Description:
Navigate is a Palm OS program for computing the range and bearing between any two points on the Earth's surface OR the end location given a starting location, range and bearing.

It will compute these solutions for either lines of constant bearing (loxodromes or rhumb lines) or the shortest possible path on the Earth (geodesics or great circle routes).

The calculator also supports the conversion of angular units between decimal degrees, degree and decimal minutes, or degrees, minutes and decimal seconds; and range units of kilometers, nautical miles, statue miles, meters or yards.

The complete source code is also available on the author's web site.

Description:
Earth&Sun Color is a color version of Earth&Sun.
It runs on color handhelds with Palm OS v3.5 and greater.

For monochrome handhelds use Earth&Sun available on this website.

The Earth&Sun program shows the Sun Illuminated area of the Earth with 1X, 2X and 4X maps of the earth.

It also displays:
- The latitude and longitude of an Earth location.
- The time zone at that location, based on only longitude not civil boundaries.
- The current time at that location based on the above time zone.
- The sunrise and sunset times, and day length at that location.
- Distance between two locations on the earth surface.

Earth&Sun can also be a real time clock on the handhelds which can run in their charging cradle.

It allows the Reference Information to be imported from the GeoDB geographic database, and it accepts 1/2 hour time offsets from Greenwich.
