Abstract
Location determination using the global positioning system (GPS) can suffer from signal quality issues caused by multipath effects or signal fading, as well as device-specific GPS-signal integration techniques. Accurate location determination is important for many user tasks. This disclosure describes techniques that enable users to automatically obtain accurate location based on the most accurate location measure among all available devices by using the device(s) with the least noisy GPS signal. Unsupervised clustering of data from device motion sensors can be employed to determine the available devices. Impulse characterization can be used to measure the quality of the location signal by taking into account various noise-inducing factors and to select the device(s) for obtaining the most accurate location determination.
