The JRC office situated in the Netherlands serves as the European and African main center. Today, we have over 25 authorized and JRC preferred distributors. Contact information for our partner in your country can be found via the network pages.
The quickest and easiest way is to contact us who will advise you on how to get JRC onboard.
Contact your local JRC service agent for details of the JRC service agent in the country you require service.
Retrofit: Please contact the JRC distributor who originally sold you the equipment. Provide them with the model and serial number of the equipment, after confirming the warranty status with JRC Europe. They will guide you through the warranty process and will be your point of contact throughout you claim.
Newbuilding: Have you send warranty claim to the shipyard and have you received warranty confirmation?
Operation manuals can be requested from your local JRC dealer, manuals for more recent models can be provided in PDF format. For older equipments please contact your local dealer who will advise you of availability.
The second generation and patented Constaview™ is realized through the use of three high-speed processors (in-house Tornado™ technology). All information gathered by the radar is fully processed within a few milliseconds before being displayed.
A smooth image rotation is generated when sailing in Head-up mode. When changing to North-up, the new radar image is displayed without any delay caused by the scanner rotation
Developed exclusively by JRC, TEF™, allows target enhancement relative to the target size. The smaller echoes are far more enlarged than bigger echoes, giving a better on-screen separation and identification.
JRC's new IMO approved JMA-9172-SA, S-band Solid State radar, represents a new generation of marine radars, utilizing advanced signal processing technology to display targets with high accuracy while using a stabilized high-power solid state transceiver. The advanced radar functions and operation are based on JRC's successful JMA-9100 radar series.
The marine radars are available in X-band and S-band frequencies. X-band operates at a frequency of approximately 9.4 GHz, while S-band operates at approximately 3 GHz. X-band offers greater resolution and detection of smaller targets, but is subject to interference from rain and seas. S-band radar has a longer range and less interference from rain and sea clutter, but has less sensitivity for small targets.
A ship will typically use her X-band unit near shore, due to its higher resolution and ability to detect smaller targets, but depend on S-band while at the “open seas”. It is recommended for large oceangoing vessels to install both X-band and S-band radars.
Typically, a cylindrically shaped array, horizontally fixed to a turning unit which for marine applications will rotate 360°. Radar scanners come in many configurations depending on the size, speed and areas in which the vessels sails. For example, the speed of rotation for vessels travelling at less than 30 knots would be 24-28 rotation per minute (rpm). For high-speed vessels, the rotation speed is doubled to 48 rpm. The physical size of the array unit can vary from 2 ft for leisure craft to 12 ft in respect of S-band radars fitted on large deep sea vessels.
The International Maritime Organization (IMO) is a specialized agency of the United Nations which is responsible for measures to improve the safety and security of international shipping and to prevent marine pollution from ships. The ownership and management of chain surrounding any ship can embrace many countries and ships spend their economic life moving between different jurisdictions, often far from the country of registry. There is, therefore, a need for international standards to regulate shipping - which can be adopted and accepted by all. The first maritime treaties date back to the 19th century. Later, the Titanic disaster of 1912 spawned the first international safety of life at sea - SOLAS - convention, still the most important treaty addressing the maritime safety.
As times change and new technologies are introduced at an ever increasing pace, maritime communication and navigation equipment have also become more sophisticated. Monitoring all of this equipment causes a greater burden on the crew. JRCs' Remote Maintenance System (RMS) has the ability to cost-effectively monitor performance and functionality of onboard equipment while at sea, significantly reducing downtime and maintenance costs.

At JRC we are continually looking for ways to enhance our service capabilities and the introduction of the worldwide First Aid Kit system allows us to do this as quickly and efficiently as possible.
These First Aid Kit’s are strategically located at JRC offices and those of our support partners, stationed close to or at, the world’s busiest ports, and countries closely connected to areas of greater maritime activity, optimizing flexibility and availability.
A single First Aid Kit comprises a wide range of essential parts, significantly aiding prompt response and service of equipment within a minimum timeframe. JRC can provide urgently requested parts, thus maximizing quick and cost-effective repair with minimum downtime.
In addition to web based solutions, JRC operates a conventional telephone 24 hours a day, 7 days a week system called the JRC one-call™. This is always available via the Tokyo, Amsterdam & Seattle offices.
JRC one-call™ also known as the ‘follow-the-sun service’, is always available to our customers ensuring your call has our immediate attention for any requested support. Provision of ‘always available’ service, in conjunction with our trilateral platform, has proven substantial benefits to our customers.
Global warming has pushed environmental conservation into the main stream. Environmental protection is important for the conservation of precious natural resources and the continued health of our planet. JRC recognizes its responsibility as a global citizen and is continually striving to reduce environmental impacts.
At JRC we design our products to be efficient both mechanically and electrically. Energy consumption is one of the most significant environmental impacts an electronic device produces over time. One of JRC's key goals is to create energy efficient products. Learn more.
