GNSS PPP-AR utilizing local SSR corrections

Original language description

Precise Point Positioning (PPP) and Network Real-Time Kinematic (NRTK) have historically been known as two independent precise positioning techniques due to their respective evolutions and applications. While both rely on a network of stations to estimate corrections to be broadcast to the user, PPP uses a global network while NRTK uses a local network. The local nature of NRTK allows access to precise atmospheric corrections, which enables real-time, instantaneous, centimeter-level user positioning. However, fundamental differences exist between PPP and NRTK corrections. In this work, the unexplored possibility of using state-space representation (SSR) local NRTK corrections in an ambiguity-resolved PPP (PPP-AR) solution is assessed. Novel research results show that instantaneous ambiguity resolution can indeed be consistently achieved in a PPP-AR engine, where GNSS corrections are only estimated from a local network without global constraints from a global solution. The results are preceded by an in-depth and insightful analysis of differences between NRTK and PPP at both the SSR correction and position levels. The analysis presented here is insightful and necessary to open the door for a convergence of PPP and NRTK thanks to the possibility of processing GNSS corrections from a local network in a PPP-AR engine, which may eventually lead to a more robust and hybrid NRTK/PPP solution. Such a hybrid solution could potentially be useful in challenging areas for PPP such as dense urban environments.
