Dr. Sunil Bisnath, York University, Toronto, Canada, presented On the future of Precise Point Positioning
Abstract
The Precise Point Positioning (PPP) GNSS data processing technique has grown from humble beginnings in the 1990s to the de facto standard for positioning, navigation and timing (PNT) applications in open sky, remote regions with limited socioeconomic densities. This talk will discuss some of the key issues leading to the success of PPP, including correction products and measurement modelling, and will investigate its key performance limitations, including accuracy, filter convergence period and robustness. Our current and near-term ability to mitigate these problems will be reviewed. And the context of PPP usage within precise GNSS positioning and, more generally, commercial GNSS PNT solutions, will be considered.
