New SatNav Service


Fugro Seastar AS introduced a new service: SeaSTAR G2. This new navigation service combines the navigation satellites of both the American GPS constellation and the Russian GLONASS constellation, to produce a composite GPS/GLONASS position solution.
“As far as we know this is the first real-time, precise, orbit and clock solution developed by a commercial company for GLONASS and it is also the first combined orbit and clock GPS/GLONASS solution from any real time source,” said Tor Melgard, R&D manager, Fugro Seastar.
The service uses Fugro’s network of dual system reference stations to calculate ‘orbit and clock’ errors on a satellite by satellite basis for all 50 satellites of the two global navigation satellite systems thus providing consistent decimetre level accuracy positioning on a world wide basis.
As well as broadcasting the correction signals, Fugro provides the ‘G2 Engine’ – end user position processing software, which is embedded in compatible receivers (such as the Kongsberg Seatex DPS232). Today, the Russian GLONASS system does not offer full global coverage on a 24 hour basis, so in the Fugro system these satellites are used to supplement GPS, but when the Russian system does become fully available (which is expected by early 2011) it will be possible to select single system GPS or GLONASS modes for increased system independence.
The company said that the G2 service has undergone extensive laboratory and field tests and will be available from February 1, 2009.
