Plotter and charting.
The plotter uses up to 100 different images (supplied by the
user) merging them in order to display a single chart where
the vessel is displayed and moves at real time.
Display of objects in database (see below), position of mouse
cursor, distance and bearing from the vessel, track made good
and way point list tracking.
Use of mouse to measure directions and distances, plot bearings,
fill a waypoint list or position the vessel at a desired location.
Zoom from 0.25 to 9 000 nautical miles. A right mouse-click
enables the user to select a section on the plotter, which can
be enlarged by using the zoom-functionality.
World wide planning chart, for a zooming-range of more than
250 nautical miles.
World wide shorelines database, which can be displayed with
a zooming-range between 0.25 and 250 nautical miles.
Scanned Mercator Projection charts. Scan your own charts!
Fill your own object database (light houses, ports, mountains,
Import and export capabilities to exchange scanned charts
and objects with other users.
Nav_Data window with navigational numeric data updated every
second: local and GMT date and time, estimated or GPS position,
compass and true course, ground and over water speed, bearing
and distance to next way point, etc. One single button starts
the Man Overboard procedure which opens a window showing the
man and the vessel, distance, bearing and elapsed time.
Dead reckoning and piloting
If a GPS is not connected, navigation is done by dead reckoning,
and in addition, by using leeway and current data maintained
in the logbook. Fixes can be done by analysing the amount
of saved miles by using bearings to different targets, by
analysing bearings at different moments to the same target,
by processing the distance from high objects beyond the horizon,
by analysing celestial sights or meridian transit, or by copying
the position from an unconnected GPS to the logbook.
Fix with 2 to 4 sights or upper meridian transit. Latitude
with Polaris is supported as well. The nautical almanac is
automatically kept up to date by EASYNAV. Calculated data
can be overwritten with the one stored in other almanacs,
if based on the users requirements.
A bodies finder gives GHA or SHA, declination, parallax and
semi-diameter of bodies at any time as well as altitude, azimuth,
GHA Aries and Moon phases. It also allows the user to print
his own Nautical Almanac for the desired period.
Create as many WPL as required, each with up to 499 way points.
The user may switch to the desired WPL during navigation at
Create a Great Circle route divided into the desired number
of way points entering departure and destination only. Select
your GOTO way point: the plotter will give you date and time
of arrival and VMG to it.
A WPL may be filled manually, by using objects stored in the
data base or by clicking on the mouse-button on the plotter.
You enter tidal data for low, high and next low tide for principal
and subsidiary ports to obtain a grid with a row for each
5 minutes of tidal time with height of water, speed of current
and course to steer and speed over ground.
Moon phases may be determined by using the EAYSNAV Nautical
Any GPS (or other navigation system) with NMEA 0183 output
capabilities may be connected through a serial (COM) or USB port.
When GPS is active, EASYNAV stops reading data from the logbook
used to calculate the estimated position, using GPS latitude
and longitude data. Ground track and speed are then calculated
by using successive GPS positions. If GPS fails, last position,
speed and course are written to the logbook and the system
continues navigating using the EASYNAV calculation.
A GPS Reader is also supplied to monitor GPS output data in
order to solve problems if any issues should occur.
A 5 languages dictionary is supplied with over 500 terms.
The user may edit the dictionary to modify or add terms to
it. An empty column allows the maintenance of terms in a sixth
