ArcLight Mobile Satellite Communication System

The conundrum that most see in mobile satellite communication systems is between sufficient power in the satellite signal and keeping system cost, size, and weight to levels that make it practical. You need a small antenna, but how do you hit a moving target without lots of RF power and avoid interfering with adjacent satellites?

ArcLight® Technology Makes The Difference

Through development of an intelligent, spread spectrum modem technology, called the ArcLight system, the problem is overcome by enabling the system to use a low-cost, small (11.5 cm) antenna. By using a technique similar to cellular CDMA, the system spreads the energy of the signal across a wide sprectrum and codes each bit for signal reassembly at the other end. The technology overcomes mobile communication challenges:

Co-exists with other services using the same frequency bands
Maintains sufficient capacity and great user experience for large numbers of network members (unlike ground based or cellular)
Eliminates blocked signals caused by line-of-sight (even helicopter blade) obstructions.

And our patented PCMA (Paired Carrier Multiple Access) enables essentially free return links by overlapping them onto the same bandwidth as the high-speed broadcast signal going to the plane, vessel or vehicle. Imagine the savings.

The Only Mobile Broadband System Approved for Operation on FSS Satellites

The architecture and waveform are specifically designed to meet strict FCC & ITU regulations. These automated network management features assure compliance:

Uplink power control
Congestion control
Automated login and network management
Adjacent satellite interference management
Auto-shutdown in restricted areas

For travelers in the proverbial “planes, trains, and automobiles” the super-efficient ArcLight technology is delivering fast, low-cost Internet Protocol (IP) communications at broadband access speeds equivalent to what you would expect at home or in the office.

And the performance is the same for the DoD, Homeland Defense, and Coalition forces, when they connect with the ViaSat Comms-on-the-move (C2OTM) system.
