## Abstract

A radio communication system for transmitting data to a ground station includes plural stochastically distributed orbiting satellites with plural antennas traversing a portion of the earth's surface divided into zones. The ground station has a unique address identifying itself and the zone where it is located. A local area network associated with the ground node includes at least one satellite that stores the identity of a satellite antenna paired with a ground station antenna to form a radio link for transmitting data onboard the satellite to the ground station. Other satellites in the local area network store the ground node address and the identity of an antenna paired with an antenna in another satellite that also has stored the ground node address. A wide area network includes at least one satellite, each of which stores the identity of an antenna paired with an antenna of another satellite that has stored the ground node zone to form at least one inter-satellite radio link. If a satellite with data onboard is not in a local area network associated with the destination ground node or a wide area network, the satellite transmits the data toward the ground node zone.

## Claims

### Claim 1

A radio communication system for transmitting data to a terrestrial node via a radio route having at least one system node comprising at least one of a plurality of stochastically distributed orbiting satellite nodes, each of a plurality of said satellite nodes including:
a plurality of antennas for receiving and transmitting radio signals in different directions;
route creation circuitry for receiving an initial routing messages transmitted from the terrestrial node including address information identifying the terrestrial node and for transmitting further routing messages including the address information; and
a memory for storing the address information and an identity of the antenna on which the initial routing message was received,
wherein the route creation circuitry determines a quality of the received initial routing message, said quality indicating the suitability of the satellite for incorporation in a radio link for transmitting the data to the terrestrial node, and transmits on a plurality of the antennas further routing messages including the address information and the quality of the initial routing message.
