Who operates it
- SmartNet in Bulgaria is operated by Leica Geosystems, providing commercial GNSS correction services.
- RTK Direct is a private provider delivering subscription-based RTK solutions within the Bulgarian market.
Availability & access
- Both networks are paid services, typically offered on monthly or annual subscriptions.
- Corrections are streamed via NTRIP and are compatible with most professional GNSS equipment.
Coverage & scale
- Nationwide coverage across Bulgaria, with dense reference station placement to ensure accuracy.
- Both networks contribute to the broader European GNSS infrastructure and align with continental geodetic frames such as ETRF and EUPOS.
Typical use cases
- Cadastral and land surveying with centimeter-level accuracy.
- Civil engineering, construction, and infrastructure monitoring projects.
- Agricultural machine guidance and precision farming.
- GIS and municipal planning applications.
How it’s used in practice
- Surveyors connect their GNSS rovers to SmartNet or RTK Direct NTRIP casters for real-time RTK corrections.
- Professionals can also log GNSS data for post-processed solutions when needed.
Notes
- Commercial networks are preferred in Bulgaria due to their reliability, professional technical support, and compatibility with modern surveying instruments.
- They serve as the main alternative to a fully state-operated CORS infrastructure.
