Focus FX Synthetic Base Station – FAQ Fact Sheet

What is the Focus FX Synthetic Base Station?

The Focus FX Synthetic Base Station is virtual GNSS infrastructure, generated from a surrounding network of physical CORS. Designed to eliminate the need for a nearby physical base station, it delivers high-accuracy real-time positioning using advanced atmospheric modelling and network correction techniques. This new approach enables survey-grade performance in areas where deploying traditional infrastructure is impractical, offering flexibility, scalability, and rapid deployment for modern GNSS workflows.

Key Benefits

  • No physical base hardware required onsite
  • Centimetre – level accuracy and improved precision – reducing height fluctuations
  • Rapid deployment for temporary or remote projects
  • Scalable across large geographic areas
  • Compatible with RTK grade GNSS rovers and NTRIP clients
  • Generates RINEX files and continually monitored

Typical Use Cases

  • Rapid deployment for construction and mining sites with no nearby infrastructure
  • Emergency or disaster mapping and re-establishment
  • Surveying in remote or infrastructure-sparse regions
  • Temporary GNSS deployments for short-term projects
  • Elimination of potential multipath or signal interference

Technical Requirements

  • Survey or GIS grade RTK GNSS rover
  • NTRIP client ideally supporting RTCM 3.x formats (MSM)
  • Reliable Internet connectivity (4G/5G or Starlink / Wi-Fi)
  • Subscription to AllDayRTK

Limitations

  • Dependent on adequate CORS coverage and CORS quality
  • May not meet Regulation 13 traceability for legal surveys
  • Accuracy and precision can vary in areas with poor geometry, multipath or quality
  • Requires a stable internet connection

Support and Integration

  • Managed by Aptella under the AllDayRTK network team
  • Integrates and supplements managed services and  Focus projects
  • API and mountpoint configurations available for enterprise users
  • New map feature to select suitable FX coverage areas
