EASYNAV enables navigation with or without GPS. Without GPS, EASYNAV navigates by processing the data the user enters in the logbook, including compass and mile register errors, leeway and stream.

Among others, EASYNAV includes the following features: piloting, dead reckoning, celestial navigation and GPS lecture as well as other programs used to calculate and correct course, rhomb lines and great circle tracks, tide calculator with course correction for currents every 5 minutes of tidal time and a powerful program for waypoint lists compilation. It also supports the user in determining the arrival point after a passage.

• Vessel configuration allows you to record general craft data as well as data used to automatically propose
• corrections to navigation data, as mile register correction factor, and steering and bearing compasses deviation tables.
• Objects for navigation. Create your own scenario by configuring objects such as light houses, ports, radio beacons, capes, mountain tops, etc. Objects are used by EASYNAV on many occasions for plotting bearing, compiling way point lists, calculation of distance and tracks and so on.
• Worldwide shorelines data base to draw planning charts all over the world.
• Chart imaging. EASYNAV can use image files taken from Mercator projection charts, obtained for example by scanning nautical charts. It is irrelevant if charts are on different scales, the EASYNAV plotter knows how to zoom in and out. EASYNAV will then be able to display simultaneously up to 100 mixed charts by generating one single image.

As the vessel moves, on a one second interval a panel next to the plotter shows up navigational data. This panel indicates local and GMT time, calculated or GPS position, compass and ground heading, miles saved, speed over the water and ground, distance, true and magnetic bearing, time of arrival and VMG to next way point. On this panel the user has the possibility to change the setting of the plotter’s zoom in a range of 0.25 to 9000 nautical miles.

By using the mouse you can easily display:

• The number of miles, the true or the magnetic bearing between the vessel and the mouse pointer.
• Magnetic variation. The values mentioned in above section are always indicated on a status bar and updated continuously.
• Press the left button and drag it to measure miles and to show true or magnetic bearing between any locations on the plotter.
• Open an enlarged window by pressing and dragging the right mouse-button.
• Position the vessel in any location with a click.
• Click two targets where bearings have been taken to, and obtain immediately the fix.
• Click a target where a bearing and sextant altitude have been taken to, and immediately obtain the fix. Two different bearings to a single target can be calculated and indicated.
• Click on different locations in order to create the waypoint list.

Enjoy the thrill of celestial navigation: let EASYNAV calculate data for celestial bodies. The user can even print his own Nautical Almanac. For sights, time and sextant data can be entered. Latitude with Polaris and upper meridian transit of any celestial body are also included.

The user also can connect his GPS (or any other navigational equipment) with standard NMEA 0183 output interface to a serial or USB port in his computer. EASYNAV reads the sentences as GLL, RMA, RMC, GNS or GGA using longitude and latitude for navigation. If the GPS system encounters a technical problem, EASYNAV automatically enters the last position, course and speed into the logbook and navigation continues by calculation.

Minimum requirements:
Compatible PC with:
Windows 2000 / XP
CPU 300 Mhz
RAM 32 MB
Free HD 105 MB. Space required increases when implementing data bases and images.
VGA 800 x 600 16 colours screen
Mouse

To combine this product with GPS, a free serial (COM) or USB port is required.
A page graphic printer is needed in order to allow printing.

Restrictions and warnings:
Width of charts as well as lines and distances between way points must have a difference in longitude which lies under 180 degrees between east-most and west-most ends. Distances are always measured through the shortest side.

Since only Mercator projection is used, the plotter does not display latitudes over 85 degrees. EASYNAV is not to be used for polar navigation. Worldwide charts and objects supplied by EASYNAV are examples and are to be used as reference and examples only.

Shorelines may differ more than 0.5 nautical miles from WGS84.

When using this software for navigation, paper charts, pilots and all needed documentation must be onboard.

For the Tides Calculator, the tidal data is to be supplied by the user. WxTide32, the freeware software for tide prediction by Michael Hopper is included in the EASYNAV package.
Neither the author, nor anyone else but the user is responsible for any event or damage occurring to people or property while using EASYNAV or data produced by EASYNAV.

NMEA 0183
The NMEA (National Maritime Electronic Association) standard 0183 for Interfacing Marine Electronics Devices is a voluntary industry standard. It calls for data communication in form of coded “sentences” between electronics appearing on boats. It defines electrical signal requirements, data transmission protocol, timing and specific sentence formats, with huge advantages for customers.

When buying a GPS, we recommend to verify that a NMEA 0183 standard output is supplied.

Nautical Almanac:
The Nautical Almanac is a yearly publication which provides celestial body positions and tables to correct altitude data.

Navigators use this data to obtain, among other things, the position of the vessel.

EASYNAV calculates its own almanac with sufficient accuracy for a time frame that includes years from 1950 to 2050.
