Iridium World Wide
The Iridium system is a satellite-based, wireless personal communications network providing a robust suite of voice and data features all over the globe. MORE
BGAN High Speed Data
BGAN is accessible via a range of small, lightweight satellite terminals. They can be used both indoors and outdoors, being robust enough to withstand challenging environments and extremes of temperature. MORE
Inmarsat Satellite Network
Inmarsat has been at the leading edge of satellite communications for nearly 30 years providing voice and high-speed data services to almost anywhere on the planet - on land, at sea, and in the air. MORE
SATELLITE PHONE SYSTEMS
Communications satellites (SATCOM) are satellites stationed in space for the purposes of telecommunications. Satellite communications networks use satellites in either LEO or GEO orbits.
All satellite systems require "Line of Site" to the satellite and an antenna placement outside is absolutely necessary for correct operation and maximum performance. For indoor systems, an external type antenna is installed outside with direct viewing to the satellites or satellite.
Low Earth Orbit
For LEO (Low Earth Orbit) constellations such as Iridium or Globalstar, smaller Omni-Directional Antenna are used with Antenna mounting as high as possible with a maximum view of 360 degrees to the horizon for optimal signal strength and performance. It is possible to have some obstructions to the sky, but this will degregate overall system performance. The more blockage to the sky the lower overall quality of service. These Antennas are extremely suitable for boats of all sizes with excellent performance in high seas.
For (GEO) Geosynchronous Satellite Constellations such as Inmarsat BGAN and VSAT systems, a directional antenna pointed directly to the satellite is necessary. This "Look Angle" is critical and must have no obstructions for maximum signal strength and performance.
