Parameter Estimation with GNSS-Reflectometry and GNSS Synthetic Aperture Techniques
, 2018 Aside from intentional interference, multipath is the most significant error source for Global Navigation Satellite Systems (GNSS) receivers in many operational scenarios. In this thesis, we study the multipath estimation from two different perspectives: to retrieve useful information from it using GNSS-Reflectometry (GNSS-R) techniques; and to ...

Continuous Curvature Path Planning for Headland Coverage With Agricultural Robots
Journal of Field Robotics, Volume 42, Issue 3, Page 641-656, May 2025.ABSTRACT We introduce a methodology for headland coverage planning for autonomous agricultural robot systems, which is a complex problem often overlooked in agricultural robotics. At the corners of the headlands, a robot faces the risk to cross the border of a field while turning.

A Unified Topological Representation for Robotic Fleets in Agricultural Applications
Journal of Field Robotics, Volume 42, Issue 3, Page 760-786, May 2025.ABSTRACT Agricultural robots offer a viable solution to the critical challenges of productivity and sustainability of modern agriculture. The widespread deployment of agricultural robotic fleets, however, is still hindered by the overall system's complexity, requiring the integration of several nontrivial components for the operation of each robot but ...

Testing the Flyby Anomaly with the GNSS Constellation
, 2011 We propose the concept of a space mission to probe the so called flyby anomaly, an unexpected velocity change experienced by some deep-space probes using earth gravity assists.

Time-based GNSS attack detection [PDF]
To safeguard Civilian Global Navigation Satellite Systems (GNSS) external information available to the platform encompassing the GNSS receiver can be used to detect attacks. Cross-checking the GNSS-provided time against alternative multiple trusted time sources can lead to attack detection aiming at controlling the GNSS receiver time.

GNSS interference and spoofing dataset
Data in BriefGNSS signals are vulnerable to spoofing and interference, which poses a threat to the security of critical national infrastructure. GNSS data sets with spoofing and jamming are lacking, which hinders the research of GNSS anti-spoofing and anti-interference techniques.
