Abstract

GNSS typically suffer from reduced precision of the height component due to the pseudo-range concept. Thanks to advances in clock technology it has bee shown that a physically meaningful modeling of the receiver clock behavior rather than an epoch-by-epoch estimation can significantly improve code-based navigation. In this contribution, a simulation study is carried out in order to investigate the benefits of receiver clock modeling (RCM) in kinematic precise point positioning (PPP) using a passive hydrogen maser (PHM). As a result, the precision of the vertical coordinate and velocity estimates is improved by approximately 70%. Furthermore, internal and external reliability are enhanced, thus the estimation process becomes more robust against observation outliers. However, in the current implementation the estimated real-valued ambiguity and troposphere parameters are not affected by clock modeling in the simulation study. The theoretical considerations are then expanded to a practical application. Thus, preliminary results of a real kinematic experiment using a passive hydrogen maser are presented and discussed. The corresponding results are very close to those of the simulation study, i.e. they confirm the potential of receiver clock modeling in kinematic PPP, highlighting the representativity of the simulated scenarios.
