    Gravity anomalies and lithospheric flexure around the Longmen Shan deduced from combinations of in situ observations and EGM2008 data

    The current work describes the combined data of three field campaigns, spanning 2009–2013. Their joint gravity and GPS observations thoroughly cover the sites of lithospheric flexure between the Sichuan Basin ...

    Development and examination of new algorithms of traveltime detection in GPS/acoustic geodetic data for precise and automated analysis

    A GPS/acoustic (GPS/A) geodetic observation technique allows us to determine far offshore plate motion in order to understand the mechanism of megathrust earthquakes. In this technique, the distance between a ...

    Effective expansion of satellite laser ranging network to improve global geodetic parameters

    The aim of this study is to find an effective way to expand the ground tracking network of satellite laser ranging on the assumption that a new station is added to the existing network. Realistic numbers of ob...

    The present-day number of tectonic plates

    The number of tectonic plates on Earth described in the literature has expanded greatly since the start of the plate tectonic era, when only about a dozen plates were considered in global models of present-day...

    A sequential and partial ambiguity resolution strategy for improving the initialization performance of medium-baseline relative positioning

    Ionosphere products that are relatively precise are available thanks to the efforts of the International GNSS Service (IGS), and it might be possible to obtain a high success rate for the fixed integer ambigui...
