摘要： A method of scheduling wakeup events, method of operating a mobile transceiver, and devices configured for same are provided. In one aspect, there is provided a method of scheduling wakeup events for a mobile transceiver, comprising: obtaining a first GNSS data set comprising a plurality of GNSS coordinates, the first GNSS data set defining a route; applying a curve simplification algorithm to generate a second GNSS data set comprising a plurality of GNSS coordinates, wherein the second GNSS data set is a subset of the first GNSS data set; defining one or more alarms as wakeup events to activate the satellite receiver from a low power mode based on the plurality of GNSS coordinates of the second GNSS data, wherein the one or more wakeup events are each defined by an alarm; and applying the one or more alarms.
