Cobham SATCOM's NexGen MSAT system Integrates Radio, Cellular + SATCOM Nets

[Satnews] Cobham SATCOM’s new EXPLORER MSAT-G3 will be shown on the Cobham booth at IWCE 2016 (booth #1055).

An innovative new solution, EXPLORER MSAT-G3 is an IP-based Push-To-Talk (PTT) radio communications system that uniquely supports Satellite/3G/LTE/LAN backhaul and Land Mobile Radio (LMR) integration to provide seamless voice communication in any situation.

EXPLORER MSAT-G3 enables critical interoperable communications among homeland security officials, law enforcement, emergency responders and public safety officials.

EXPLORER MSAT-G3 is the next generation MSAT solution using the power of the Ligado Networks (former LightSquared) SkyTerra-1 satellite and ViaSat’s low-latency, IP-based L-band Mobile Satellite Services network. In the field, the system enables critical interoperable communications among homeland security officials, law enforcement, emergency responders, and public safety officials from various departments and agencies across the USA. EXPLORER MSAT-G3 extends coverage by combining satellite links and the existing cellular based networks, which can reduce terrestrial infrastructure costs while introducing significantly improved communications availability in any environment, when on the move. It is designed to cost effectively expand and augment LMR systems and as such, is compatible with many different brands of LMR to support lower capital costs.

EXPLORER MSAT-G3 uniquely supports Satellite/3G/LTE/LAN backhaul and Land Mobile Radio (LMR) integration.

The previous generation MSAT Push-To-Talk and Telephony voice is a satellite-only service, but the EXPLORER MSAT-G3 offers a wealth of additional benefits by extending MSAT Push–To-Talk capabilities to hybrid data networks. With no user intervention required, the system automatically routes voice and data traffic via the most reliable network available. The solution is based on Cobham SATCOM’s advanced EXPLORER Push-To-Talk system and the all-new EXPLORER 122, a compact Comms-On-The-Move (COTM) satellite terminal developed to operate over the Ligado SkyTerra-1 satellite network.

EXPLORER MSAT-G3 looks and feels just like a standard LMR system, utilizing a simple Push-To-Talk Control Speaker Microphone. The system is also as easy to install as a standard LMR system. Uniquely, up to two USB cellular modems (optional) can be connected to the PTT terminal to enable two independent cellular network connections. In action, EXPLORER MSAT-G3’s sophisticated routing functionality automatically switches between the available networks, dynamically selecting the most suitable one based on quality and availability at any time. This all happens seamlessly without user intervention.

The combination of the new generation MSAT, using the SkyTerra-1 satellite and ViaSat’s Managed Network Services, and EXPLORER MSAT-G3 will be a step change in communication capabilities for US government and emergency services,” said Henrik Nørrelykke, Vice President, Land Business, Cobham SATCOM. “By automatically and seamlessly routing voice and data communication over the best available network the system extends coverage and provides a more reliable connection. It essentially delivers more value and better performance in order to make people on the ground safer and more effective in their work.”
