Abstract
A GNSS receiver includes a sensing element for detecting an environmental condition, a control unit for dynamically calculating a sleep time duration in response to the environmental condition, and a digital processing unit that operates in a first mode or in a second mode based on the calculated sleep time duration and the environmental condition. The environmental condition may include a receiver signal strength indicator, a receiver velocity, the stability and precision of a local reference clock, a recent almanac, an ephemeris data, and the like. The first operation mode may include a tracking of satellite signals, and the second operation mode may include an acquisition operation, a tracking operation, or a combination of acquisition and tracking operations of satellite signals.
