Spaceborne Global Navigation Satellite Systems (GNSS) receivers have become ubiquitous
sensors for spacecraft navigation, especially in Low Earth Orbits (LEOs), often also …

The steady increase in the number of elderly citizens represents a likelihood of an increased
burden on the family, government, healthcare, and social services since many of these …

This paper summarizes current state-of-the-art navigation results with multi-constellation low
Earth orbit (LEO) satellite signals of opportunity. Experimental results with four LEO satellite …

In a typical GNSS receiver, pseudorange and pseudorange rate measurements are
generated through the code and carrier tracking loops, respectively. These measurements …

Positioning, Navigation and Timing (PNT) are services generally provided by Global
Navigation Satellite Systems (GNSS). GNSS reside in medium to high orbital altitudes from …

Future Internet of Things (IoT) will be a connected network of sensors enabling applications
such as industrial automation and autonomous driving. To manage such a large number of …

Acquisition and tracking of Starlink low Earth orbit (LEO) satellite signals in low signal-to-
noise ratio (SNR) regime is considered. Starlink's highly dynamic downlink LEO signal …

A spectral approach for blind acquisition and Doppler tracking of low Earth orbit (LEO)
