A method for improved stand-alone global navigation satellite system (GNSS) performance

摘要

This disclosure relates to improving performance in devices implementing standalone global navigation satellite system (GNSS) receivers.Specifically, the GNSS compliant mobile device can obtain positioning data from one or more non satellite sources and determine satellite signal quality in the ambient environment.ThereforeIn response to determining the environment surrounding GNSS mobile devices as a weak satellite signal environmentGNSS mobile devicesPerformance in devices implementing a standalone GNSS receiver can be enhanced in environments of poor satellite signalsA process for providing positioning data acquired from one or more non satellite sources to a device implementing the standalone GNSS receiver may be triggered.
