Description
Product details:
The blue MRUs models (serial number 19000 and below) are all now obsolete and have been replaced by the following fifth generation MRUs:
•MRU 5v
•MRU Hv
•MRU 3v(replaces MRU Z)
•MRU 2v
•MRU Dv
• mru
By its very nature, operating a ship at sea is a challenging activity. To undertake tasks such as wave height monitoring, using cranes in bad weather, or determining where a ship is using dynamic positioning, it is necessary to measure roll, pitch, yaw, and heave motion. This is where the Motion Reference Unit (MRUs) comes in, and KONGSBERG has been leading the field for 25 years.
The MRUs are suitable for any offshore operation requiring attitude determination and motion compensation. Kongsberg’s motion sensor family provides high precision motion measurement in all dynamic environments. They cover all Marine activities from small hydrographic vessels to large vessels and facilities.
Typical application
Motion compensation of single – beam and multi – beam echo sounder
Azimuth and attitude measurement of underwater vehicles and remotely operated vehicles
Motion control and damping system for high speed ships
Heave compensation of Marine crane
Dynamic positioning
Underwater acoustic location
Ship motion monitoring
Sea wave measurement
Antenna motion compensation and stabilization
RMP201-8 8 x Multi-purpose (digital/analog/power meter) Input/output 2 Serial Line interface module RSER200-4 4 x RS232/RS422/RS485 input/output 1 Power unit QUINT/PS/1AC/24DC/10 100-240V AC input /24 VDC, 10A output The preceding devices are installed indoors in a protected environment.
Remote input devices enable users who are far away from the computer to perform batch input jobs on distant computers. The simplest structure of the device consists of a printer, a card reader and its communication-control processor. Since the information in the communication line is transmitted in serial mode, the communication control processor in the equipment needs to convert the information input to the computer from parallel to serial and send it to the communication line, and then output the information sent from the communication line from serial to parallel. In addition, information transmission and error correction should be monitored according to the specified communication procedures.
High reliability
Kongsberg’s MRUs use a solid state gyroscope and accelerometer to provide real-time motion measurement with high dynamic accuracy. State-of-the-art design, construction and assembly inside the MRUs provide extremely high reliability in the most demanding Marine environments.
The integration of technical art and application
There have been many different versions of microelectromechanical systems (MEMS) based gyroscopes over the past 25 years, and the constant focus on innovation and ingenuity has resulted in ever-increasing cost performance. As a result, today’s MEMs-based gyroscopes challenge “easy wear” mechanical gyroscopes as well as those based on fiber optic (FOG) technology. Optimized for high-end applications in the KONGSBERG Motion Reference Unit(MRU) product family, the KONGSBERG gyroscope is a good example of MEMs-based gyroscope design, demonstrating a new level of performance for the technology.
