Protocols and formats for the dissemination of GNSS data (global navigation satellite system): a review
Keywords:
GNSS, data transmission, protocols, formatsAbstract
In 1998, in line with the international trend, the National Geographic Institute of Argentina (IGN) in partnership with various national public institutions initiated a project for the installation of a series of GPS/GNSS (Global Positioning System/Global Navigation Satellite System) permanent stations across their national territory. At the present time, this Argentine Network of Continuous Satellite Monitoring (RAMSAC) is composed of 64 Continuous Stations (EC) that materialize the Geodetic Reference Frame ITRF-2005 (Epoch 2006.632). The sustainable development and the reliability of this RAMSAC network, along with the evolution of applications and possibilities associated with the Internet (particularly the techniques of data transmission via the Internet Protocol through the division of data into appropriate sizes) have enabled the implementation of a real-time correction system based on the data provided by these Continuous Stations. The methodology applied is based on the development elaborated by the Federal Agency for Cartography and Geodesy of the Federal Republic of Germany (BKG) broadcast under the name Networked Transport of RTCM via Internet Protocol (NTRIP). It allows multiple users to obtain, in real-time, coordinates (latitude, longitude and height) with sub-meter accuracy levels. This article summarizes the various modes of real-time GNSS data delivery in terms of transmission protocols, data formats, links of communication, structure of messages, and content between different versions of the RTCM SC-104 formats (Radio Technical Commission for Maritime Services - Special Committee 104), including recent amendments.
