1. A radio communications system capable of providing a radio route for transmitting data between plural system nodes including multiple orbiting satellite nodes, wherein:
at least one of said multiple orbiting satellite nodes comprises a rotating satellite node that during each orbit rotates continuously through plural revolutions about a rotational axis passing through said orbiting satellite node;
each of a number of said orbiting satellite nodes includes a plurality of satellite antennas having separate identities for transmitting and receiving radio signals in a plurality of different directions associated with corresponding antenna identities, route creation circuitry for transmitting routing messages to and receiving routing messages transmitted from other system nodes, and data transmission circuitry for transmitting data to other system nodes;
said route creation circuitry of a said rotating satellite node determines a value of a parameter associated with a routing message received by said rotating satellite node from another system node and the corresponding identity of the satellite antenna that received said routing message, the value of the parameter indicating the suitability of including said rotating satellite node as a link in a radio route for transmitting the data to the other system node; and
said data transmission circuitry of the said rotating satellite node transmits the data to the other system node using a satellite antenna the identity of which is selected by said route creation circuitry of the said rotating satellite node based at least in part on the value of the parameter associated with a routing message received on said satellite antenna.
