Resumen

The use of VANT (unmanned aerial vehicles) for the acquisition
of data from a specific geographical area allows its processing in
different processing software and its integration into GIS (geographic
information systems), allows to obtain different products
such as orthophotos, DEM (digital elevation models), topographic
profiles, etc. In order to obtain results with planimetric and
altimetric accuracy, it will be necessary to have ground control
points in some coordinate system, and the control points for the
verification of the results obtained.
The survey of points with three-dimensional coordinates can be
obtained with different methods and instruments, but in this
work we use GNSS techniques. Measurements taken with the
same GPS measurement equipment are compared, using the
RTK (Real Time Kinematic) measurement method and the NTRIP
(Networked Transport of RTCM method via Internet Protocol).
The objective is to carry out a comparative analysis of the coordinates
obtained in ten fixed points, with the two measurement
methods, and to provide information on their advantages and
disadvantages, for their usefulness in the processing of data
obtained with a VANT.
