Abstract
Embodiments of the invention provide systems and methods for tracking a mobile device using sensors within the device and without using external signals to determine location, velocity, or heading. According to one embodiment, locating and tracking a mobile device can comprise reading sensor data from each of a plurality of sensors within the mobile device. The sensors can provide the sensor data without relying on a signal from a device external to the mobile device. For example, the plurality of sensors can comprise a compass, a gyroscope, and an accelerometer. Motion, velocity, and heading of the mobile device can be determined based on the sensor data.
