Abstract: A method is disclosed. In various examples, the method may include receiving an instruction for generating a signal comprising a ranging signal and a data signal. The method may also include transmitting, via a terrestrial transmitter for transmitting radio waves having encoded messaging information and timing information for one or more of positioning, navigation and timing, the signal at least partially responsive to the instruction. The signal may include a pulse group comprising a number of ranging pulses and a number of data pulses subsequent to the number of ranging pulses. Respective ones of the number of data pulses may have a phase of either a positive-going phase or a negative-going phase. Information may be encoded using the either positive-going phases or negative-going phases of the data pulses.

Abstract: A method is disclosed. In various examples, the method may include receiving an instruction for generating a ranging signal, and transmitting the ranging signal at least partially responsive to the instruction. In various examples the ranging signal may be transmitted via a terrestrial transmitter for transmitting radio waves having encoded messaging information and timing information for one or more of positioning, navigation and timing. In various examples, the ranging signal may exhibit a first ranging pulse and a second ranging pulse of a pulse group and an encoded transmitter identifier, the transmitter identifier encoded by modulating an inter-pulse interval defined between a start of the first ranging pulse and a start of the second ranging pulse.

Abstract: A device is disclosed. In one or more examples, the device may include an antenna to receive a signal comprising a ranging signal and a data signal. The signal may encode timing information for one or more of positioning, navigation, and timing. The signal may include a first pulse having a first start time and a second pulse having a second start time. The second start time may be an integer number of inter-pulse intervals plus an encoding delay after the first start time. The encoding delay may encode data. The device may include a processor to obtain the data responsive to the encoding delay.
