    Geolocation systems have improved in accuracy thanks to technological advancements, redu- cing costs and expanding applications. RTK devices are highly accurate and useful in topo- graphic surveys, reliable in receiving GNSS signals. To lower costs, RTL-SDR devices were tested as GNSS receivers in a low-cost system configured as a rover connected to a base station using the RTCM protocol for differential corrections. Measurements were taken at eight reference points in Cuenca, comparing the accuracy of the processed signals under three con- ditions: without correction, with correction using an external base station, and with correction using a local base station. The results showed that the local base station improved accuracy, although in high-interference environments, the corrections were not always precise. Measure- ments without correction showed greater dispersion but a more accurate average. A low-cost SDR-based GNSS system is viable for moderate precision applications, with the local base station recommended for greater accuracy or no correction in high-interference environments.
