Maritime Navigation

Fishermen on a small wooden boat at sea using a handheld GPS navigation device — Boats navigating near mountainous coastlines rely on satellite GNSS systems to chart safe and precise courses at sea.

Satellite GNSS Guiding Ships Safely at Sea

1
GNSS Constellation
GPS/Galileo satellites broadcast precise timing signals
2
Signal Downlink
Vessel antenna receives signals from four-plus satellites
3
Position Fix
Onboard receiver triangulates location to sub-metre accuracy
4
Bridge & Crew
Chart plotter displays real-time route and hazard alerts

GNSS satellites transmit timing signals that ship receivers triangulate into precise positions, guiding mariners safely through any conditions.

Applications

2.3.1 Vessel Navigation Systems — Providing continuous, sovereign-grade positioning and timing signals to commercial and military vessels operating in national waters and beyond.
2.3.2 Arctic Route Navigation — Providing real-time positioning, sea-ice extent mapping and route guidance for vessels transiting the Northern Sea Route, Northwest Passage and Transpolar Sea Route.
2.3.3 Smart Shipping Routes — Using satellite-derived weather, ocean current, sea-state and traffic data to compute fuel-optimal, safe routing for commercial and naval vessels in real time.
2.3.4 Autonomous Vessel Navigation — Providing the precise, continuous, authenticated positioning and situational-awareness data feed that autonomous and remotely-operated vessels require to navigate safely without a crew aboard.
2.3.5 Maritime Rescue Beacons — Detecting, locating and relaying distress signals from EPIRB and PLB beacons via a sovereign satellite constellation to national search-and-rescue authorities.
2.3.6 Port Navigation Systems — Providing precise, sovereign-controlled positioning, timing and situational awareness to guide vessels safely through port approaches, berths and constrained waterways.
