In marine mapping applications, the up and down movement of a ship or boat may lead to errors in depth measurement. Using receivers with the Synchronous Position, Attitude and Navigation (SPAN) technology that features a strong heave option can reduce these errors. The NovAtel SPAN Heave firmware offsets the vertical movement of the vessel and produces a more accurate positioning solution.
The SPAN technology integrates the inertial navigation technology and the GNSS (Global Navigation Satellite System) technology to provide a stable and accurate three-dimensional navigation solution that delivers complete orientation and attitude.
NovAtel offers two SPAN Heave solutions.
- SPAN technology to provide continuous 3D navigation solution
- Heave output option to offset vertical movement of vessel
- Multiple IMU options available
- Well suited for marine applications
- Two options available
With the real-time measurement solution, SPAN enabled receivers deliver real-time and precise measurement of wave motion. There is a 6 degree-of-freedom orientation and position, measuring velocity, position and attitude.
NovAtel’s Waypoint Inertial Explorer post-processing software processes the data backward and forward to make sure that the results are precise and reliable.
