SATRAD G3 Push-To-Talk

SATRAD-G3 looks and feels just like a standard LMR system, utilizing a simple PTT handset. In action, sophisticated routing functionality automatically switches between the available networks, dynamically selecting the most suitable one based on cost, quality and availability at any time. This all happens without user intervention, meaning they can get on and do their job, just like they have always done.

Overview

SATRAD Communication Evolved

The SATRAD G3 is an IP-based Push-To-Talk (PTT) radio communications system that supports Satellite/LTE/3G/LAN back-haul and Land Mobile Radio (LMR) integration to provide seamless voice communication in any situation. It is the next generation SATRAD solution utilizing the power of the Ligado Networks (former LightSquared) SkyTerra-1 satellite and ViaSat’s IP-based L-band Mobile Satellite Services network.

The collaboration between Network Innovations, Cobham, Ligado Networks and ViaSat brings to market the next- generation features that expand upon the legacy of SATRAD- G2 while retaining the platform’s popular flat-rate service plans.

The SATRAD G3 platform will allow for a broad range of new data-rich applications secured by AES-256 encryption connected to a ruggedized EXPLORER PTT terminal that supports Satellite/3G/LTE/LAN backhaul and Land Mobile Radio integration to provide seamless handover of voice calls.

Enhanced Capabilities

SATRAD-G3 looks and feels just like a standard LMR system, utilizing a simple PTT handset. It’s just as easy to install as a standard system too. Uniquely, up to two USB cellular modems (optional) can be connected to the PTT terminal allowing for two independent cellular network connections.

In action, sophisticated routing functionality automatically switches between the available networks, dynamically selecting the most suitable one based on cost, quality and availability at any time. This all happens without user intervention, meaning they can get on and do their job, just like they have always done.

The SATRAD-G3 solution solves many challenges faced by traditional LMR system operators:

  • Coverage area is extended by combining satellite links and the existing cellular based networks.
  • Least cost routing, automatic switching of PTT calls between satellite and cellular connectivity.
  • Terrestrial infrastructure costs are reduced, allowing for a higher return on investment.
  • Users benefit from constant communications availability when on the move.
  • Scalable from two to thousands of units.
  • Compatibility with many different brands of land mobile radios

SATRAD Interoperability

Network Innovations’ SATRAD solution includes Talk Group access where critical, interdependent communications can be shared privately and reliably. For national and regional homeland, emergency, and first responder agencies, SMART Talk Group access is available through Ligado.

The SATRAD-G3 solution meets the needs of:

  • Emergency first responders and law enforcement agencies during emergencies and in disaster recovery situations.
  • Mobile workers who require voice connectivity outside terrestrial network coverage for safety purposes and efficiency of operation.

The SATRAD-G3 solution will be able to interoperate with the legacy SATRAD G2 hardware. The new SATRAD G3 hardware will be able to work in the same user Talk Groups provided by Network Innovations as SATRAD-G2 terminals. This feature and the completed server infrastructure will be ready later in 2017.

Beyond Line-Of-Sight Push-To-Talk Communication

The SATRAD-G3 utilizes the power of the Ligado SkyTerra-1 satellite, combined with ViaSat’s Managed Network Services, and Cobham’s industry leading Push- To-Talk technologies.

EXPLORER hardware

The solution is based on the new EXPLORER 122 L-Band satellite terminal combined with the advanced EXPLORER PTT system from Cobham SATCOM.

  • A ruggedized and easy to use digital Push-To-Talk communication solution.
  • Designed to cost effectively expand and augment LMR systems.
  • Built-in support for LMR devices to ensure over-the-horizon radiocommunication.
  • Voice-over-IP technologies optimized for use under difficult satelliteor terrestrial link conditions.
  • Automatic PTT voice, least cost routing between cellular(LTE/3G/2G) and the SkyTerra-1 satellite network.

Integrated seamlessly, these proven Cobham technologies create an advanced, highly reliable, and easy-to-use hardware platform that enables emergency services in North America to communicate effectively.

SkyTerra-1 Satellite

Ligado Networks provides ubiquitous coverage throughout North America over one of the most powerful L-band commercial satellites ever built. The high-powered SkyTerra-1 satellite enables transmissions to small fixed and mobile devices by using an antenna with 22-meter reflector—the largest satellite reflector to be put into service on a commercial satellite, bringing higher data throughputs to smaller devices.
