Dual antenna heading solution

Farm implement in a field

Heading for static and slow-moving machines

Get the important heading information your robots need to be successful in the field with NovAtel’s dual antenna solutions.

This dual antenna solution provides a high-accuracy position with a heading, even when the machine is stationary or operating at slow speeds. 

By starting with reliable equipment, you can customise and grow your GNSS solution to suit your evolving needs without having to replace your positioning equipment. With the dual antenna solution, you get the heading information you need with an integraste IMU, reducing the need for additional sensors. 

Dual antenna solution includes: 

  • SMART7-SI 
  • SMART2 
  • ALIGN firmware 
Standard Hardware Features Benefit
SMART7-SI
  • Integrated IMU
 Allows for a terrain compensated position, and high accuracy roll and pitch of the vehicle. Includes access to raw IMU data.
  • Multiple input/output
 Flexible for your system’s needs.
  • ROS integration
 Speeds up system integration.
  • PTP timing
 Provides improved sensor performance and logging accuracy. Eliminates the need for additional hardware on the robot.
  • Ethernet and Wi-Fi connectivity
 Provides flexibility for remote connectivity and monitoring.
  • SPAN technology
 Keeps the machine uptime as high as possible through minor GNSS outages. It is especially useful for tree line and orchard activities. Provides the ability to move the reference point to another point of the vehicle saving integration time, increasing accuracy and removing the need to translate the position output.
SMART2
  • Provides stand-alone positioning and static and slow-moving heading
 Provides machine with vital position and orientation information to mitigate operator involvement.
  • ALIGN rover for heading
 High accuracy heading computed relative to the SMART7-SI. Provides heading, even when the machine is stationary.
  • Dual-frequency with flexibility to enable access to all constellations
 Increased signal availability and redundancy.
