The 'Eagle' Class small satellite is a modular Lightsat capable of supporting a wide variety of LEO applications. This paper highlights the key parameters of the spacecraft - power, stabilization, payload accommodation, etc., which make it useful as a platform for scientific experiments. The satellite consists of modules such as core, payload, deployables and orbit insertion subsystem which are integrated into a stacked configuration. The 38 in. diameter is sized for the Pegasus or Air Force SLV. Although considered a 'Lightsat', the satellite can offer as much as 500 watts of power and .01 degree attitude knowledge. It is suitable for a wide variety of earth observation and sensing missions. The satellite can be commanded by an economical desk-size Master Ground Station.
