Análisis de la técnica de corrección de posicionamiento preciso “RTK” utilizando sistemas de navegación multiconstelación para analizar la precisión en la posición final (PVT).

Abstract

The study objective of the present work was to analyze the new existing technologies of positioning. The use of multi-constellation and the GNSS systems in the massive market of applications were implemented to obtain a precise positioning. Since most receivers only use GPS or GLONASS, it limits the applications they can perform on the market. That is why employing the ZED F9P module (which supports multi-constellation) on the C099-F9P card. The precision obtained by the constellations of GPS, GLONASS, Galileo, BeiDou, connected via NTRIP to the base stations, is analyzed—offered by REGME. Through three scenarios tested, the final precision was obtained with ta eta in real-time. Using this table represents a significant advance in terms of low-cost real-time positioning systems due to the card's advantages and the fact that all parameters are configurable. It has been possible to verify current precise positioning systems through this module linked to the Ambato ABEC3 base station by NTRIP. Corrections are received in RTCM 3.0 format, which is used so that the application table, through the status of the link's representation, obtains corrections in real-time of the pseudorandom and carrier phase. Thus, achieving similar accuracies of high-precision geodetic equipment such as the Spectra SP60, having resulted of 10mm to 20mm regarding the positioning of the same, but with a high lower budget, even indoors, achieving better precision. Finally, to check the precision in natural environments, the Pix4D software was post-processing. Thus, the importance of using precise positioning systems is evidenced.
