On the Evaluation of Confidence Levels with Application to GNSS

open access: yesION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2020
The goal of this contribution is to assess the impact statistical model selection has on confidence levels of parameter estimators in linear(ized) GNSS models. In the processing of observational data, parameter estimation and statistical testing are often combined. A testing procedure is exercised to select the most likely observational model among the

Urban Road Safety Prediction: A Satellite Navigation Perspective [PDF]

open access: yes, 2022
Predicting the safety of urban roads for navigation via global navigation satellite systems (GNSS) signals is considered. To ensure safe driving of automated vehicles, the vehicle must plan its trajectory to avoid navigating on unsafe roads (e.g., icy conditions, construction zones, narrow streets, etc.). Such information can be derived from the roads'
