Modern smartphones contain a number of sensors that can be used for navigation when GPS signals are unavailable. Low cost MEMS gyros and accelerometers are increasingly becoming available in modern devices, however when used for positioning, they typically result in large errors after very short periods of time. This paper investigates using measurements(More)
The deployment of Galileo and the modernization GPS will provide additional signals with increasingly complex modulations and multiplexing schemes, enabling performance enhancements in terms of availability, accuracy, and robustness. With the Galileo Initial Operational Capability (IOC) scheduled around mid-decade with fourteen satellites already ordered in(More)
