Future autonomous transportation is one of the most demanding application areas in terms
of connectivity, as it has to simultaneously meet stringent criteria that do not typically go …

The ground-based augmentation system (GBAS) is the cornerstone for enabling automated
landings without the instrument landing system (ILS). Currently, GBAS is evolving to GBAS …

The incorporation of multiple constellations into satellite based augmentation systems
(SBAS) may lead to cases where there are more corrected satellites in view than a receiver …

When incorporating multiple constellations into future ground based augmentation systems
(GBAS), a problem with limited VDB (VHF data broadcast) capacity might arise. Furthermore …

In this work an overview of numerous possible processing modes in future dual frequency,
dual constellation GBAS is given and compared to the current GAST D standard. We discuss …

Code phase Global Navigation Satellite System (GNSS) positioning performance is often
described by the Geometric or Position Dilution of Precision (GDOP or PDOP), functions of …

GNSS receivers convert the measured pseudoranges from the visible GNSS satellites into
an estimate of the position and clock offset of the receiver. For various reasons receivers …

A set of fast optimization-based procedures for the selection of an optimal subset of satellites
from those within view of a receiver is provided. Resource limitations, the low marginal utility …

Satellite selection is an effective way to overcome the challenges for the processing
capability and channel limitation of the receivers due to superabundant satellites in view …

The number of feature points on the surface of a non-cooperative target satellite used for
monocular vision-based relative navigation affects the onboard computational load. A …
