The integration of Global Navigation Satellite System (GNSS) integrity augmentation functionalities in Unmanned Aerial Systems (UAS) has the potential to provide an integrity-augmented Sense-and-Avoid (SAA) solution suitable for cooperative and non-cooperative scenarios. In this paper, we evaluate the opportunities offered by this integration, proposing a novel approach that maximizes the synergies...
Indoor positioning is one of the biggest challenges of many Location Based Services (LBS), especially if the target users are pedestrians, who spend most of their time in roofed areas such as houses, offices, airports, shopping centres and in general indoors. Providing pedestrians with accurate, reliable, cheap, low power consuming and continuously available positional data inside the buildings (i...
Low cost MEMS sensors have been shown to provide high accuracy positioning when mounted on a user's foot through the use of zero velocity updates (ZUPT) every time the user takes a step. Although position drift is greatly reduced using ZUPTs, position errors will still accumulate over time, particularly due to heading errors which are weakly observable through zero velocity updates. Measurements from...
