Over the next decade,Very High-Throughput Satellite(VHTS) will bring enough capacity to serve high speed internet and in-flight connectivity markets at scale, offering fiber-like services both in terms of price and speed. In this context, a generic VHTS mission utilizing Q/V-band feeder links and Ka-band user links is described. However, the rain attenuation on the feeder links becomes a limiting issue because of the higher frequencies. Toward this, an exploitation of multiple gateways(GWs) as a transmit diversity measure for overcoming severe propagation effects are being considered. Ground Application System(GAS) design of VHTS is illustrated including N+P GWs(N active and P redundant GWs) diversity, frequency plan, link budget and system capacity.
