This publication describes techniques for accurately determining a current location of a computing device over time while reducing power consumption. The computing device may include a Pretrim Manager configured to direct a processor of the device to perform a sequence of techniques to update the current location of the device over time using a combination of techniques, each technique varying in accuracy and power consumption. For example, the combination of techniques may include a true-range multilateration, a dead reckoning, an atmospheric-pressure adjustment, and a true-range inertial multilateration. Each technique is repeated at a unique frequency to minimize power consumed by the device while accurately determining the current location of the device to enhance a user experience.
