THE SYSTEM IN PRACTICE
How it fits
your work.
The Omnitrack surface module integrates two GNSS receivers to determine position and heading. This approach reduces reliance on magnetic heading measurements.
The system can integrate with BlueROV and optionally Tracker 650 DVL. Data fusion requires correct ArduSub configuration. For standalone use, data can be displayed in Cerulean SonarView.
USBL and DVL integration
Complementary information for estimating ROV position.
Wired or wireless
Two connection options for the surface module.
CONFIGURATIONS, EQUIPMENT AND DATA
A closer look.
Surface buoy and position estimation
The ring-shaped surface module can be transported by car. Two GNSS receivers provide position and heading, reducing reliance on magnetic measurements. The system integrates with BlueROV and optionally Tracker 650.
ArduSub can fuse acoustic USBL and DVL measurements when correctly configured. For use independently of BlueROV, SonarView collects and displays the data.
Wired and wireless configurations
The wired configuration uses 25 m of neutrally buoyant cable for power and communication. The wireless configuration uses a lithium-ion battery in an IP65 enclosure: the surface enclosure’s protection rating is not the acoustic unit’s diving depth.
Specifications for the earlier Mk III configuration
These values apply to the Mk III configuration, not the Mk V kit. Resolution does not equal absolute positional accuracy; the 300 m depth exposure applies to the specified acoustic unit, not the entire surface module.
| Maximum depth exposure (minimum crush depth) | 300 m |
|---|---|
| Maximum Range | 300 m |
| Apparent yaw (azimuth resolution) | 0,1° |
| Apparent elevation angle resolution | 0,1° |
| Slant range measurement resolution | 0.1 m |
| Update Rate | 1Hz |
| Ping Frequency | 25 kHz |
