Satellite Network
The satellites making up the network are small in size, weighing less than one hundred pounds each. This is due to several key design elements all intended to keep costs lower than other networks thus enabling significantly lower subscription rates for final customers.
Once in place, the satellites require no propulsion system to maintain their operating orbit which also helps to extend their lifespan in comparison with geostationary satellites. Communication with both Subscriber Communicators and Gateway Earth Stations is conducted using the same VHF and UHF equipment thus reducing complexity, size, power and cost requirements of supporting multiple communications on a single satellite.
The use of the system uplink (Earth-to-space) spectrum is managed by an on-board computer that employs Dynamic Channel Activity Assignment System, or DCAAS. DCAAS continuously scans the authorized spectrum, identifies frequencies already in use and dynamically assigns your uplink channel to minimize interference. DCAAS changes the uplink frequency at least every 15 seconds, which allows our system to coexist with the current users of the VHF frequency band, and limits interference.
