Description
Bottom Line Up Front (BLUF): Operational Overview
The Cobham Sailor EXPLORER EX325 BGAN Vehicular Satellite Terminal with PTT (Push-to-Talk) is a type-approved commercial marine land-mobile system engineered for high-reliability deep-sea and offshore vessel operations. Compliant with international IMO/SOLAS and IEC standards, the unit is fully supplied, bench-tested, and supported worldwide by Seanav Marine from our Dubai Maritime City (DMC) technical facility.
Cobham EXPLORER EX325 BGAN PTT (Push to Talk) is an IP-based radio communications device that supports BGAN Satellite/3G/LTE/LAN backhaul and land mobile radio (LMR) integration to provide seamless voice communication in any situation. It is a cost effective system designed to expand and augment traditional LMR systems widely in the Public Safety, Utility, Mining, and Oil & Gas sectors.
Explorer PTT extends legacy push to talk capabilities to hybrid data networks such as terrestrial cellular networks (where available), supplemented by the Inmarsat BGAN satellite network where no terrestrial network coverage is present. With no user intervention required, the system automatically routes voice and data traffic via the least expensive and most reliable network available.
Explorer PTT turns traditional LMR, satellite cellular and the internet into a closed managed Wide Area Network, with beyond line-of-sight communications. The look and feel is exactly like a legacy LMR system utilizing a simple push to talk speaker microphone handset. Vehicle installation includes a BGAN on-the-move terminal and an Explorer PTT terminal with a control speaker microphone. Up to two USB modems (optional) can be connected to the PTT base station allowing for two independent cellular network connections. The all important least cost routing functionality enables automatic switching between the available networks.
Key Engineering Features & Operational Advantages
- Ruggedized and easy to use PTT
- Built-in support for LMR devices to ensure over-the-horizon radio communications
- Voice-over-IP technologies optimized for use under difficult satellite or terrestrial link conditions
- Beyond Line-of-Sight communication – global coverage
