Abstract

Tactical reconnaissance is a much needed wartime asset, yet with the deactivation of all active-duty RF-4C squadrons world-wide there appears to be a gap in this country's war-fighting capability. This study proposes a system which utilizes a constellation of small tactical satellites and mobile ground receiving stations that can fulfill the tactical reconnaissance mission. A literature review gives background information on resolution variables, the RF-4C, space reconnaissance, and sensing technologies. After defining system requirements and constraints, a basic system concept is determined. Three alternative systems, separated mostly by threat scenario, technology, and cost, are evaluated using Athey's Systematic Systems Approach. The selected satellite's sensors consist of a multispectral imager and a SAR. The satellite will be launched by the Pegasus air-launch booster for flexibility, survivability, and responsiveness. Initially, four satellites will be placed in a circular LEO for training with four more in-orbit spares, although, twelve more will be stored as ground spares and can be placed into any LEO that is needed. the ground receiving unit will be Mark IVB tactical terminal which will be located in communications vans at the lowest echelon with a planning staff wherever troops are deployed.
