recommendations! Published in 2018 at "Journal of Geodesy"

DOI: 10.1007/s00190-018-1199-y

Abstract: A key limitation in the precise orbit determination (POD) of BeiDou geostationary Earth orbit (GEO) satellites is the relatively static observation geometry, which results in strong correlations between orbital elements, solar radiation pressure (SRP) parameters,… read more here.

DOI: 10.1080/2150704x.2018.1519272

Abstract: ABSTRACT Satellites-based microwave sensors are sensitive to soil moisture at the surface of the Earth, but their performance is limited by their continuously varying footprints due to the repeat cycle of satellites. In recent years,… read more here.

DOI: 10.1088/1402-4896/ad78c9

Abstract: Achieving high-precision positioning and fast convergence has been the objective of Precision Point Positioning (PPP), which is restricted by the integer ambiguity resolution (AR). Recently, the emergence of observable specific code/phase bias (OSB) has gratefully… read more here.

DOI: 10.1109/jstars.2023.3266875

Abstract: Owing to the global coverage and high visibility of global navigation satellite systems (GNSS), passive radar using GNSS satellites as transmitters of opportunity has shown great potential for moving target detection, and its possibility to… read more here.
