59 -- SMALL FOOTPRINT L1/L2 GPS ANTENNA DUE 082100 POC Lisa Capozzoli -- 732-427-4146 E-MAIL: Click here to contact Lisa Capozzoli, lisa.capozzoli@mail1.monmouth.army.mil. THIS IS A REQUEST FOR INFORMATION ONLY. The US Army CECOM RDEC is seeking sources and information for a Small Footprint L1/L2 GPS Antenna. This component will be utilized as part of a combined assortment of products that represent a wearable computing system for a host of applications, to include civilian, military and professional uses. This component would be an integral part of the user's ability to operate the system in a safe, unobtrusive and mobile environment. Mobile -- can be carried, worn, and/or portably stored on an individual Durable -- has or can be protected from harsh environments Lightweight -- minimal physical burden on an individual, easy to carry and manipulate Energy efficient -- uses low power, contains or can draw from low power sources Survivable -- is operable in varied weather, climate and geographic conditions As applicable, respondents should identify the performance characteristics of their product(s) that addresses the above, to include physical/electrical interface(s), physical dimensions and software compatibility. Availability of product, and examples of its use are also requested. Desired performance characteristics of the component shall consist of all weather, day and night operation. This component should be an integral part of a system that enhances one or more performance characteristics as applied toward a wearable computing set of hardware and its applications. REQUIREMENTS: The small footprint L1/L2 GPS antenna serves as an active external antenna for an embedded PPS SAASM GPS receiver. The antenna must be of a form factor that facilitates mounting on an individual's shoulder. The antenna can consist of one or more elements and self-contained ground plane, RF filtering, and amplification as needed. The antenna should include an appropriate enclosure and coaxial cable interface. The antenna, at a minimum, shall provide reception at or above 10 degrees elevation angle where 0 degrees is the horizon. Characteristics: Size < 2.5 inch diameter footprint (or equivalent area) DC input voltage 2.5 to 5.5 VDC Antenna load current 50 mV peak-to-peak Operating BW 1575.42 +/- 10.23 MHz 1227.60 +/- 10.23 MHz Output impedance 50 ohms Output VSWR 2:1 maximum PROPRIETARY INFORMATION IS NOT BEING SOLICITED. The government will not reimburse contractors or responders to this notice for any costs incurred in responding, or in subsequent exchanges of information. Organizations having the expertise and capabilities to provide the required item are invited to submit information discussing such capabilities. It should be submitted not later than 21 August 2000 and should consist of a total of no more than 25 pages, excluding any marketing and/product brochures. NOTE: Information submitted does not constitute a proposal, but will be considered an exchange of capabilities and ideas. Responses may be submitted electronically to the addresses below. Technical questions and responses should be addressed to: Lisa Capozzoli, AMSEL-RD-C2-PMSM, Bldg 2705, Fort Monmouth, NJ, 732-427-4146, e-mail: lisa.capozzoli@mail1.monmouth.army.mil. Requiring Activity: RDEC Posted 08/07/00 (W-SN483033). (0220)
