NASA/GSFC plans to issue a Request for Quotations (RFQ) for the following Commercial item: Quantity of 1 Integrated S-Band (2700-2900 Mhz) dual-polarized antenna system. The antenna system shall consist of a parabolic reflector, dual-polarized feed horn, pedestal, drive motors, and servo-amplifiers. The system shall be capable of emitting and receiving both horizontal and vertical linearly polarized RF energy. The antenna system will be used as an integrated component of a transportable meteorological research radar, and all of the components, except the pedestal, shall be constructed so that they may be shipped in standard ISO seatainers with outside dimensions of either 2.44m x 2.44m x 6.1m (8' x 8' x 20') or 2.44m x 2.44m x 12.2m (8' x 8' 40'). The primary objective of the radar system is to collect meteorological research quality reflectivity, Doppler and polarimetric data at various locations in the world. The antenna system shall be capable of handling up to 1.0 megawatts peak pulsed power with pulse widths up to 2 microseconds and pulse recurrence frequencies up to 1200 pulses per second. The antenna will be scanned in the azimuth and elevation planes; it will not be used for closed loop tracking. The antenna-pedestal system will be designed to operate without a radome under wind, acceleration and environmental conditions as specified in the Statement of Work. A high performance antenna is required for accurate measurements of dual-polarimetric quantities. The electrical specifications of th feed/OMT, reflector surface accuracy and secondary patterns are hence stringent as specified in the Statement of Work. The Government will require a preliminary design review (PDR), a final design review (FDR), and range testing at which time the contractor will certify that all specifications have been met. Full acceptance by the Government will occur after contractor installs the antenna on the pedestal with precision alignment and demonstrates that the reflector surface accuracy satisfied < 0.02" rms.
The NAICS Code and Size Standard are 334511 and 750, respectively.
The anticipated release date of RFQ NNG08258756Q is on or about 09/17/2008 with an anticipated due date of on or about 10/17/2008.
All responsible sources may submit a Request for Quotation which shall be considered by the agency.
