APPLICATION / MARINE SYSTEMS

Measure movement.
Transfer to the system.

From acoustic imaging and fisheries to marine robotic navigation. MARO instruments provide measurement data to systems that need to take into account the orientation and movement of the vessel.

02 / SONAR · MRU

Hydrography and fisheries

The movement of the vessel changes the orientation of the acoustic equipment. Sensor data allows you to take into account motion when processing sonar and multibeam echo sounder measurements. A separate version is provided for fishing equipment MS-21F.

Sonars and multibeam echo sounders
Data for heave compensation systems for underwater acoustic measurements.
Fishing equipment · MS-21F
Measuring roll, pitch and azimuth for motion compensation in fishing sonars and echo sounders. In the material MS-21F linear acceleration and angular velocity transmission, serial interfaces, and Ethernet are also described.
03 / DP

Dynamic positioning

Dynamic positioning systems need data about the ship's movement. The MS series sensor serves as a source of measurements for the on-board DP complex.

Sensor included in DP
Transfer of motion measurements to the on-board dynamic positioning complex. Position holding algorithms are implemented by the DP system itself.
04 / HMS

Strength and stability

Data on angular and linear motion are fed into automatic monitoring systems for hull strength and current stability of the vessel.

Hull monitoring HMS
Data on the dynamic movements of the vessel for the strength and stability control system. The sensor supplies the measurements; The condition assessment is performed by the monitoring system.
05 / MONITORING · AHS

Helipads

Monitoring the movement of the helipad and actively compensating for its roll solve different problems. For each of them, the sensor transmits measurements to the corresponding ship system.

Helipad monitoring
Measurement data for monitoring the movement of the platform on a ship.
Active compensation AHS
Sensor as part of the helipad active roll compensation system.
06 / ORIENTATION

Ship antennas

Changes in the ship's orientation must be taken into account when pointing the onboard antennas. The sensor transmits measurement data to the antenna orientation system.

Antenna orientation
Transfer of orientation data to the antenna control system. Actuators and pointing algorithms belong to the antenna system itself.

CARRIERS / ABOVE AND UNDER WATER

From a research vessel
to an underwater robot.

Surface vessels and underwater vehicles, transport fleet and special-purpose vessels. For fish-finding equipment there is a design MS-21F.

MEASUREMENTS / DATA COMPOSITION

What does the on-board system need?

The composition of measurements is selected according to the task and performance of the device. The MARO catalog distinguishes between inertial units IMU, motion sensors MRU, orientation systems and GNSS / INS versions.
