Methods and apparatus are provided for power saving in GNSS receivers. In one novel aspect, the ME tracking period, the ME interval, and the PE working period, the PE interval are dynamically determined based on the GNSS signal conditions and/or the user requirements. In one embodiment, acceptable provision estimated position fix are used. Estimated position result is generated at each GPS position interval if there is no position result generated by the PE working period. In another embodiment, the ME-tracking and/or the PE-working are adjusted to minimum operation needs by using ME-partial (MEP) and/or PE-partial (PEP). PEP is arranged aligned with MEP. In yet another embodiment, the PE working period is delayed such that the PE working period is aligned with the ME tracking period. The position result is generated based on a last epoch's measurement obtained in the previous ME tracking period.
A method for controlling a power saving operation, applied to an apparatus comprising a global navigation satellite system (GNSS) receiver, a monitoring engine (ME) module and a positioning engine (PE) module, the method comprising:
An apparatus can perform a power saving operation, comprising:
