A satellite communications system comprising satellites in low earth orbit (LEO) as well as one or more satellites in orbits other than LEO, such as satellites in medium earth orbit (MEO) and/or satellites in geostationary orbit (GEO). The system routes data packets, such as may be received from the Internet, to either the LEO satellites or non-LEO satellites in accordance with routing logic. In some embodiments, the routing logic is based on the latency of the communications.
