SPAN® Land Vehicle

NovAtel’s intelligent vehicle dynamics modeling and our patented Antenna Phase Windup technology come together in NovAtel’s SPAN Land Vehicle firmware to provide accurate position, velocity and attitude. 

Features

  • Continuous position, velocity and attitude output through extended GNSS outage
  • Enhanced navigation performance in low dynamic applications
  • SPAN intelligent vehicle dynamics modeling
  • Patented Antenna Phase Windup technology
  • Available for all SPAN supported IMUs

The below table depicts the average SPAN Land Vehicle performance at 1 hour of complete GNSS outage during typical driving conditions at an average speed of 65 km/hr. Position errors are represented in percent Error Over Distance Traveled (EDT).
