Apogee-A High Accuracy Motion Sensor

Apogee-A: High Accuracy Motion Sensor

Manufacturer: | Categories: ,

The Apogee-A: High Accuracy Motion Sensor from SBG Systems is the latest addition to Canal Geomatics motion sensor collection. This motion sensor provides the best motion reference unit (MRU) in the industry, which encompasses exact real-time heave that is accurate up to 5 cm.



The Apogee-A from SBG Systems offers an affordable and precise motion sensor system by utilizing IMU calibration, testing and filtering for one of the highest precision MRU systems that is accessible for any surveying company. For added easiness, there is no need to input the wave frequency since this system detects it automatically and corrects itself as needed.

The Apogee-A includes an exclusive delayed heave piece that doesn’t require any additional software. This particular algorithm permits a more detailed calculation, resulting in a heave accuracy up to 5 cm, which is shown in real-time with a minimum delay.


  • Precise multi-beam sonar motion compensation
  • Postponed heave for problematic sea conditions
  • Unbroken post-processing workflow
  • Internal 8 GB data recorder
