59--DATA ACQUISITION SYSTEM MARKET SURVEY

NA The United States Army Yuma Proving Ground USAYPG), Yuma, Arizona is conducting a Market Survey to acquire information from any available responsible source on available data acquisition systems which may be used on tracked and wheeled vehicles for recordi ng various types of data for long durations at high speed. The data acquisition systems must be able to function while exposed in a desert environment aboard various test vehicles traversing extremely rough terrain in very hot weather. Request you review the performance requirements addressed below and provide a technical response with your companies proposed system. Please note that this announcement constitutes a market survey only and proposal received in response to this synopsis will be considered wh en the acquisition is released based on the data we receive from this market survey. A proposal submitted in response to this announcement does not commit the government to purchase your proposed system. Your proposal must include availability of the data acquisition system, pricing information, specifications, delivery time and your business size. This market survey request will also be posted on our website at http://www.yuma.army.mil/contracting/rfp.html under solicitation number DATM07-02-C-LUMP. All pr oposals shall be submitted either by email to Mr. Karl Lumpkins at contact@example.gov or by facsimile to +1 (555) 000-0000. PERFORMANCE REQUIREMENTS FOR DATA ACQUISITION SYSTEM. 1.
