(author), Ghazali, Zaki (author), Darani Rahman, Wan (author), Cob, Sanusi (author), Kadir, Majid (author), Bin Mustafar, M.A. (author), Din, Ami Hassan (author), Efendi, Joni Efendi (author), Noppradit, Prakrit (author)Absolute sea-level rise has become an important topic globally due to climate change. In addition, relative sea-level rise due to the vertical land motion in coastal areas can have a big societal impact. Vertical land motion (VLM) in Southeast Asia includes a tectonically induced component: uplift and subsidence in plate boundary zones where...journal article 2023

Xiong, Chao (author), Xu, Ji Sheng (author), Stolle, Claudia (author), van den IJssel, J.A.A. (author), Yin, Fan (author), Kervalishvili, Guram N. (author), Zangerl, Franz (author)Transient signal loss of the global positioning system (GPS) has been frequently observed by receivers on board the European Space Agency's Swarm mission when the satellites encounter ionospheric plasma irregularities. In this study we provided the first comparison of the GPS signal amplitude degradations from receivers on board low Earth...journal article 2020

Ma, H. (author), Zhao, Qile (author), Verhagen, S. (author), Psychas, D.V. (author), Liu, Xianglin (author)The benefits of an increased number of global navigation satellite systems (GNSS) in space have been confirmed for the robustness and convergence time of standard precise point positioning (PPP) solutions, as well as improved accuracy when (most of) the ambiguities are fixed. Yet, it is still worthwhile to investigate fast and high-precision...journal article 2020

De Bakker, P.F. (author)Precise Point Positioning (PPP) is a Global Navigation Satellite System (GNSS) processing method with the objective of providing high positioning accuracy without the need for a nearby base station or dense network of reference stations operated by the user. To reach this objective, PPP uses the very precise carrier phase measurements in...doctoral thesis 2016

Zhang, B. (author), Teunissen, P.J.G. (author), Odijk, D. (author)In this contribution, a novel un-differenced (UD) (PPP-RTK) concept, i.e. a synthesis of Precise Point Positioning and Network-based Real-Time Kinematic concept, is introduced. In the first step of our PPP-RTK approach, the UD GNSS observations from a regional reference network are processed based upon re-parameterised observation equations,...journal article 2011
