Calculations are done on an ellipsoid of choice (default WGS84).
Based upon Vincentie's formula.
Results are given in meters or Nautical Miles (NM.)
Calculations are done on WGS84.
Based upon Vincenty's formula.
Will allow the user to fix times at certain Way-points and shows a warning when time(s) cannot be realized.
Shows a Where Should I Be position, a Speed To Go and Course To Go.
Man Over Board and GoTo functionality.
Breaks up GC. tracks longer than a given distance into loxodrome parts.
Closest Point of Approach, will calculate the CPA of two tracks, given Course, Speed and initial positions
Allows the user to transform Lat/Lon/Altitude from a given datum to another.
Shows the tidal information of 1 or 2 harbours.
This program uses the BATT method.
Users can add additional harbors using data from the BATT tables.
Calculates the intersection of two Great Circles.
Graphical/Textual display of LOS for up to 5 sensors (e.g. Radar), given the height of the sensor.
Graphical display of available stars given approximate position and time.
Up to 10 stars can be selected for observation.
Graphical display of all LOPs and a confidence ellipse.
User can disable stars which seem to be in error and recalculate the fix.
All relevant statistics are shown.
There is a choice of two catalogues, Navigational stars and Bright stars.
Sun, Moon and planets are visual on all displays, but cannot be used for a fix (for now!).
Given Time, Altitude and Azimuth the program will calculate a position using only one star.
It will find a star automatically, given the Time, Altitude and Azimuth of observation.
Should be a useful tool for checking e.g. the accuracy of the Mirador.
Simple DR program.
Graphical display of Sun- and Moon position.
Real Time display.
The phase of the moon and twilight's are also displayed.
Internet connection required.
This program will grab the data from a RWS server and display historical, predicted and astronomical values for a given port
Purpose: check the accuracy of a GPS receiver using NMEA messages.
Given a log file of NMEA data (static observations) the program will calculate all relevant statistics of the data set.
A list of missing/wrong records will be shown.
Calculates from 2 speeds/headings (SOG, STW and Current) the third one.
