Abstract
A multi-function appliance for use in a satellite navigation data distribution system is described. A computer includes an input/output interface and a memory the computer is configured with a plurality of modules. The plurality of modules includes a satellite signal receiver, a packetizer, a network interface, a concentrator, and a decoder. The satellite signal receiver is configured to obtain satellite navigation data from satellite signals. The packetizer is configured to packetize satellite navigation data to produce a reference packet stream. The network interface is configured to transmit packet streams towards a network. The concentrator is configured to remove duplicate packets within reference packet streams to generate a combined packet stream. The decoder is configured to decode satellite data from packet streams. In this manner, the computer may be configured to perform a reference station function, a hub function, or a server function in the satellite navigation data distribution network.
