Ultra low power global navigation satellite system (GNSS) receiver operation

Apparatuses, methods, and other embodiments associated with low power GNSS receiver operation are described. According to one embodiment, an apparatus includes a pre-processor configured to generate digitized signals from satellite signals according to a set of pre-processing functions. The satellite signals are navigation satellite signals. The pre-processor is configured to store the digitized signals in a memory. The apparatus includes a processor configured to produce a navigation result from the digitized signals stored in the memory. The apparatus includes a control logic configured to independently power the digital pre-processor and the processing logic by powering either the digital or the processor at a time.
