A method of calculating two position fixes, using satellite positioning. The method comprises: using an RF front-end (), receiving satellite positioning signals; using an analogue-to-digital converter (), sampling the received signals to generate signal samples; using a processor (), processing a first set of the samples as they are generated, to calculate a first position fix; storing information associated with the calculation in a memory (); storing a second set of the samples, or ranging measurements derived from the second set of samples, in the memory () for later processing to calculate a second position fix; and later, processing the second set of samples to calculate the second position fix, wherein the calculation of the second position fix is assisted by the information associated with the calculation of the first position fix. Also disclosed are other related methods and apparatus.

Hybrid satellite positioning with prediction

A method is disclosed to determine the topology of a network comprising a master node and one or more slave nodes interconnected using unidirectional data connections. The master node makes available data to succeeding nodes, and a slave node reads data from a preceding node, the read data comprising information of a path from master node to the slave node. A further method is disclosed to configure the path by sending data from the slave node to all nodes on the path via bi-directional data connections between nodes.
