Abstract: Performing a combination localization technique includes determining a target localization parameter, selecting a combination localization technique in accordance with the target localization parameter, including a first localization technique associated with a first power error time profile, and a second localization technique associated with a second power error time profile. A device location is determined using the first localization technique for a first time period in accordance with the first power error time profile, and an updated device location is determined using the second localization technique in response to a triggering condition. A further updated device location is determined using the first localization technique following the first time period based on the updated device location. At least one of a combined energy value and a combined maximum error rate for the combination localization technique satisfies the target localization parameter.
