Psychas, D.V. (author)Precise Point Positioning (PPP) is a Global Navigation Satellite Systems (GNSS) modelling and processing method that provides single-receiver users with high positioning accuracy anywhere on the globe, without the explicit dependence on reference receivers. The realization of PPP is based on undifferenced code and phase measurements, a priori...doctoral thesis 2022

Ma, H. (author), Verhagen, S. (author), Psychas, D.V. (author), Monico, João Francisco Galera (author), Marques, Haroldo Antonio (author)The technology of integer ambiguity resolution-enabled precise-point-positioning (also referred to as PPP-AR) has been proven capable of providing comparable accuracy, efficiency, and productivity to long-baseline real-time kinematic positioning (RTK) during the last decade. Commercial PPP-AR services have been provided by different...journal article 2021

Psychas, D.V. (author), Teunissen, P.J.G. (author), Verhagen, S. (author)The single-receiver integer ambiguity resolution-enabled variant of precise point positioning (PPP), namely PPP-RTK, has proven to be crucial in reducing the long convergence time of PPP solutions through the recovery of the integerness of the user-ambiguities. The proliferation of global navigation satellite systems (GNSS) supports various...journal article 2021

Zhang, Baocheng (author), Teunissen, P.J.G. (author), Yuan, Yunbin (author), Zhang, Hongxing (author), Li, Min (author)Vertical total electron content (VTEC) parameters estimated using global navigation satellite system (GNSS) data are of great interest for ionosphere sensing. Satellite differential code biases (SDCBs) account for one source of error which, if left uncorrected, can deteriorate performance of positioning, timing and other applications. The...journal article 2018
