Abstract: Methods and systems for a dual mode global navigation satellite system may comprise selectively enabling a medium Earth orbit (MEO) radio frequency (RF) path and a low Earth orbit (LEO) RF path in a wireless communication device to receive RF satellite signals. The signals may be processed to determine a position of the wireless device. The signals may be digitized and buffered before further processing. The RF paths may be time-division duplexed by the selective enabling of the MEO and LEO paths. Acquisition and tracking modules in the MEO RF path may be blanked when the LEO RF path is enabled. The MEO RF path may be powered down when the LEO RF path is enabled. The signals may be down-converted to an intermediate frequency before down-converting to baseband frequencies or may be down-converted directly to baseband frequencies. In-phase and quadrature signals may be processed.

Abstract: Methods and systems for power optimization of a global navigation satellite system may comprise receiving LEO RF satellite signals utilizing a LEO satellite signal receiver path (LEO Rx) in a wireless communication device (WCD). Circuitry in the LEO Rx may be configured in a powered down state based on a sleep schedule. A location of the wireless communication device may be determined utilizing LEO signals received by the LEO Rx. The sleep schedule may be based on a desired accuracy of the determined location, the relative strengths of signals received from a plurality of LEO satellites, a relevance factor generated by a position engine and communicated to the sort module, or a desired power level of the WCD. The relative strengths of received signals may be compared utilizing a sort module in a LEO demodulator in the LEO satellite signal receiver path.

Abstract: Methods and systems for repurposing of a global navigation satellite system receiver for receiving low-earth orbit (LEO) communication satellite timing signals may comprise receiving a medium Earth orbit (MEO) satellite signal and/or a LEO signal in a receiver of the communication device. The MEO or LEO signal may be down-converted, and a position of the communication device may be calculated utilizing the down-converted signal. The signal may be down-converted utilizing a local oscillator signal generated by a phase locked loop (PLL), which may be delta-sigma modulated via a fractional-N divider. A clock signal may be communicated to the PLL utilizing a temperature-compensated crystal oscillator. The signal may be down-converted to an intermediate frequency or down-converted directly to baseband frequencies. The signal may be processed utilizing surface acoustic wave (SAW) filters. In-phase and quadrature signals may be processed in the RF path utilizing a two-stage polyphase filter.
