GPScalc SH3 Publisher's Description

GPScalc is a calculator to convert between geodetic longitude and latitude to UTM eastings and northings and to calculate distance and headings between waypoints with great accuracy.

GPScalc allows you to calculate distances to within 1 cm accuracy between your GPS position fixes. This is based on the condition that start and end points fall within the same UTM zone and the distance between points is less than 1000m. Otherwise, for greater distances it can still calculate within 0.5% accuracy.

Features of GPScalc :

  • Input style can be ddd.dddddddddd, ddmm.mmmmmmmm or ddmmss.ssssss
  • Output results can be Metric (meters), statute (miles), or nautical (sea miles)
  • Built in database to save and recall waypoints
  • Supports about 38 user selectable ellipsoids to use in conversions
  • Converts Lat/Long to UTM or UTM to Lat/Long
  • Resolution is 1 mm and accuracy is better than 1 cm.
  • Convert with between degrees, minutes and seconds formats (dd.dd/dd mm.ss/dd mm ss.ss)
  • User can choose between three different Heading/Distance measurement methods. These are:
    • Geodetic Method - Results are equivalent to those calculated by the U.S. National Geodetic Survey reference programs.
    • Haversine Method - Results are equivalent to those given by GPS devices with built in Heading/Distance functions.
    • Rhumb line Method - Results are equalvalent to those often used in aeronautical and maritime navigation.

Navigational Calculations

  • If you know the coordinates of two points you can calculate the bearing and distance between the two.
  • If you know the coordinates of one point, as well the bearing and distance to a second unknown point, then you can calculate the coordinates of the second point.
  • If you know the coordinates of two points, and the bearing from each to a third unknown point, then you can calculate the coordinates to the third point.

GPScalc also has the following features:

  • It automatically remembers the last coordinates you entered. This allows you to switch to another application (for example the calculator) and return right back to where you were before.
  • It has a built in converted to convert between ddd.dddddd, ddsmm.mm or dddmm.ss formats. This means you can enter data exactly as its displayed on your GPS for more convenience.
  • It allows you to save an recall waypoints. This makes it far more convenient than having to enter the coordinates each time manually.
