Özet

The increasing availability and affordability of low-cost Global Navigation Satellite System (GNSS)

systems have made them a viable alternative for various geospatial applications. However, their

performance and positioning accuracy require rigorous evaluation, especially when compared to

geodetic-grade GNSS systems. This study investigates the accuracy of low-cost GNSS systems in

positioning by comparing their results with those obtained from high-precision geodetic GNSS

systems.

To evaluate the performance of low-cost GNSS systems, campaign type GNSS measurements were

conducted at four points using both low-cost and geodetic GNSS systems. The collected data were

processed using the Canadian Spatial Reference System Precise Point Positioning (CSRS-PPP) and

the AUSPOS relative positioning services. The positioning results from these services were

analyzed to assess the performance of low-cost GNSS systems relative to their geodetic

counterparts. Preliminary findings indicate that low-cost GNSS systems exhibit promising accuracy

levels in comparison to geodetic systems. The results highlight the potential and limitations of lowcost

GNSS technology for scientific and practical applications.

This study contributes to the growing body of knowledge on low-cost GNSS technologies and

provides insights into their applicability in fields such as tectonic monitoring and geodetic

research. Future work will focus on refining processing techniques to further enhance the

reliability of low-cost GNSS systems.
