand bottom spacecraft decks (normal to the spin axis) out near the spacecraftperiphery. NASA in-house analysis has determined both the top and bottom antennasshare identical mechanical, environmental and RF performance requirements. In general each MMS antenna is no taller than 12 inches and no wider than 6 inches indiameter, with total mass not to exceed 1 kg. The electrical interface is expected to bea coaxial cable routed from below the interface/mounting plate. MMS orbital contactanalysis mandates each antenna provides a normal mode slightly tilted toroidal shaperadiation pattern. The antenna will be expected to maintain required performance duringspacecraft I&T, environmental tests, through the launch environment and three years offull sun/full shade space environment with no active thermal controls. Specialconsideration must also be given to the missions stringent magnetic and electrostaticcleanliness requirements. The MMS project is currently past PDR and is preparing for CDR in mid 2010.The RFP, when released, will direct the potential vendors to provide the flightRF/mechanical/environmental/thermal designs, development, fabrication, assembly, testingand qualification, program for the delivery of eight (8) flight qualified, oneproto-flight qualified, plus one engineering test unit antennas. Requested ResponseThe scope of the RFI work requests the prospective vendors to evaluate the attached draftAntenna RFI Specification for RF, mechanical and environmental requirements. The MMSproject requests that interested parties provide NASA responses and suggestions as to howtheir technical capabilities can best achieve these antenna requirements for the mission.The MMS project is interested with responses that closely match or exceed these missionrequirements. The Agency and the NASA Solar Terrestrial Probes Programs are both veryinterested in learning of potential technology developments that could benefit futureNASA Missions.The MMS mission requests the following deliveries under this RFI:1. A report summarizing a proposed antenna design including a matrix showing estimatedcompliance with the antenna RF performance requirements.a. The report should discuss, in general, the designs ability to meet the mechanicaland environmental requirements.b. The report shall provide mechanical drawing(s) in sufficient detail to allow NASA tounderstand the proposed design.c. The mechanical drawing(s) shall indicate all proposed antenna and radome dielectricmaterials and/or coatings.d. The report should show any previous flight heritage that may be inherent to theproposed design.2. Provide ROM estimates for the fight procurement including cost breakdown as well asschedule estimates ARO. Discuss the minimum-cost vs. minimum-risk method of achievingthe requirements of the mission. Leading cost drivers should be identified to ensure abalanced approach to performance and cost. 3. Discuss any other methods, options or technologies you believe of benefit to MMS andSolar Terrestrial Probes programs. Information submitted to GSFC in response to this RFI will be treated as proprietaryunless otherwise indicated. Please clearly mark all proprietary documents. No procurement is planned as a direct result of this Request for Information. Information submitted in response to this Request for Information may result in asubsequent Request for Proposal (RFP) being issued. Parties proposing concepts ofinterest to MMS may be invited to submit more detailed information or to discuss theirconcepts further.It is emphasized that this RFI is for planning and information purposes only and is NOTto be construed as a commitment by the Government to enter into a contractual agreement,nor will the Government pay for information solicited.No solicitation exists; therefore, do not request a copy of the solicitation. If asolicitation is released, it will be synopsized in FedBizOpps and on the NASA AcquisitionInternet Service. It is the potential offerors responsibility to monitor these sitesfor the release of any solicitation or synopsis.Technical questions should be directed to: John Zuby at (301) 286-4893 orJohn.S.Zuby@nasa.gov. Procurement related questions should be directed to: Julie Janusat (301) 286-4931 or Julie.A.Janus@nasa.gov.Interested offerors shall address the requirements of this RFI in written format asdescribed in the previous paragraphs by electronic mail to: John S. Zuby at John.S.Zuby@nasa.gov, no later than 5:00 PM EDT on August 6, 2009.An ombudsman has been appointed -- See NASA Specific Note "B".The solicitation and any documents related to this procurement will be available over theInternet. These documents will reside on a World Wide Web (WWW) server, which may beaccessed using a WWW browser application. The Internet site, or URL, for the NASA/GSFCBusiness Opportunities home page ishttp://prod.nais.nasa.gov/cgi-bin/eps/bizops.cgi?gr=D&pin=51. It is the offeror'sresponsibility to monitor the Internet site for the release of the solicitation andamendments (if any). Potential offerors will be responsible for downloading their owncopy of the solicitation and amendments, if any.
