Do you trust the reliability of current maritime navigation systems against modern electronic interference?
Cornes Technologies has unveiled the Guide One, a standalone navigation aid that utilizes low earth orbit (LEO) satellite positioning. This system serves as a backup to conventional global navigation satellite systems (GNSS) when signals are compromised by jamming or spoofing.
Why it matters
Rising instances of signal interference in maritime trading corridors like the Red Sea and Persian Gulf have created a critical need for redundant positioning technologies. This development provides a path for vessels to maintain navigation safety without requiring expensive modifications to bridge equipment.
The Guide One system utilizes LEO signals that are approximately 1,000 times stronger than conventional GNSS signals. This high signal strength enables accurate positioning within 100 metres even when traditional navigation frequencies are actively jammed.
The players
Cornes Technologies
A Japanese maritime technology firm specializing in navigation systems and vessel instrumentation.
The details
The device operates as a standalone unit, independent of existing electronic chart display and information systems (ECDIS — hardware used for displaying navigational charts). It continuously monitors GNSS status, and if it detects interference, the unit automatically switches to LEO-derived positioning. The hardware installation requires only the unit itself and an antenna, avoiding the need for complex integration with other bridge navigation systems.
Timeline
September 2026: The Guide One chartplotter was unveiled.
January 2027: Commercial orders will open for the system.
The Tech Race
As high-risk trading regions like the Black Sea experience more frequent navigation outages, the race to build reliable, jam-resistant hardware has intensified. The Guide One marks a shift toward dedicated LEO-based backups that operate outside of the vulnerable traditional GNSS ecosystem.
Maritime operators and fleet managers can expect to procure the system beginning in early 2027 to mitigate risks in high-interference zones. The hardware is designed for straightforward installation, allowing vessels to upgrade their safety protocols without major bridge overhauls.
The takeaway
The Guide One offers a specialized solution to the growing threat of maritime electronic warfare by leveraging the higher signal density of LEO networks. Watch for the official commercial launch in January 2027 to see how adoption scales across global merchant fleets.
What happens next
Commercial orders for the Guide One system are scheduled to open in January 2027.
