Unique features

The JAN-701B is a newly developed multi-functional ECDIS.
It is ergonomically designed to enhance the working
environment and man/machine interfaces, providing
continuous position and navigational safety information.

Radar overlay

The JRC JAN-701B o ers practical radar usage with ECDIS,
more than just overlaying a rough radar image. The radar
image has a high resolution when interfaced with JRC radars.
The radar image does not hide the priority objects of vector
charts, but overlays them on the radar image. At the same
time, brilliance and clutter controls of the radar images
continues to be operable.

AIS targets

The AIS is an important key device used to indicate AIS target symbol and information
on the ECDIS. These targets are very useful, as it provides the maneuvering conditions
of other ships at a glance, allowing for safe and e ective navigation. The name of

the vessels, and bearing, range, speed,
length, heading and much more AIS target
speci cs from other ships are received and
displayed. The AIS symbols are continuously
displayed on-screen without the in uence
of the radar characteristics. The AIS targets
are never shielded by ground, rain or cloud
re ections, nor are they eliminated by
adjustments of anti-sea or anti-rain clutter.

Also, it is easy to activate, deactivate
and switch between AIS target
symbols. This simply can be done
with an integrated AIS  lter,
prioritising the targets within a
dedicated area.

Multi-view

Multiple and wide screen viewing is possible with the new
JAN-701B. You can divide the chart screen into two sections,
in which the same or di erent charts can be displayed, in a
mixture of ways. In this  eld of view, it provides a ‘look-ahead’
capability, especially useful in coastal areas. With the wide
screen view function, an additional screen in the display area,
showing a segment of the chart, allows viewing at a glance.

Flexible black box configuration

The ECDIS system is available in stand alone and desktop versions to suit
your type of vessel. In the desktop version, the processor unit is the heart of
the JAN-701B, allowing for  exible installation approach in con ned spaces.

User interface

With its simpli ed menu structure, the new JAN-701B shares the same insightful user
interface as found in JRC’s new radar series. The consistent visual appeal and intuitive
usage is of great importance on the vessels bridge, especially being a working and living
environment for thousands of vessels’ o cers on a day to day base.

Conning and external sensors

You can easily connect a wide range of navigation equipment
to acquire more information. The ECDIS will display exactly the
info you need in a clear, uncluttered format, reducing the risk of
accidents. This results in a more relaxing and secure operation. Even
equipment from di erent manufacturers can be incorporated.

RADAR

ECDIS

More powerful than ever

The JAN-701B incorporates two Tornado™ processors, which are exclusively developed and designed by JRC,
bringing a new level of performance and reliability to ECDIS operation. The new Tornado™ processors, which
equal the power of eight conventional processors, allow radar overlay processing within a few milliseconds
before displayed. This generates a smooth and fast image update. The advanced system architecture, make
the JAN-701B series probably the most sophisticated ECDIS available today.

CCRP

As set by IMO regulations, a Consistent Common Reference
Point (CCRP) is a location on own ship, to which all horizontal
measurements, such as target range, bearing, relative course/
speed, closest point of approach, or time to closest point of
approach are referenced.

Where multiple antennas are installed, di erent position o sets for each antenna in the radar system
should be applied with respect to the CCRP. If you switch between scanners (up to 8 possible - option),
the information displayed is generated, which allow for consistency and uniform output.

Man OverBoard

Some items could strike you on the vessel, a slippery deck or
unexpected movement of the vessel are situations in which a person
may possibly fall of the vessel. The JAN-701B integrates a single-press
Man OverBoard (MOB) operation. Instantly, a dedicated symbol arises on
the screen, providing a range detailed info such as positioning, bearing,
range and time till arriving at MOB. This emergency system enables
immediate and accurate search and rescue e orts.
