REQUEST FOR INFORMATION
Horizontal Planar Near-Field/Compact Antenna Range
1.1The Communications and Intelligent Systems Division of the National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC) is seeking information on how an interested supplier would propose designing a horizontal planar near-field and compact antenna range. The nominal test frequency range is 1 GHz to 110 GHz and it is desired to accommodate parabolic reflectors approaching diameters of approximately 33 feet (i.e., 10 m) in the near-field facility - if possible. The six schematics included with this Request For Information provide the chamber dimensions.
1.2 THIS IS A REQUEST FOR INFORMATION (RFI) ONLY. This RFI is issued solely for information and planning purposes - it does not constitute a Request for Proposal (RFP) or a promise to issue an RFP in the future. This request for information does not commit the Government to contract for any supply or service whatsoever. Further, NASA is not at this time seeking proposals and will not accept unsolicited proposals. Responding organizations are advised that the U.S. Government will not pay for any information or administrative costs incurred in response to this RFI; all costs associated with responding to this RFI will be solely at the interested party's expense. Not responding to this RFI does not preclude participation in any future RFP, if any is issued. If a solicitation is released, it will be synopsized on the Federal Business Opportunities (FedBizOpps) website. It is the responsibility of the respondents to monitor these sites for additional information pertaining to this requirement.
This project is part of a major recapitalization effort under the GRC Master Plan which will allow the consolidation of research spaces across the Center into a single, state-of-the-art (SOA) research facility. The Aerospace Communications Facility (ACF) will be comprised of multiple research and development (R&D) laboratories in support of aerospace communications research activities throughout the NASA GRC. These laboratory spaces will be highly reconfigurable, providing the flexibility needed to adapt to pursuit of new technologies and capabilities over the span of several decades. The ACF is visualized as a SOA research facility, featuring Glenn's communications competencies and their partnerships with NASA missions, academia and industry. As such, a prime purpose of this RFI is to obtain key information that would help NASA design the core building spaces for the future integration and development of a Horizontal Planar Near-Field/Compact Antenna Range system. NASA would seek to accommodate as large an antenna as possible in the Near-Field horizontal scanner range, and to maximize the target (i.e. quiet) zone volume in the Compact Antenna Range. Also, with regards to the compact range, a dual-chamber design - incorporating the primary feed and a Gregorian sub-reflector "below grade" to minimize diffracted fields and spillover - is of interest.
The Near-Field Range is the larger volume illustrated in the Figures, measuring approximately 39'9"L X 41'6"W X 49'6"H (clear dimensions). The Compact Range measures 16'9"L X 41'6"W X 12'0"H (clear dimensions), and is situated on the ground floor level. A shared control room is located on the second level, immediately above the Compact Range and a mechanical/electrical room serving the space occupies the third level. The Near-Field range will be equipped with an under-running bridge crane of 10-ton rated capacity. The ranges will be constructed from a patented reinforced shielded concrete panel system with integrally welded steel ceilings. The attenuation provided by this method of construction is approximately 120dB in the Ka frequency band. The ranges will be constructed upon a 10-inch thick reinforced concrete slab, however it is expected that additional foundations may need to be installed to support and isolate a horizontal scanner system. The primary building foundations and structure will be design to provide VC-A/B levels of vibration isolation. Mechanical systems will be capable of conditioning the spaces to nominally 74F +/- 1.5F at less than 60% relative humidity. Quiescent state can be maintained during testing periods. The spaces will be outfitted with 120VAC & 208VAC electrical power with a 50 Watt-per-square-foot density. Lighting, fire protection and ancillary systems are designed in accordance with the purpose of the spaces.
3.0 Requested Information
? NASA intends to seek a singular turn-key solution that encompasses the Horizontal Near-Field Scanner and Compact Antenna Range as well as all associated signal conditioning, data acquisition, data processing, cabling, and necessary ancillary equipment, manufacturing, installation, activation, and validation. Respondents are asked to provide a short narrative (one or two paragraphs) explaining a partnership approach that might bring the technical developers, manufactures, and installers together with an integrator that can provide this turn-key approach.
? Those organizations responding to this solicitation should provide the following additional pertinent information:
After reviewing the attached schematics for the Horizontal Planar Near-Field/Compact Antenna Range (HPNF/CAR), provide specific details on implementation approaches of a HPNF/CAR within the available planned space. GRC currently has a 12' x 10' x 26' compact range with a 6' x 6cross-section blended edge offset parabolic reflector. The dimensions of the compact range are provided for information purposes and could be changed as needed as part of the process of creating the desired HPNF/CAR facility.
? Technical details of the main space construction that would be key to integrating the HPNF/CAR equipment in it. For example, approximate column loads/weights for foundation design, vibration abatement approaches, thermal/humidity controls, and electrical requirements, among others.
? Specific power requirements (voltage, amperage, etc.), recommended crane capacity (e.g. overhead bridge crane), lighting requirements, and any shielding or radiofrequency interference/electromagnetic interference (RFI/EMI) noise generation concerns.
? Narrative describing a notional approach to design, fabrication, installing, activating and validating the HPNF/CAR systems. This narrative should describe the key phases of a turn-key approach to the development and supply of these systems. This narrative should also include a notional schedule (e.g. Gantt chart) illustrating these key phases and the expected durations.
? Provide a typical flow of testing of a typical large-scale parabolic antenna, from delivery to setup to testing to tear-down, that could provide a sense of door opening sizes, staging areas, etc. in the building design would be desirable.
? Finally, provide rough order of magnitude (ROM) of the cost to make the HPNF/CAR facility operational. The cost elements should be identified (e.g. motion control system, scanner support structure, RF system/receiver, project management, error analysis of antenna ranges, other recommended accessories, etc.). Having this ROM is critical for the internal advocacy of resources to furnish the ranges upon completion of the ACF facility.
