Análisis e implementación de diferencial de GPS en tiempo real a través de la tecnología NTRIP para la EERSA.

Abstract

The objective of the research was to analyze the correction of errors in real time of Global Positioning System (GPS) recipients using Ntrip technology, to determine if post-processing in data collection positioning can be avoided, as hypothesis, implemented a NtripServer and connecting the Ntripclients to the third generation mobile network (3gd) through the TCP / IP protocol can correct the positioning errors in real time. The operation consists of a system based on: RTCM to the Ntripserver, being the reference satellite stations responsible for transmitting RTCM and Ntripclients data conformed by the GPS receivers and the experimental method configured the Ntripcaster and the connection with the GPS receivers to establish communication between devices Using the techniques of observation and data acquisition of positioning, an improvement in the positioning data was obtained and a greater precision. According to the comparison between the values obtained in an autonomous way and by means of the use of NTrip technology it was confirmed that the technology Ntrip can avoid post-processing, thus reducing costs in the company. To obtain satisfactory results will depend on many factors among which are: the distance to the reference station, type of geographic density and the type of climate. For which to get the best results is recommended to perform tests in a temperate environment.
