摘要： A device is disclosed that is capable of determining its location using high-power with high accuracy, and using low-power with lower accuracy. By coordinating usage between the high power method and the low power, overall power consumption of the device can be significantly reduced without a significant reduction in accuracy. Such high accuracy may be achieved through the use of a GNSS unit, such a GPS receiver. In addition, the low-power alternative may be achieved using an accelerometer, together with software, hardware or firmware for extrapolating a speed based on the force measurements by the accelerometer. In this manner, the GPS receiver can be operated for only a fraction of overall use, primarily to provide adjustment data necessary to calibrate usage of the accelerometer.

摘要： An apparatus and method is provided for indoor/outdoor transition detection of devices to improve selection of the navigation algorithms. To determine whether an outdoor-to-indoor transition has occurred, a mobile device can determine whether a difference between an indoor position determined using indoor position information and outdoor position determined using outdoor position information is less than a threshold and can conclude that the mobile device transitioned from outdoor to indoor of the structure, if the difference is less than the threshold. Also, to determine whether an indoor-to-outdoor transition has occurred, the mobile device can determine whether an indoor position survey area exists, determine whether an outdoor position determined based on outdoor position information is outside of the survey area, and determine whether a signal strength associated with the outdoor position location information is greater than a threshold.
