MULTI-GNSS RECEIVER FOR AEROSPACE NAVIGATION AND POSITIONING APPLICATIONS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 The upcoming Galileo system opens a wide range of new opportunities in the Global Navigation Satellite System (GNSS) market. However, the characteristics of the future GNSS signals require the development of new GNSS receivers.

The Crab pulsar seen with Aqueye at Asiago Cima Ekar Observatory [PDF]
, 2010 We are developing fast photon-counter instruments to study the rapid variability of astrophysical sources by time tagging photon arrival times with unprecedented accuracy, making use of a Rubidium clock and GPS receiver. The first realization of such optical photon-counters, dubbed Aqueye (the Asiago Quantum Eye), was mounted in 2008 at the 182cm ...

A gravitational redshift test using eccentric Galileo satellites [PDF]
Physical Review Letters, Vol. 121, Iss. 23, p. 231101, 7 December
2018, 2018 We report on a new test of the gravitational redshift and thus of local position invariance, an integral part of the Einstein equivalence principle, which is the foundation of general relativity and all metric theories of gravitation. We use data spanning 1008 days from two satellites of Galileo, Europe's global satellite navigation system (GNSS ...

Probing the Flyby Anomaly with the future STE-QUEST mission [PDF]
Planetary and Space Science, Volumes 79-80, May 2013, Pages 76-81, 2012 In this study, we demonstrate that the flyby anomaly, an unexpected acceleration detected in some of the gravitational assists of the Galileo, NEAR, Cassini and Rosetta spacecraft, could be probed by accurate orbital tracking available in the proposed Space-Time Explorer and Quantum Equivalence Principle Space Test (STE- QUEST); following a recent work,

Robust Modeling of GNSS Orbit and Clock Error Dynamics
Navigation, 2022 In this paper, we develop new stochastic orbit and clock error models for positioning, fault detection, and integrity monitoring over time. GPS and Galileo orbit and clock data are evaluated and ranging errors are analyzed and modeled over time.
