Abstract
A method for generating private eLoran signals includes receiving, by a transmitter that is configured to transmit a transmission at a fixed time, a transmission key; determining, by the transmitter, a pseudo-random transmission time for transmitting the transmission, where the pseudo-random transmission time is determined using the transmission key; and initiating transmission, by the transmitter, of the transmission at the pseudo-random transmission time. A receiving device includes a processor that is configured to obtain a pseudo-random time for receiving a transmission from a transmitter; receive the transmission at the pseudo-random time; and use the transmission to determine at least one of a time, a longitude, or a latitude at the receiving device.
