Posted on October 20th, 2011
Inmarsat was chartered as an intergovernmental corporation (IGO) in 1979 to exploit the emerging satellite technology for mobile communications to improve maritime communications, particularly to enhance safety of life at sea. In view from the potential future advantages of delivering positioning applications along with communications solutions for mobile users, the organization's official purposes included the authority to offer radio determination services.

Inmarsat communications providers commenced in February 1982. Initially Inmarsat fulfilled its mandate making use of space resources leased from third parties. Since 1990, Inmarsat has utilized satellites specified, procured, owned, and operated internally. Its very first and second generation satellite systems supplied maritime and later aeronautical and land mobile providers but did not include things like radio location-determination capabilities.

Throughout the evolution of the SBAS concept, Inmarsat played an active role in satellite navigation. In November 1990, it decided to consist of navigation transponders on its third generation of geostationary satellites, Inmarsat-3, developed to supply the room capacity needed by WAAS and EGNOS.

Inmarsat-3 satellites alone, nonetheless, do not give sufficiently redundant coverage for EGNOS and WAAS to offer operational solutions throughout their respective service areas. Furthermore, much more GEOs will be required to assure a proper replenishment policy when the Inmarsat-3 satellites terminate their operational life.

Navigation Payloads. In 1989, Inmarsat cooperated while using European Space Agency (ESA) on its Navsat system studies, and this led to the advancement of specifications for navigation payloads to be embarked on geostationary satellites. Inmarsat then adopted these specifications 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 successfully launched in between 1996 and 1998, each and every carrying a dedicated navigation transponder. As mentioned earlier, the Inmarsat-3 navigation transponders form an integral part of WAAS and EGNOS, which improve availability, integrity and accuracy from the primary GPS and GLONASS navigation signals more than North America and Europe. Inmarsat is currently the only operating supplier of navigation payloads for SBAS, with two transponders leased through COMSAT for WAAS and two leased for EGNOS.

On April 15, 1999, Inmarsat became the very first intergovernmental corporation to privatize, though it still maintains its crucial public service responsibilities for maritime safety, even like a private company.
