Abstract
A method and apparatus for detecting bad signals at a global positioning system (GPS) enabled device are described. In one embodiment, the GPS enabled device includes one or more inertial sensors to provide acceleration measurements for the GPS enabled device, and a GPS receiver to receive positioning data for the GPS enabled device. The GPS enabled device may also include a comparison logic to predict a position of the GPS enabled device from the acceleration measurements, and determine whether the received positioning data is within a confidence interval of the prediction.
