Abstract
A method solving for unknown location values and clock rate values of one or more nodes of a network of nodes communicating with one another entails associating multiple transmitting nodes and receiving nodes that produce, respectively, ping transmit events and ping receive events by receiving and associating receive count stamps to the ping transmit events. Ping event values corresponding to ping events relating to associated ones of the ping transmit events and the ping receive events are generated and accumulated. Solutions for transmit and receive node clock rate values and node location values relating to the transmit and receive ping events at arbitrary times within a harmonic block time interval are generated from the grouped, accumulated ping event values. The generated solutions for one of the associated multiple nodes are a function of the ping transmit events and ping receive events produced by the others of the associated multiple nodes.
