Many high-precision GNSS applications depend on continuous, reliable RTK correction data. Commercial correction services often involve recurring subscription costs, limited flexibility and dependency on external providers. G-ROX addresses these challenges by enabling organizations to operate their own high-quality RTK reference station infrastructure. As a cloud-based RTCM service, it delivers reliable correction data independently of third-party network policies, ensuring maximum availability, full control over correction generation and distribution, and optimal RTK positioning performance without ongoing service provider costs.

Overview G-ROX

Two different versions of G-ROX are available:

  • G-ROX PRO
  • G-ROX SMART
  • Integrated Multi-frequency, Multi-GNSS receiver
  • Integrated NTRIP client. Compliant with newest RTCM 3.X standards
  • Cloud-hosted NTRIP caster for streaming RTCM corrections to rovers (MS-RTK modules)
  • Calibration of RTCM reference station either via service provider or internal PPP solution (with Galileo HAS)
  • 1x GigabitEthernet
  • 1x WiFi
  • 1x 5G 2×2 MIMO
  • 2x USB 3.1

The G-ROX RTK reference station provides correction data in standard RTCM 3.X format to guarantee precise positioning in every situation without any integration effort. It only requires a power supply and connected GNSS antenna, thus it is ready to use after a short calibration phase.

The reference station can be initially calibrated using two technologies:

  • With RTK correction from an external provider or existing ANavS G-ROX stations nearly
  • With PPP correction data, either from Galileo High Accuracy Service (HAS) by satellite signal or HAS-IDD source (terrestrial link), both free of
    charge

The G-ROX system is built on a new modular hardware platform, delivering improved processing capabilities and upgraded interfaces. The system comes with a survey-grade multi-frequency, multiconstellation GNSS receiver. A powerful configuration and visualization software is implemented as a web app, easily accessible from different kinds of devices, including laptops and tablets. It is directly hosted on the system with no need for installation of software on your device.
