Abstract
A satellite packet communications system comprises a number of ground-based sectors serviced via satellite communications nodes in polar orbits. Each sector is provided with an address incorporating a binary Gray code. Routing of a packet arriving at a satellite node and addressed to a particular sector is determined from the Grey code in the packet header. A comparison is performed between the packet address and an address stored in the node, the number and bit position of the difference between the nodes being used to determine the direction in which that packet should be routed.
