Two bearers, one picture
Assets report over cellular where there is coverage and over satellite where there is not. Both streams land in one place.
Global network
One reach, from orbit to the quayside
Satellite and terrestrial cellular combine into a single reach — linking ports, shipping lanes and sites that sit far outside conventional coverage.
- Orbit
- Satellite constellations overhead
- Ground
- Downlinks to teleport stations
- Sea
- Ports and shipping lanes
- Land
- Remote and offshore sites
Drag to rotate
Vessels stay visible past the shoreline
Shore-based receivers stop at the horizon. Satellite tracking carries on, across the shipping lanes, for fleet oversight and port-area monitoring.
- Satellite vessel tracking and maritime intelligence
- Coverage beyond coastal receiver range
- Foundation for PORT PRIME port-area monitoring
