    Hexagon | Veripos expands SPAN GNSS+INS portfolio for dynamic positioning

    Ensures safe operations through reliable, robust and continuous positioning with GNSS+INS integration

    Hexagon | Veripos has expanded its inertial solution SPAN GNSS+INS technology from NovAtel, also part of Hexagon, to dynamic positioning (DP) applications and vessels.

    SPAN technology delivers a deeply coupled GNSS and inertial navigation system (INS) that provides robust, reliable and continuous centimeter-level positioning for operators to maintain safety and maximize 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 is a leader in offshore high-precision positioning, delivering reliable and trustworthy GNSS solutions such as the LD900 receiver, PPP correction services and positioning visualization software. This expertise is demonstrated 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 optimizing 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 David Russell, marine segment portfolio manager at Hexagon’s Autonomy & 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 centimeter-level accuracy across all conditions.”

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

    Veripos has released the LD900, a quad-band GNSS receiver capable of tracking GPS, GLONASS, BeiDou, Galileo and QZSS constellations to provide reliable and accurate positioning. Access to multiple GNSS signals allow for better satellite availability and reduce the impact of satellite masking or blockage, which can affect positioning.

    LD900 also receives L-band signals on multiple channels, providing access to the worldwide independent correction links and services provided by Veripos. With correction data available simultaneously from up to three correction satellites, the impact of satellite masking can be minimized to ensure reliable reception of correction data. Using the independent L-band RF input on the LD900 allows the connection of a dedicated L-band antenna ensuring optimal reception of correction services, especially at high latitudes, the company said.

    Veripos provides accurate and reliable positioning for all marine applications via their redundant positioning and multi-frequency precise point positioning (PPP) Apex and Ultra services.

    The Apex5 correction service utilizes all GNSS constellations delivering 5cm positioning accuracy for use in the most demanding offshore applications. Real-time kinematic (RTK) corrections can be utilized by the LD900 for applications where this service is required.

    The intuitive color display and navigation menu makes setup, configuration and system status monitoring simple. The display also helps troubleshoot issues with the LD900 allowing faults to be quickly diagnosed and resolved. The LD900 can also be configured remotely through the Veripos Quantum software.
