Ultra-wideband (UWB) Localization for Autonomous UAV Flight in GNSS-denied Environments

Open-source GNSS Direct Position Estimation Plug-in Module for MATLAB-based Two-step Positioning Software Defined Receivers

Localization of a GNSS denied UAV relative to a Moving Local Reference Frame in an Offshore Environment

Open-source GNSS Multipath Mitigation Technology-integrated Direct Position Estimation for Urban Navigation

This exercise focuses on processing Global Navigation Satellite Systems (GNSS) data, particularly emphasizing double differences (DD) and cycle slip detection. The dataset provided represents a static GPS measurement campaign conducted in a densely populated urban environment, comprising five stations labeled HH01 to HH05.
