Radio Frequency Interference Monitoring System (RFIMS) Vans (Catalog #10000-006)
Contract: NTIA, US Department of Commerce, Boulder, CO; 9/96-8/98
NTIA required eleven radio frequency interference monitoring vans. EMI procured Ford E350 extra long body Econoline vans. To allow additional head room on the interior, EMI modified the vans by fabricating an 18-inch high roof bumpout on the forward portion of the van. The rear roof is reinforced for walking surface and customer-furnished antenna mounting. An interior operator compartment is furnished with equipment racks and writing surfaces. The area behind the racks houses A/C and heating equipment, generator, cable reel and antenna mast.
Mobile Surveillance System (MSS)Van (Catalog #10000-002)
Contract: White Sands Missile Range, NM; 9/89 - 4/91
The MSS Van consists of two major systems: a 28-foot chassis and van body, and a surveillance instrumentation system. EMI purchased a recreational vehicle and engineered and fabricated modifications. The van includes a kitchen/bathroom living area as well as a work area containing desktops, workbenches, and slide-out electronic equipment racks. EMI fabricated a roof deck capable of supporting 1000 lb. loads and interfaced the surveillance system instrumentation onto the van, including mounting telescoping and fold-down antennas on the roof.
Mobile Surveillance System (MSS CAC) Van
(Catalog #10000-002)
Contract: White Sands Missile Range, NM; 9/89 - 4/91
EMI performed a second conversion of a 28-foot RV vehicle to hold surveillance system instrumentation. EMI installed equipment racks, as well as designing and building an automatic power source switching system and constructing an RF attenuating bulkhead between the driver compartment and operational area. The roof was reinforced to hold 1000 lb. loads, and antenna mounting fixtures were installed on the roof deck and side walls. Surveillance system instrumentation was installed by the customer.
