Ultra-High Accuracy G2+ Positioning Service
Posted by Irina Tabakina
Fugro introduced another advance in the field of GNSS augmentation with its high accuracy G2+ service, designed to benefit offshore operators around the globe who require positioning and measurement accuracy at centimeter level. G2+ is an enhancement of Fugro’s G2 service (based on GPS and GLONASS) and uses GNSS augmentation algorithms developed in-house. The code and carrier-phase signals transmitted by GPS and GLONASS satellites are monitored globally by Fugro’s worldwide network of reference stations. These observations are processed centrally in real-time using the company’s proprietary algorithms to generate precise corrections which are used to augment the standard signals broadcast by GPS and GLONASS satellites. Customers receive corrections via seven high-powered communications satellites, providing at least two independent G2+ data sources. According to Fugro, the new satellite positioning service will be particularly beneficial when seeking to measure latitude, longitude, elevation and speed with high accuracy in real-time.
