VERIPOS expands its proven inertial solution SPAN GNSS+INS technology from NovAtel, also part of Hexagon, to dynamic positioning applications and vessels.

SPAN technology delivers a deeply coupled GNSS and inertial navigation system (INS) that provides robust, reliable and continuous centimetre-level positioning for operators to maintain safety and maximise uptime. With a GNSS+INS solution, DP vessels can bridge outages in GNSS tracking and through short periods of radio frequency interference, jamming or spoofing.

VERIPOS provides offshore high precision positioning, delivering reliable and trustworthy GNSS solutions like the LD900 receiver, PPP correction services and positioning visualisation software. They demonstrate this expertise through SPAN technology’s deep coupling of GNSS and inertial measurements. Deep coupling describes how inertial measurements enhance the signal tracking for GNSS solutions, leading to improved resiliency against GNSS outages and enabling rapid reacquisition in case of interruptions. SPAN technology builds system robustness against potential signal outages, interference or disruptions while optimising operational efficiency.

“The robust positioning, heading, velocity and attitude measurements generated from a deeply coupled GNSS and inertial solution like SPAN technology is a game-changer to dynamic positioning operations,” said Dr. David Russell, Marine Segment Portfolio Manager at Hexagon’s Autonomy and Positioning division.

“SPAN technology has a proven track record of bridging outages, enabling rapid reacquisition of signals and building a reliable and robust positioning system. It’s the best option for vessels to ensure an added layer of resiliency and achieve continuous centimetre-level accuracy across all conditions," he added.

SPAN GNSS+INS technology is compatible with commercial inertial measurement units (IMUs) and scalable with your LD900 GNSS receiver, Quantum visualisation software and APEX correction services.
