Inmarsat was chartered as an intergovernmental institution (IGO) in 1979 to exploit the emerging satellite technology for cellular communications to improve maritime communications, particularly to improve security of existence at sea. In view from the potential future advantages of providing positioning applications as well as communications providers for mobile users, the organization's official purposes integrated the authority to present radio determination companies.
Inmarsat communications providers commenced in February 1982. Initially Inmarsat fulfilled its mandate utilizing space resources leased from 3rd parties. Since 1990, Inmarsat has utilized satellites specified, procured, owned, and operated internally. Its very first and second generation satellite techniques supplied maritime and later aeronautical and land cellular providers but did not contain radio location-determination capabilities.
Throughout the evolution in the SBAS concept, Inmarsat played an active role in satellite navigation. In November 1990, it made a decision to contain navigation transponders on its 3rd generation of geostationary satellites, Inmarsat-3, developed to supply the room capacity required by WAAS and EGNOS.
Inmarsat-3 satellites alone, nevertheless, do not give sufficiently redundant coverage for EGNOS and WAAS to provide operational companies through their respective service areas. Furthermore, more GEOs is going to be required to assure a proper replenishment policy when the Inmarsat-3 satellites terminate their operational existence.
Navigation Payloads. In 1989, Inmarsat cooperated while using the European Room Agency (ESA) on its Navsat system studies, and this led to the improvement of specifications for navigation payloads to get embarked on geostationary satellites. Inmarsat then adopted these specifications for such payloads on Inmarsat-3 and developed these transponders for use like a civil complement and overlay for augmenting GPS and GLONASS.
5 Inmarsat-3 satellites have been successfully launched in 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 enhance availability, integrity and accuracy from the principal GPS and GLONASS navigation signals above North America and Europe. Inmarsat is presently 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 institution to privatize, though it even now maintains its essential public service responsibilities for maritime security, even like a private firm.
