Multi-GNSS precise point positioning for precision agriculture [PDF]

open access: yesPrecision Agriculture, 2018
The main objective of this research was to examine the feasibility of Multi-GNSS precise point positioning (PPP) in precision agriculture (PA) through a series of experiments with different working modes (i.e. stationary and moving) under different observation conditions (e.g. open sky, with buildings or with canopy).

Precise Point Positioning with Kepler [PDF]

open access: yes2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019
Precise Point Positioning (PPP) enables an absolute positioning with centimeter-level accuracy without the need of raw measurements from a reference station. However, today's GPS L1/ L2-based PPP solutions typically need more than 30 minutes to converge.
