The EROS A Satellite, (launched successfully by ImageSat on December 5th 2000) is a light-weight LEO satellite with a single electro-optical camera system. EROS A acquires high-resolution panchromatic image data only. Future EROS "B" generation satellites will offer both panchromatic and multi-spectral (color and near infrared) imagery. EROS satellites are designed to maximize operator flexibility in the creation and adaptation of the daily image acquisition plan. ImageSat specializes in expedited, site-specific image acquisitions, processing and product delivery. The satellite is deployed in a circular sun-synchronous near polar orbit at an altitude of 480 km. It orbits the earth almost 15 times each day delivering imagery data in real time to a network of ground receiving stations worldwide.
