METHOD AND APPARATUS FOR DECENTRALIZED GNSS CORRECTION INFORMATION GENERATION

摘要

PURPOSE: A dispersed correction information generating apparatus of a GNSS(Global Navigation Satellite System) is provided to flexibly estimate lively activity of an ionization layer in real time while reducing the burden of calculation amount and communication amount. CONSTITUTION: An exclusive module(10) receives measurement information of a GNSS satellite from an individual receiver. The exclusive module calculates an estimation value of an absolute value of error elements including ionization layer delay and mixed inter-frequency bias and provides dispersion information. A fusion module(30) is connected to the exclusive module and unites the estimation value of the absolute value of the error elements in the dispersion information. The fusion module creates an ionization layer map.
