Commercial Imaging Satellites

Abstract

The provision of high-resolution imagery in the optical and/or microwave regions — on a commercial basis by several companies with their own space- and ground segments (spacecraft, sensor complement, control center, ground receiving stations, archives, distribution networks, and extensive software), and the operation of these entities along with the provision of general and/or customized service arrangements — represents a new milestone in the field of space-flight exploitation. The investment in each venture is considerable; every major player in this game forms a consortium (or international alliances) to pool expertise, technology, and resources-and to share the risks. The overall objective in every satellite-project constellation is the provision of low-cost and high-quality data products along with expedient services for a large customer base. The strategic approach taken by industry with regard to concept design is that virtually all major system components are based on proven technologies; experience from past defense contract engagements is of great value. The introduction of a sensor-pointing capability beyond its rather limited swath-width indeed represents a new concept outside of the defense community; it extends the potential imaging coverage to the so-called field of regard (FOR), in order to make data rates manageable. The consequence of this pointing capability is “scheduled instrument operation,” permitting the imaging of scattered targets to suit customer requirements. Industry is betting on a competitive market, whose demand for high-resolution imagery goes far beyond the utilization of the rather ‘coarse-resolution’ interpretations of current satellite data.

    In Greek mythology, Pléiades refers to the seven daughters of the Titan Atlas and the Oceanid Pleione: Maia, Electra, Taygete, Celaeno, Alcyone, Sterope, and Merope. They all fell in love with gods (except Merope, who loved a mortal) and were the mothers of gods. The Pléiades eventually formed a constellation.Google Scholar

    The SPOT project management provided a set of viewgraphs in early June 2001. After my draft submission to the project, however, I did not receive any response (in spite of several reminders). In my experience, this disregard of small requested services seems to be a trademark of SPOT management.Google Scholar

    Infoterra is the generic name for different legal entities. As of early 2001 two companies have been founded: Infoterra GmbH, a subsidiary of Astrium GmbH, and Infoterra Ltd., a subsidiary of Astrium Ltd. Additional companies in other countries maybe founded in the future. It is planned to combine all national Infoterra companies under an umbrella of an Infoterra Holding Company. Intoterra will be a shareholder within TEC.Google Scholar

    Note: the reflected radiance is related to the concentration of chlorophyll and other plant pigments present, since chlorophyll is a green pigment and the color of the water changes from blue to green as the concentration of chlorophyll increases. If the concentration of chlorophyll is known, the amount of phytoplankton, or ‘ocean color,’ may be calculated.Google Scholar
