Evaluación de la precisión del posicionamiento en tiempo real usando la tecnología Trimble RTX en la ciudad de Bogotá

Abstract

This document shows the results of the verification of the accuracy of the Trimble RTX technology in the city of Bogotá. To assess the accuracy of this technology, established a network with 10 control points belonging to the passive GNSS network of the Institute Geographic Agustín Codazzi (IGAC) in which at each point positioning of NTRIP and RTX with two sessions, the first lasting 5 seconds and the second lasting 10 seconds, one session of PPK in compliance with the specifications of resolution 643 of 2018, a minimum tracking time of 5 minutes these data were taken with a CHC I90 Pro receiver and at one point RTK was performed with a tracking time of 5 seconds with a pair of receivers CHC I80. Carrying out the corresponding post-processing, time change and projection conversion mapping to the single national origin, it was possible to make a comparison with the difference of coordinates between the positioning methods taking as reference the coordinates of the IGAC. This made it possible to determine if the details offered by the supplier of the service, its advantages and disadvantages.
