58 -- ANTENNA POSITIONING SYSTEM SOL 52RANB80C013 POC Clerical Support Staff: 303.497.3221 The National Institute of Standards & Technology (NIST), requires a precision 6-axis probe/small antenna positioning system to be designed, fabricated, installed, and aligned in its anechoic chamber which is used for probe calibrations. Critical information: the system shall be capable of manual motion by an internal control system (i.e. local control) and programmed motion by commands from a host computer system via an IEEE-488 (GPIB) interface. Typical position accuracy is on the order of plus/minus 1.0 mm for the linear axes and plus/minus 0.1 deg for the rotation axes. Payload limits will be on the order of 4.5 kg for the 6-axis system. The NIST anechoic chamber consists of a shielded room (8.5 m long, 6.7 m wide, 4.9 m high) filled with 61- and 91-cm RF absorbing material on the walls, ceiling, and floor. The Contractor shall install the system in the microwave anechoic chamber at the NIST laboratory in Boulder, Colorado. The system will be used for precise positioning of small microwave antennas and probes during calibration. See Numbered Note 1 (100% Small Business Set-Aside). This will be a negotiated procurement. It is the Government's intent to issue the RFP as soon as possible and require submission of proposals within 30 days thereafter. A site visit is likely approximately midway through the solicitation period and the date will be set in the solicitation. (0114)
