Atlas® GNSS Global Correction Service

Atlas® GNSS Global Correction Service

Scalable, Global GNSS Correction Service for All High-Precision Applications

Atlas is an innovative, industry-leading GNSS-based global L-band correction service, providing robust performance at competitive market prices. Atlas is a flexible and scalable service, delivering its correction signals via L-band satellites at accuracies ranging from meter to sub-decimeter levels. Leveraging more than 200 reference stations worldwide and with L-band satellites distributing Atlas corrections, the entire globe is virtually covered. The Atlas GNSS global correction service provides correction data for GPS, GLONASS, BeiDou, and Galileo constellations.

Atlas correction service is available on all Hemisphere Atlas-capable single- and multi-frequency, multi-GNSS hardware. Atlas complements third-party GNSS receivers by allowing them to use Atlas corrections with Hemisphere’s innovative BaseLink® and SmartLink™ capabilities.

Industry-Leading Capabilities

  • Positioning Accuracy: Atlas provides competitive positioning accuracies down to 4 cm RMS in certain applications, often exceeding competitive systems’ capabilities
  • Positioning Sustainability: Cutting-edge position quality maintenance in the absence of correction signals, using Hemisphere’s Tracer™ technology
  • Convergence Time: Industry-leading convergence times of 10 – 40 minutes
  • Global Ionospheric Model: Real-time ionospheric activity and data is sent to the receiver and allows Atlas-capable devices to adjust accordingly, providing excellent convergence performance

Scalable Service Levels
Service Level – Position Accuracy
Atlas Basic – 50 cm 95% (30 cm RMS)
Atlas H30 – 30 cm 95% (15 cm RMS)
Atlas H10 – 8 cm 95% (4 cm RMS)
