  • It is the official national CORS network, supporting the country’s geodetic reference system.

Availability & access

  • CROPOS is a paid subscription service, offered to surveyors, engineers, and other professional users.
  • Access is provided through NTRIP for real-time corrections and via the CROPOS portal for RINEX data downloads.

Coverage & scale

  • The network covers the entire territory of Croatia with a dense distribution of stations.
  • It is integrated into the broader European Position Determination System (EUPOS) and aligned with the European Terrestrial Reference System (ETRS89).

Typical use cases

  • Cadastral surveying and property registration.
  • Engineering and construction projects requiring centimeter accuracy.
  • GIS mapping for municipalities and infrastructure planning.
  • Agricultural applications where precision guidance is needed.

How it’s used in practice

  • Surveyors connect GNSS rovers to the CROPOS NTRIP service for RTK corrections.
  • Post-processing is supported with downloadable RINEX files for static and kinematic workflows.

Notes

  • CROPOS is considered one of the most advanced CORS networks in the Balkans.
  • It provides reliable, high-quality data and plays a central role in modernizing Croatia’s geospatial infrastructure.
