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 down-converted to determine a position of the wireless device. The signals may be down-converted utilizing local oscillator signals from a phase locked loop (PLL). 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.
