The Explorer MSAT-G3 

Low Cost Satellite Two-Way Radio Solution

Explorer MSAT G3 Satellite Push to Talk RadioA cutting edge new push-to-talk (PTT) solution, The Explorer MSAT-G3 is an IP-based radio communications system that distinctly supports Satellite/3G/LTE/LAN with least-cost routing and Land Mobile Radio integration to provide reliable voice and data communication in any environment.  The Explorer MSAT-G3  will allow for a broad range of new terminal-based data-rich applications secured by AES-256 encryption connected to a ruggedized mobile PTT interface.  This new terminal provides seamless handover of voice calls and also supports Bluetooth and WiFi data connectivity.

The Explorer MSAT-G3 Satellite Two-Way Radio platform is designed to provide reliable, low cost satellite Dispatch, voice and data connectivity to Utilities, Transportation, Homeland Security officials, Law Enforcement, Emergency Responders and Public Safety name only a few.

The previous generation MSAT G2 is a satellite-only voice and slow data service, but the Explorer MSAT-G3 offers additional benefits by extending 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 G3 looks and feels just like a standard LMR system, utilizing a simple Push-To-Talk Microphone with speaker. The system is also as easy to install as a standard LMR system. Uniquely, up to two USB cellular modems can be connected to the PTT terminal to enable two independent cellular network connections.

The 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.
