Direct GPS Positioning (DP) is a robust method that estimates the GPS navigation solution
directly from the received GPS signal. In contrast, traditional methods, such as scalar …

Direct Position Estimation (DPE) is a rather new Global Navigation Satellite System (GNSS)
technique to estimate the user position, velocity and time (PVT) directly from correlation …

This chapter presents an innovative concept that helps overcome some of the critical
challenges and limitations in standard global navigation satellite system (GNSS) position …

This study addresses the problem of geolocating a strictly non‐circular source on the surface
of Earth by a cluster of passive satellites. The known satellite positions and velocities are …

Abstract Global Positioning System (GPS) receivers are increasingly used for positioning in
urban environments and precise timing in critical infrastructures. These scenarios are …

In the last decades, the Global Navigation Satellite Systems (GNSSs) became fundamental
for several applications such as pedestrian, automotive, maritime, air and so on [1]. Despite …

Image search engines commonly employ the Bag Of Features (BOF) method to represent
each database image with a feature vector and retrieve the best candidate using a measure …

Bayesian Direct Position Estimation (BDPE) is a novel and promising positioning method,
where the Position, Velocity and Time (PVT) is estimated directly from the correlation values …
