Project to Enable Autonomous Navigation in Denied Environments

A new project involving leading ship technology companies aims to help unmanned autonomous vessels navigate, even when they lose access to global navigation satellite systems (GNSS).  The project will combine underwater positioning systems from Sonardyne International Ltd. and Guidance Marine Limited’s relative surface positioning systems into one integrated solution to enable vessels to maintain safe passage in GNSS-denied environments or for dynamic positioning systems to maintain their position if they lose GNSS access or other sensors fail.The AutoMINDER (Autonomous MarIne Navigation in

There is a need for an integrated approach to positioning using all available means.” In addition to the insights provided by the exhibition and main conference schedule

Kongsberg Position Refrence System Integrates GNSS Services

Kongsberg Maritime has expanded its established satellite position reference system portfolio with the introduction of a new system that integrates all available Global Navigation Satellite Systems (GNSS) and all possible correction services. The new DPS 432 combines full decimetre accuracy with high integrity and availability of GNSS data, supporting the safety and efficiency of offshore operations that rely on advanced Dynamic Positioning (DP) systems. DPS 432 integrates signals from GPS, GLONASS, BeiDou and Galileo, and regional correction signals including SBAS (e.g. WAAS, EGNOS, MSAS, GAGAN)

Fugro Awarded a Three-Year Positioning Contract by PGS

seismic and electromagnetic services, data acquisition, imaging, reservoir services and multi-client library data.   Fugro, a provider of precise satellite positioning to the offshore oil and gas industry, will supply PGS vessels with a number of completely independent Global Navigation Satellite Systems (GNSS). These systems include Fugro’s recently launched Starfix.G4 - the first commercial GNSS service to utilise all available GNSS systems (GPS, GLONASS, Galileo and BeiDou), giving sub-decimetre accuracy - and Starfix.G2+, a global service offering centimeter accuracy in both

Fugro Launches G4 Service

  Fugro has further extended its technology leadership in the field of GNSS augmentation systems for offshore positioning applications with the launch of its G4 service. The new satellite correction service is the first to take advantage of all four GNSS (Global Navigation Satellite Systems): GPS, GLONASS, BeiDou and Galileo. GNSS augmentation services significantly improve position accuracy compared to unaided GNSS receivers, which are commonly used in the consumer sector.   By using all available GNSS satellites, Fugro’s G4 service is designed to improve availability and reliability
