Abstract: A method, system and computer program product for conserving power in a GPS-based navigation system. The navigation system receives input from the driver selecting a portion(s) of the route (route from the current location of the vehicle to the destination) where the driver requests guidance. For those portions of the route not selected by the driver to receive guidance, the navigation system implements a low detail mode of operation. In such a mode of operation, the navigation system reduces its update frequency as well as displays less detailed graphics so as to consume less power. For those portions selected by the driver to receive guidance, the navigation system implements a high detail mode of operation, where the navigation system is capable of audio-visually communicating to the driver instructions for reaching a given destination. In this manner, the power consumed by the navigation system will be more efficiently utilized.

Abstract: An approach is provided for energy-efficient location tracking. An energy saving module obtains measured location data of the user equipment, and determines a function to forecast locations of the user equipment based on the measured location data to output forecast location data. The energy saving module further receives movement data from a sensor of the user equipment, and converts the movement data to converted location data. The energy saving module then compares the forecast location data with the converted location data for a deviation, and then it either initiates reporting of the deviation when the deviation exceeds a predetermined range, or disables the reporting of the deviation when the deviation is within the predetermined range.

Abstract: Provided is a critical point method used to determine the points of a real-time stream of location data, such as Global Positioning System (GPS) data, that should be retained based on their importance in reconstructing the travel path of a mobile device. The method may run on a mobile device or on a server. When run on a mobile device, the method reduces the amount of data transferred between mediums by only transferring points that are critical to reconstructing the path of travel of the mobile device. This reduction saves power used in the wireless transmission and reception of the non-critical data and the bandwidth used while transmitting non-critical data. The method may be run every time a new position is calculated. When a new position is determined to be a critical point, the point is transmitted. If the new position is not a critical point, then the point is discarded.
