Precise multi-GNSS point positioning: theory, algorithm and data analysis

Abstract

In this thesis we study the principles and intricacies of the new state-of-the-art precise positioning technique, the PPP-RTK. Both its network- and user-components are discussed. The concept of array-based PPP-RTK is introduced, where its efficiency is demonstrated by multi-Global Navigation Satellite Systems (GNSS) results. Finally an optimal recursive filter is developed to process observation equations of the network- and user-components.
