Abstract

A method for generating private eLoran signals includes receiving, by a transmitter site, a transmission key. The transmitter site is configured to transmit a timing signal at a fixed time. The method also includes determining, by the transmitter site, for the timing signal configured to be transmitted at the fixed time, a pseudo-random transmission time for transmitting the timing signal, and initiating transmission, by the transmitter site, of the timing signal at the pseudo-random transmission time.]. A method for receiving private timing signals includes determining, by the receiver device and using the fixed time, a pseudo-random time for receiving the timing signal from the transmitter site, receiving, by the receiver device, the timing signal at the pseudo-random time, and using, by the receiver device, the timing signal to determine at least one of a time, a longitude, and a latitude at the receiver device.
