  • Patent number: 11480642
    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.
    Type: Grant

  • Patent number: 11073591
    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.
