Abstract
Systems, apparatus and methods in a mobile device to multiplex two global navigation satellite system (GNSS) signals on a single hardware receiver chain are presented. The GNSS signals may come from a common GNSS system on two bands of two different GNSS systems overlapping on a common band. A duty cycle of the GNSS signals may be based on a harmonic being within one of the first band and the second band. The duty cycle may be based on signal quality, such as indicating a jammed or non jammed signal. The duty cycle may be of unequal proportions and less than 100% such that the receiver chain is idle for a percentage of time.
