High-Availability Network RTK Software for CORS Deployments
Modern GNSS correction services require more than positioning
algorithms alone. System reliability, scalability, and long-term
maintainability have become equally important factors in large
infrastructure projects.
PandaNRTK was developed with this operational perspective in mind.
The platform provides an integrated environment for managing GNSS
reference networks while supporting continuous real-time correction
services.
Multi-Constellation Processing Support
The system supports full-frequency processing across major
satellite constellations, including:
This multi-constellation capability allows correction services to
maintain stronger satellite availability and more stable
positioning performance under different operating environments.
Virtual Reference Station Technology
PandaNRTK incorporates VRS technology to generate correction data
tailored to user locations.
Instead of transmitting raw observation data externally, the
platform can generate encrypted virtual correction streams. This
design helps protect infrastructure data while allowing correction
services to scale across internet-based deployments.
Designed for Continuous Operation
The system architecture includes:
- distributed deployment support
- automatic fault recovery
- dynamic resource scaling
- real-time system monitoring
These mechanisms reduce service interruption risks and improve
long-term operational stability.
