DMB/NTRIP Method for differential correction and position error estimation of GNSS and provision of AIS information via DMB/NTRIP

摘要

The present invention relates to a satellite navigation correction method capable of obtaining improved positional accuracy using a TPEG message provided through a terrestrial DMB (Digital Multimedia Broadcasting) data channel and RTCM correction information through NTRIP, which is an Internet-based RTCM standard, And a method for estimating the error level. Also, the present invention provides an AIS message collected from a specific port to a ship user through a TPEG message and a NTRIP provided through a terrestrial DMB (Digital Multimedia Broadcasting) data channel, and based on this, The present invention relates to a DMB-based ship automatic identification information providing method.
