A Novel Single Differencing Measurement for Multipath Detection (2023)
Journal Article

Increased global dependence on Global Navigation Satellite Systems (GNSSs) has resulted in a high demand for greater precision and reliable measurements from GNSS receivers. The multipath problem is the single largest source of errors in modernised G... Read More about A Novel Single Differencing Measurement for Multipath Detection.

Methodology for optimizing a Constellation of a Lunar Global Navigation System with a multi-objective optimization algorithm (2023)
Journal Article

Global Navigation Satellite Systems (GNSS) are not only used in terrestrial applications, but also in Low-Earth orbit satellites and in higher altitude missions. NASA's Magnetospheric Multiscale (MMS) mission has demonstrated the capabilities of exis...

Performance Analysis of Zero-Difference GPS L1/L2/L5 and Galileo E1/E5a/E5b/E6 Point Positioning Using CNES Uncombined Bias Products (2022)
Journal Article

The modernization of Global Navigation Satellite System (GNSS) including the transmission of signals on multiple frequencies has greatly promoted the development of the popular PPP (Precise Point Positioning) technique. A key issue of multi-frequency... Read More about Performance Analysis of Zero-Difference GPS L1/L2/L5 and Galileo E1/E5a/E5b/E6 Point Positioning Using CNES Uncombined Bias Products.

An Introduction to the HydroGNSS GNSS Reflectometry Remote Sensing Mission (2021)
Journal Article

HydroGNSS (Hydrology using Global Navigation Satellite System reflections) has been selected as the second European Space Agency (ESA) Scout earth observation mission to demonstrate the capability of small satellites to deliver science. This article... Read More about An Introduction to the HydroGNSS GNSS Reflectometry Remote Sensing Mission.

Orbital Filter Aiding of a High Sensitivity GPS Receiver for Lunar Missions (2017)
Journal Article

Recent studies have shown that weak global navigation satellite system (GNSS) signals could potentially be used to navigate from Earth to the Moon. This would increase autonomy, robustness, and flexibility of the navigation architectures for future l... Read More about Orbital Filter Aiding of a High Sensitivity GPS Receiver for Lunar Missions.
