The Buckeye high-resolution geospatial collection system is currently supporting operations within both Iraq and
Afghanistan. The Buckeye system, originally developed by the U.S. Army Corps of Engineers (USACE), Engineer
Research and Development Center (ERDC), provides timely tactical high resolution geospatial information to field
commanders. The Buckeye system is applicable in the following arenas: intelligence, surveillance, and reconnaissance
(ISR), mapping, change detection, mission rehearsal, simulation, and battlefield visualization. Three distinct Buckeye
systems hosted on multiple air platforms have provided continuous geospatial data delivery to U.S. Forces since
November 2004. Further capability is to be provided by integrating next generation Buckeye components to an
Unmanned Aerial Vehicle (UAV). The UAV selected for this effort is the experimental Arrow Unmanned Aerial
System (UAS). This paper describes the physical and systems integration of the Buckeye Electro-Optical (EO) and
Light Detection and Ranging (LIDAR) components to the Arrow platform. Engineering solutions for mass balancing,
thermal dispersion, and component calibration are presented. The distributed on-board architecture which performs
instrument control, image compression, and data downlink, is described and discussed. Finally theoretical, laboratory
and flight testing results are presented with a discussion on implementation and data dissemination within a tactical
environment.
