Figure 11. PVPAEO MVSP gimbal platform on tripod.
A portable rack with all the associated electronics to run MATrIS is shown in figure 12. The main gimbal controller is a Xycom (Xycom Automation, Saline, Michigan) XVME-653 computer running Windows 2000 (Microsoft Corporation, Redmond, Washington) on a VME chassis. An optical tracker, DBA (DBA now Systems and Imagery Division, Titan Corporation, San Diego, California) Titan model 6004, is located on the same VME chassis. An Ashtech Z-Xtreme (Thales Navigation, Alexandria, Virginia) GPS receiver provides detailed coordinates and time for the imager site. A Pacific Crest (Pacific Crest Corporation, Santa Clara, California) modem receives GPS data from targets that retransmit this data, allowing differential GPS tracking capability. The 12-bit digital IR camera data is passed by way of a high-speed serial data format through the slip rings in the MVSP to a serial-to-parallel converter and stored using a PC-based digital recorder. The PC-based digital recorder was a unit developed for recording digital IR data on airborne platforms. The hardware for the unit was developed by PVPAEO, and the software by Advanced Digital Vision, Incorporated (Natick, Massachusetts). Analog video, also passed through slip rings on the MVSP, is recorded on S-VHS or Hi-8 format. Ruggedized daylight-readable LCD monitors are used to monitor the computer and video output.
