WavSat Satellite Constellation

The WavSat Satellite Constellation consists of two Low-Earth Orbiting (or "LEO" satellites): WavSat-2 and WavSat-1. In near-polar orbits and only hundreds of kilometers above the Earth's surface, each completes a revolution in just 90 minutes; at mid latitudes, there are typically 6 visible passes/day, each lasting about 10 minutes. Communication is full duplex, in the VHF (uplink at 149 MHz) and UHF (downlink at 400 MHz) bands, at 9600 bps. The system operates in a store-and-forward mode, that we refer to as real-enough time. The link-layer protocol for data uplink is AX.25, a connected-mode channel that is guaranteed error free. FCC licenses are provided through a unique operational agreement between Wavix and Volunteers in Technical Assistance.
