Yıldız Technical University Turkey

Obtained his PhD from Newcastle University, UK. Studied sea level rise using GPS in his PhD thesis. In particular, specialized in vertical crustal deformation monitoring using GPS. Then moved into the area of GPS positioning accuracy. Managed to model both vertical and horizontal accuracy for relative-PPP and PPP. He also studied GPS positioning accuracy for rapid-static positioning for BERNESE and OPUS-RS software. On the other hand, he continued co-authoring sea level studies. He was involved in NEAMTWS Tsunami Warning efforts under the auspices of UNESCO. He was a member of Sea Level Working Group 3. Currently he is interested in assessing the accuracy of GPS positioning velocities with the focus on PPP derived positions from repeated GPS surveys.

Following the GPS, new GNSS techniques are emerging today. Various surveying and processing methods are available for the analysis of GNSS data. Equipment and software are also varied. The orbit quality, controlled by the system designer, and the IGS are continuously improved. The user is mainly interested in the quality of position and of the deformation rates produced by the GNSS. Hence, research needs to guide the user in terms of selecting the best combination of the available methods and instrumentation to produce the desired accuracy. This book reviews the current available accuracy obtainable using the GNSS methods. In fact, the main aim of this book is to make an impact on young researchers so that they keep updating the accuracy of GNSS for future generations.
