A method to be performed at a mobile device, the method comprising:

• determining a plurality of configuration hypotheses comprising different combinations of one of a plurality of different Space Vehicle (SV) sets and one of a plurality of different duty cycle profiles;
• selecting from the plurality of configuration hypotheses a selected measurement configuration comprising a selected SV set and a selected duty cycle profile, based at least on an estimated power consumption corresponding to the selected measurement configuration and an estimated position error corresponding to the selected measurement configuration, wherein the selected measurement configuration is according to a positioning performance budget criterion, the estimated position error corresponding to the selected measurement configuration is equal to or below a position error limit, and the estimated power consumption corresponding to the selected measurement configuration is a lowest of estimated power consumptions corresponding to configuration hypotheses having an estimated position error equal to or below the position error limit;
• and
• configuring a Global Navigation Satellite System (GNSS) measurement by a GNSS receiver of the mobile device using the selected SV set and according to the selected duty cycle.

A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one processor, enable the at least one processor to cause a mobile device to:

• determine a plurality of configuration hypotheses comprising different combinations of one of a plurality of different Space Vehicle (SV) sets and one of a plurality of different duty cycle profiles;
• receive a selection criterion indicator to indicate preference between a power budget criterion and a positioning performance budget criterion;
• select from the plurality of configuration hypotheses a selected measurement configuration comprising a selected SV set and a selected duty cycle profile, based at least on an estimated power consumption corresponding to the selected measurement configuration and an estimated position error corresponding to the selected measurement configuration, wherein the instructions, when executed, cause the mobile device to, based on the selection criterion indicator, determine the selected measurement configuration according to the power budget criterion or the positioning performance budget criterion;
• and
• configure a Global Navigation Satellite System (GNSS) measurement by a GNSS receiver of the mobile device using the selected SV set and according to the selected duty cycle.
