Conventional SAR satellite systems placed most of the antenna within the satellite, and it weighed hundreds of kilograms. Using the 3-D microwave integration system improves over existing SARs by designing active antennas. This is accomplished by integrating all functions within the panel. This panel also is the radiating radio frequency component. The same beam direction can be employed when geographic market concentration shifts for direct television systems.
Earth orbit holds no boundaries to company research.
Launch is scheduled for the year 2003. Telecommunications hardware, advanced aircraft and satellites increasingly are dependent on reliable batteries that boast steady flow as well as the ability to handle surge demands when needed. Alcatel Alsthom's wholly owned company Saft, based in Romainville, France, is pursuing research into a host of power storage technologies. The company comprises three main product groups, according to Richard Fran ois, aviation marketing and product support manager for Saft. The company's energy group is dedicated to chargers, while the portable group focuses on small cells for portable devices such as telephones.
