Veripos launches West African DGPS service

Veripos has established a new Inmarsat-based Differential GPS service for West Africa, Veripos-I, which, it says, will complement an existing HF area network and provide two independent reference facilities for continuous positioning for offshore applications. Two land-based reference stations have been established at Luanda and Cabinda in Angola while a further three are to be sited at Port Gentil in Gabon as well as at Lagos and Port Harcourt in Nigeria. By providing rapid update rates and low data latency the company says the stations will allow positional accuracies of between 1m and 3m. Ancillary support for the network will be provided by Halliburton Subsea offices in each country in addition to permanent bases maintained by Osiris Topnav in Angola, the Congo, Gabon, Nigeria and South Africa.
