    • Abstract
  • Ionospheric delay is one of the main error sources in GNSS positioning.This paper describes a formula derived to correct higher-order ionosphere error of L3 observation and analyzed the effects on the static and kinematic positioning accuracy.Numerical results show that correcting the higher-order ionospheric error improves the PPP static and kinematic positioning accuracy and shorten the convergence time of PPP kinematic positioning.
