Ground Control has been selected as one of three qualified vendors for Den Norske Krigsforsikring’s (DNK) new Tracking Programme, aimed at helping commercial vessels maintain trusted positioning when GNSS signals are disrupted. Its RockFLEET Assured platform uses Iridium satellite positioning and timing alongside satellite messaging and fleet tracking to support vessel operators in high-risk waters.
Ground Control has been selected by Den Norske Krigsforsikring (DNK) as one of three qualified vendors for its new Maritime Tracking Programme, giving shipowners and managers another option for maintaining independent vessel tracking when conventional GNSS signals are affected by jamming or spoofing.
The programme replaces DNK’s previous Raptor scheme with a multi-vendor model, allowing member organisations to select tracking technology suited to their operational requirements. Ground Control’s RockFLEET Assured is designed as a compact marine-grade tracker using Iridium satellite positioning and timing technology, known as Iridium STL.
The system provides independent position reporting when conventional GNSS cannot be trusted. It also includes bridge integrity alerts, two-way satellite messaging and fleet visibility through Ground Control’s Cloudloop tracking platform.
The appeal is its relatively simple integration into existing bridge systems. RockFLEET Assured uses standard NMEA protocols, allowing vessels to incorporate the tracker without requiring a separate approach to bridge data.
Alastair MacLeod, Chief Executive of Ground Control, said: “GNSS spoofing and jamming have become persistent operational realities, particularly across contested maritime zones this year. Commercial shipping now faces active, escalating threats to position reliability in high risk waters.”
He added: “Our partnership with DNK enables vessel operators to maintain trusted positioning and situational awareness where conventional GNSS cannot be relied upon. We are pleased to support DNK members in strengthening the resilience of their position, navigation and timing infrastructure.”
RockFLEET Assured is already operating on commercial vessels in high-risk waters and is integrated with DNK’s War Risk Insurance framework. This gives shipowners and managers a technology option that has already been deployed in the operating environment the programme is designed to address.
The wider issue for fleet management is the ability to maintain reliable navigation data when satellite navigation signals are deliberately disrupted. Independent tracking therefore sits alongside the wider digital infrastructure that ship operators are having to secure as vessel connectivity becomes more complex.
