Multipath and non-line-of-sight (NLOS) signals are the major causes of poor accuracy of a
global navigation satellite system (GNSS) in urban areas. Despite the wide usage of the …

In recent years, the development of advanced systems and applications has propelled the
adoption of autonomous railway traffic and train positioning, with several ongoing initiatives …

Ubiquitous navigation requires timely, uninterrupted and accurate estimate of receiver's
position at all times, in all environments and for all modes of transportation and it is highly …

The berthing of an ultra large ship is always a difficult issue and becomes yet more complex
when vessels must be handled in restricted manoeuvring areas of limited depth, exposed to …

A twofold architecture based on GNSS multipath environment prediction and detection is
presented in a context of loosely coupled and tightly coupled IMU/GNSS integration for …

Accurate, ubiquitous and reliable navigation can make transportation systems (road, rail, air
and marine) more efficient, safer and more sustainable by enabling path planning, route …

With recent developments in global navigation satellite systems (GNSS), dual-and triple-
