摘要：
We describe a hybridized receiver architecture tightly coupled with different sensors, namely MEMS accelerometers and gyroscopes, Wi-Fi engine and a barometer, allowing significant increase of positioning performance for indoor GNSS signal reception. This is possible due to the increase of integration times, use of higher sensitivity GNSS receivers and by resorting to external aiding sensors tightly coupled with the receiver. Expected overall navigation performance increase is described and the benefits of using such external sensors are quantified. Indeed, hybridization of GNSS receivers with other sensors is expected to be a key technology that will enable new services and applications for the use of GNSS for navigation in indoor and densely urbanized environments.
