Abstract
Methods and systems for an embedded and hosted architecture for a medium Earth orbit satellite and low Earth orbit satellite positioning engine may comprise receiving LEO RF satellite signals and MEO satellite signals in a wireless communication device (WCD) comprising a low Earth orbit (LEO) satellite signal receiver path, a medium Earth orbit (MEO) satellite signal receiver path, and a dual-mode position engine comprising a coarse location module and a fine location module. The received LEO and MEO signals may be demodulated and coarse and fine positions may be determined from the demodulated signals utilizing the dual-mode position engine. A configuration input may be communicated to the position engine, wherein the configuration input comprises an initial position estimate for the WCD. The coarse position may be determined utilizing demodulated LEO signals and/or demodulated MEO signals. The fine position may be determined utilizing demodulated LEO signals and/or demodulated MEO signals.
