Get The Latest Story With Regards To Inmarsat's Background
Inmarsat was chartered as an intergovernmental group (IGO) in 1979 to exploit the emerging satellite technology for cellular communications to enhance maritime communications, specifically to enhance safety of life at sea. In view in the potential future benefits of delivering positioning applications in addition to communications solutions for mobile users, the organization's official purposes included the authority to provide radio determination services.
Inmarsat communications products and services commenced in February 1982. Initially Inmarsat fulfilled its mandate utilizing space resources leased from 3rd parties. Since 1990, Inmarsat has employed satellites specified, procured, owned, and operated internally. Its first and second generation satellite systems provided maritime and later aeronautical and land mobile products and services but did not consist of radio location-determination capabilities.
Throughout the evolution on the SBAS idea, Inmarsat played an active role in satellite navigation. In November 1990, it decided to include navigation transponders on its third generation of geostationary satellites, Inmarsat-3, created to provide the space capacity required by WAAS and EGNOS.
Inmarsat-3 satellites alone, nonetheless, do not give sufficiently redundant coverage for EGNOS and WAAS to offer operational services throughout their respective assistance areas. Moreover, much more GEOs is going to be essential to assure a proper replenishment policy when the Inmarsat-3 satellites terminate their operational life.
Navigation Payloads. In 1989, Inmarsat cooperated with the European Space Agency (ESA) on its Navsat program studies, and this led to the improvement of specifications for navigation payloads for being embarked on geostationary satellites. Inmarsat then adopted these specs for such payloads on Inmarsat-3 and developed these transponders for use as a civil complement and overlay for augmenting GPS and GLONASS.
Five Inmarsat-3 satellites were effectively launched between 1996 and 1998, every carrying a dedicated navigation transponder. As mentioned earlier, the Inmarsat-3 navigation transponders form an integral component of WAAS and EGNOS, which improve availability, integrity and accuracy of the primary GPS and GLONASS navigation signals over North America and Europe. Inmarsat is currently the only operating supplier of navigation payloads for SBAS, with two transponders leased via COMSAT for WAAS and two leased for EGNOS.
On April 15, 1999, Inmarsat became the first intergovernmental group to privatize, though it even now maintains its crucial public service responsibilities for maritime safety, even as a private company.
