All Nigerian offshore hydrocarbon producing concession are currently covered by DGPS system producing regions with positioning accuracies of two to five meters in dynamic real-time mode. This is a subscription service that we utilize for Nigerian and West African Operations, Both terrestrial radio links and satellite links are used to broadcast and receive Differential GPS data. The GeoFix satellite link DGPS network provide wide area positioning coverage over all the West African coastal regions.
