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.
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.
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.
The system architecture includes:
These mechanisms reduce service interruption risks and improve long-term operational stability.
