NovAtel’s STEADYLINE® is a GNSS receiver firmware technology designed to reduce position jumps that occur when transitioning between different positioning modes. This is especially critical in precision steering applications such as agricultural and machine guidance systems, where sudden shifts in position data can disrupt operations. STEADYLINE ensures smooth transitions between high-accuracy RTK and lower-accuracy modes like PPP (TerraStar), DGPS, SBAS+GLIDE, or autonomous GLIDE™.

Features

• Multi-Mode Compatibility: Works seamlessly with RTK, PPP, DGPS, SBAS+GLIDE, and autonomous solutions.
• Four Accuracy Models:
  • Maintain: Applies a fixed position offset during mode transitions to prevent jumps.
  • Transition: Gradually shifts to the new reference position over a user-defined time.
  • Prefer Accuracy: Chooses transition behavior based on accuracy level changes.
  • User Accuracy Levels (UAL): Allows users to define operational, warning, and out-of-bounds thresholds.
• Accuracy-Based Reporting: Adjusts solution type in GPGGA and BESTPOS messages based on current estimated accuracy.
• Automatic Mode Switching: Internally monitors position offsets and switches to the next best available mode when needed.

Benefits

• Smooth Positioning: Minimizes disruptions caused by sudden GNSS mode changes.
• Enhanced Steering Performance: Ideal for precision agriculture and autonomous machine guidance.
• Customizable Accuracy Thresholds: Users can define operational limits to control behavior and reporting.
• Reliable Transitions: Maintains continuity even when high-accuracy corrections are lost.
• Fail-Safe Behavior: Automatically disables STEADYLINE if position exceeds warning limits, ensuring system integrity.
