Local troposphere augmentation for real-time precise point positioning [PDF]

open access: yesEarth, Planets and Space, 2014
The IGS real-time service (RTS) enables real-time precise point positioning (PPP) at a global scale. A long convergence time however is still a challenging factor. In order to reduce the convergence time, external troposphere corrections could be introduced to remove the troposphere effects on the coordinate solution.
