Abstract: Methods and systems for femtocell positioning using low Earth orbit (LEO) satellite signals may comprise receiving an initial position of a wireless communication device (WCD) as entered by as user, service provider, or manufacturer, wherein the WCD comprises a LEO satellite signal receiver path (Rx). The WCD may be operable to provide wireless communication services to other WCDs. LEO signals may be received for determining a position of the WCD, which may be compared to a threshold radius defined by the initial position. The communication services may be enabled when the measured position is within the threshold radius. The WCD may comprise a femtocell device, a WiFi access point, or may provide cellular telephone service to the other WCDs. The position of the WCD may be measured upon powering up of the WCD, on a periodic basis, and/or when one or more motion sensors in the WCD detect motion.

Abstract: Methods and systems for indoor global navigation satellite system detection utilizing low Earth orbit satellite signals may comprise receiving low Earth orbit (LEO) RF satellite signals utilizing a LEO satellite signal receiver path (LEO Rx) in a wireless communication device comprising the LEO satellite signal receiver path and a medium Earth orbit satellite signal receiver path (MEO Rx). A received signal strength indicator (RSSI) may be measured for the received LEO signals and an expected received MEO signal strength may be calculated. A power level of the MEO Rx may be configured based on the calculated MEO signal strength by powering down when the calculated expected MEO signal strength is below a threshold level for MEO positioning purposes and/or powered up when it increases above the threshold level. The RSSI may be measured at a plurality of points along the LEO Rx.

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 medium Earth orbit (MEO) satellite signals and/or LEO signals in a receiver of the communication device. A radio frequency (RF) path may be configured to down-convert either of the signals, and a position of the communication device may be calculated utilizing the down-converted signals. The signals 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 signals may be down-converted to an intermediate frequency or down-converted directly to baseband frequencies. The signals 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.
