G-ROX: Frequently asked questions and answers
Many high-precision GNSS applications depend on reliable RTK correction data. Commercial correction services often involve recurring subscription fees, limited availability or dependency on third-party infrastructure.
G-ROX solves these challenges by enabling organizations to operate their own RTK reference station. It generates high-quality RTCM correction data and distributes it securely through an integrated NTRIP service, providing full control over correction availability, scalability and long-term operating costs.
Commercial RTK correction services are convenient but often require ongoing subscription fees and depend on external providers and network availability.
G-ROX allows organizations to build and operate their own correction infrastructure. This eliminates recurring service costs, provides full ownership of correction data and supports unlimited rover devices through a scalable NTRIP service.
Organizations using multiple GNSS rovers can significantly reduce long-term costs by operating their own RTK correction infrastructure instead of paying recurring subscription fees for commercial services.
With G-ROX, one reference station can provide correction data for an entire fleet of rover receivers. This lowers the total cost of ownership while maintaining reliable centimeter-level positioning.
Yes. G-ROX can serve as a private alternative to commercial RTK correction services.
Instead of relying on external correction providers, G-ROX generates survey-grade RTCM corrections locally and distributes them through an integrated NTRIP caster. This provides full control over correction availability while reducing recurring operational costs.
A private RTK reference station is the right choice when reliable, long-term high-accuracy positioning is required across multiple GNSS rovers or critical applications.
Organizations benefit from greater independence, predictable operating costs, secure correction data and the flexibility to deploy corrections wherever they are needed.
G-ROX uses a survey-grade multi-frequency GNSS receiver to determine its precise reference position. After calibration via RTK or Galileo High Accuracy Service (HAS) PPP, the system continuously generates standard-compliant RTCM correction messages.
These corrections are streamed through the integrated NTRIP caster to connected rover receivers, enabling centimeter-level RTK positioning.
The integrated NTRIP caster securely distributes RTCM correction data over an IP network.
Authorized GNSS rover receivers connect to the caster using the NTRIP protocol and receive correction data in real time. This allows multiple rovers to share a single reference station while maintaining reliable and consistent RTK performance.
RTK calibration determines the reference station position using corrections from an existing RTK network, allowing fast deployment where correction services are available.
PPP (Precise Point Positioning), such as Galileo HAS, determines the reference position independently using precise satellite correction data. This enables G-ROX to be deployed without requiring an external RTK infrastructure.
Yes, depending on the deployment scenario.
G-ROX can generate RTK correction data locally. Internet access is only required if cloud-based correction distribution or Galileo HAS PPP calibration is used. Local RTK correction services within a private network can operate without permanent internet connectivity.
