Cobham Sailor Fleet One Inmarsat FleetBroadband

Additional information


With its compact, lightweight antenna and simple installation, SAILOR Fleet One is a low-cost entry point to the world of maritime satcom that keeps you connected at all times. It enables reliable voice calling and Internet connectivity on Inmarsat’s Fleet One service, which harnesses the power of the established Inmarsat-4 satellite constellation for global coverage.

Data & voice – SAILOR Fleet One enables data connectivity up to 100kbps and voice calling on a single line. Its capabilities offer significant communications functionality for recreational and fishing users who need reliable voice communications and Internet connectivity on board, when cellular networks aren’t available, or just don’t offer the quality needed for good communication.

First choice for Fleet One – Built by the people behind the leading SAILOR FleetBroadband range, SAILOR Fleet One is the first choice for boat owners choosing the Fleet One service because it ensures reliable connectivity even on smaller boats that don’t have the room, or the budget, for larger satcoms
