Aspects of a method and system for Doppler estimation may include generating, in a GNSS receiver operating in a duty-cycle mode, a plurality of lag-m products that may be based on a plurality of correlation coefficients corresponding to one or more received signals, wherein the plurality of correlation coefficients may be generated during an active period of the duty-cycle mode of operation. A Doppler frequency may be estimated based on the plurality of lag-m products. The GNSS receiver may be compliant with one or more standards comprising GALILEO, GLONASS, IRNSS, and BEIDOU. The active period of the duty-cycle mode may be chosen arbitrarily from a range of 1% to 99%.
