A framework for opportunistic navigation with multi-constellation low Earth orbit (LEO)
satellite signals is proposed. A receiver architecture suitable for processing both time …

Abstract The Low Earth Orbit (LEO) satellites can be used to effectively speed up Precise
Point Positioning (PPP) convergence. In this study, 180 LEO satellites with a global …

A framework to exploit megaconstellation low Earth orbit (LEO) satellite signals of
opportunity for navigation is developed. This framework, termed simultaneous tracking and …

I am not afraid of the GPS jammer, as long as there are ambient signals of opportunity
(SOPs) to exploit in the environment. In environments where GPS signals are challenged …

A navigation framework with carrier phase differential measurements from
megaconstellation low Earth orbit (LEO) satellite signals is developed. The measurement …

A Doppler tracking and beacon detection framework for blind opportunistic navigation (BON)
with low Earth orbit (LEO) satellite signals is proposed. The BON framework cognitively …

A framework that could achieve submeter-level-accurate horizontal navigation with carrier
phase differential measurements from cellular signals is developed. This framework, termed …

This paper shows the first results of differential Doppler positioning with unknown low Earth
orbit (LEO) Star-link satellite signals. To this end, a receiver capable of acquiring and …

Machine learning (ML) frameworks are investigated for use in simultaneous tracking and
navigation (STAN) with low Earth orbit (LEO) satellites. STAN is a navigation paradigm that …

A hybrid analytical-machine learning (ML) framework for improved low Earth orbit (LEO)
satellite orbit prediction is developed. The framework assumes the following three stages.(i) …
