Overview
MRT is supplied as part of our Micro-Ranger 2 USBL system, a complete one-box underwater diver, ROV, AUV and equipment tracking solution. Everything you need, including two transponders, is supplied in a battery-powered IP-67 rated carry case for portable, go-anywhere marine operations.
MRT is supplied with a moulded 10 m underwater cable that is connected up to your Micro-Ranger 2 command case. The cable provides both power and comms to the MRT.
At a glance
- Easy to deploy off a pontoon or RHIB
- Optimised for high elevation tracking in shallow water
- Internal magnetic compass for instantaneous and calibration free motion compensation
- Built in health checks including array and electronics diagnostics
- Supplied with 10 m of deck cable
Deployment is as simple as it gets. Off a pontoon, over the side of your RHIB or even fixed to a USV. It can be suspended using its cable or on a simple pole arrangement. We even offer a lightweight carbon fibre pole with fixation clamp and a top bracket to mount the system’s included GNSS antenna.
MRT uses an integral AHRS sensor which provides pitch, roll and heading data that automatically compensates for the dynamic motion of the vessel, removing the need for an external sensor and pre-use calibration. It’s multi-element processing enables transponders to be accurately positioned at ranges of 995 metres.
