Hou, P. (author), Zha, Jiuping (author), Liu, Teng (author), Zhang, Baocheng (author)Precise point positioning-real-time kinematic (PPP-RTK), otherwise known as integer ambiguity resolution-enabled precise pointing positioning, has attracted much attention in recent years and has become state-of-the-art in the global navigation satellite system (GNSS) high-precision positioning community. This work reviews several PPP-RTK...journal article 2023

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

Psychas, D.V. (author), Verhagen, S. (author), Liu, X. (author), Memarzadeh, Y. (author), Visser, H. (author)This paper presents an analysis of the ionospheric corrections required to get a significant improvement in PPP-RTK performance. The main aim was to determine the improvement in the position precision and Time-To-First-Fix in the PPP-RTK user side using ionospheric corrections computed from a network. The study consists of two main steps. The...journal article 2019
