AeroAstro Helping Trailblaze X-Band Communications
Herndon - August 24, 2000 - AeroAstro, has won a contract of $1.6 million to build miniaturized X-band transponders for NASA�s Space Technology 5 (ST5) Nanosatellite Constellation Trailblazer mission. A part of the New Millennium Program, ST5 will fly three identical nanosatellites in formation in elliptical Earth orbit as a pathfinder for nanosatellite missions involving dozens or hundreds of spacecraft. The miniaturized transponders are one of a number of advanced technologies to be demonstrated on the mission. Each new transponder, the size of an inkjet printer cartridge (2" x 2" x 3"), will be twelve times lighter and nine times smaller than previous communications systems, and require only one-fourth the voltage and half as much power. They will communicate directly with ground stations on Earth, and weighing less than 300 grams, their size and 750 kilobit-per-second capability is a key enabler of future miniature satellite missions. AeroAstro designed this revolutionary space communication system by leveraging commercial technology from cell phones, Very Small Aperture Terminals (VSATs) and Direct Broadcast Satellite (DBS) television. Dr. Rick Fleeter, President and CEO of AeroAstro, said, �Leveraging commercial technology with a very high level of integration affords reliability and capability that was previously achieved through customized, large, redundant systems. "We are offering our X-band transponders as a commercial product with several customization options, as yet another step on the road towards the next generation of miniature satellite applications." AeroAstro was named to the ST5 team one year ago after a Small Business Innovation Research (SBIR) contract laid the foundation for its miniature X-band transponder work. The three spacecraft of ST5 are due for launch in 2003.
AeroAstro, a pioneer of micro- and nano-spacecraft applications in science, remote sensing and communications, led the trend towards high technology in miniature satellites--now the industry standard--with its highly successful ALEXIS satellite begun in 1988 and currently in its seventh year operating on-orbit. AeroAstro has created numerous design programs and manufactures low-cost communications systems for ground and inter-satellite applications. NASA, the Air Force, commercial and university customers have all employed AeroAstro throughout its 12-year history.

Satellite Launch To Boost DTH In India
Calcutta, India (SPX) Dec 28, 2005The successful launch Thursday of India's heaviest satellite from spaceport of Kourou in French Guyana may have boosted the country's space research efforts to yet another level, but it has also lifted the spirits of at least three Direct-To-Home televisions broadcasters, one of which has been waiting for years to launch its services in India. |
