3. Serve as a primary or backup link alongside VSAT systems

4. Support IoT, telemetry, and remote monitoring applications

5. Operate maintenance-free for up to 10 years

6. Simplify installation with a single-cable setup

—　Who is it for?　—

1. Commercial vessels (cargo ships, tankers, ferries)

2. Offshore fishing vessels and long-range operations

3. Government and military patrol boats

4. Yachts, expedition ships, and research vessels

5. Operators who require always-on, global connectivity

—　Key Features　—

1. Compact, Robust & Always On

With a 380 mm diameter antenna and a weight of just 7 kg, the SAILOR 4300 is a high‑performance, space‑efficient terminal that ensures reliability across the harshest seas — without compromising form or function.

2. Seamless Single‑Cable Installation

The integrated design supports a single‑cable ADU-to-BDU setup (up to 75 m coax), drastically simplifying deployment. No moving parts means fewer points of failure.

3. True Global L‑band Link via Iridium Certus

Tapping into the Iridium NEXT constellation, the SAILOR 4300 offers pole‑to‑pole coverage and supports data rates up to 704 kbps downlink / 176 kbps uplink (firmware upgradeable) for demanding digital applications.

4. Voice, Data & IoT in One System

In addition to data transmission, the SAILOR 4300 supports three simultaneous voice channels, features a built-in SIP server, four LAN ports, I/O interfaces, and an API, enabling integration with telemetry and fleet management systems.

5. A Decade of Maintenance-free Operation

Built to endure the rigors of maritime life, it's engineered to operate for 10 years without scheduled service — significantly reducing life‑cycle costs and downtime risk.

6. Flexible Deployment Options

Available in both bulkhead-mount and 19-inch rack-mount versions, it can be deployed as a primary terminal or a highly reliable backup link within a hybrid VSAT network architecture.

—　The Backbone of Next-Gen Vessel Connectivity　—

The SAILOR 4300 is more than a satellite terminal — it’s the backbone of next‑generation vessel connectivity. Its compact 38 cm antenna delivers high throughput via the Iridium Certus network, supporting speeds of up to 704 kbps downlink and 176 kbps uplink — even in polar or mid-ocean regions.

Installation is effortless: a single coaxial cable links the ADU and BDU, reducing structural work and minimizing cable runs. With no moving parts, the risk of mechanical wear is eliminated, ensuring reliable performance year after year.

In terms of functional integration, the SAILOR 4300 features three voice channels, built‑in SIP server, multiple LAN ports, and I/O  interfaces, enabling integration of crew communications, IoT sensors, telemetry data, and fleet systems — all through a single node.

Whether used as a primary communication system or as a VSAT backup solution, the SAILOR 4300—backed by its rugged design, low maintenance demands, and Cobham’s global service network—is an ideal choice for operators who prioritize always-on connectivity and seamless coverage.
