Jotron Acquires AD Navigation – Becoming a global leader in Portable Pilot Units (PPU) and precision navigation

Jotron announced the acquisition of AD Navigation, a move that secures the company a market-leading position in Portable Pilot Units (PPU). By integrating AD Navigation’s expertise, Jotron expands its global portfolio with the world’s most accurate portable navigation systems, adding critical, battle-tested technology to counter the growing threat of GNSS (Global Navigation Satellite System) spoofing and jamming.

Validated by real-world jamming tests

AD Navigation is renowned for producing high-precision portable navigation systems that allow seapilots to assist incoming ships to dock safely. While standard ship GNSS  receivers often fail during jamming-attacks, AD Navigation’s unique technology has proven its resilience through rigorous live testing.

AD Navigation’s XR2 Portable Pilot Unit system allows maritime pilots to bring a “layer of truth” on board, ensuring safe docking even when satellite signals are compromised. This technology will also create powerful, future synergies with Jotron’s existing communication and navigation portfolio. AD Navigation’s proven expertise in countering spoofing and jamming reinforces Jotron’s long-standing commitment to maritime safety.

For Jotron, this acquisition is about delivering a complete safety package. By becoming part of Jotron, this technology will now reach a global market through Jotron’s established network.

Continuity and innovation

All employees in AD Navigation will continue in the company, ensuring that the specialized competence remains intact.

Innovation is at the core of Jotron’s DNA, creating a strong cultural fit between the two companies. The specialists from AD Navigation will complement Jotron’s already strong development environment, allowing both teams to challenge and strengthen each other.

With AD Navigation’s anti-spoofing and anti-jamming technology, combined with Jotron’s proven communication and navigation systems, we are adding yet another vital dimension to its “Safe Journey” mission. This acquisition positions Jotron at the forefront of integrated communication and navigation solutions for maritime safety worldwide.
