midpoint bearing
GPS Point2Point Calculator 1.0
GPS Point2Point Calculator allows you to calculate distance and bearing between two GPS coordinates. more>>
You can choose to display distance in meters, kilometers, feet, miles or nautical miles.
Furthermore you can select if calculations should be based on True Bearing or Rhumb Line Bearing.
System requirements:
- Palm III
- Palm OS v3.0
Navigate 1.4
Navigate is a Palm OS program for computing the range and bearing between any two points on the Earths surface OR the end location given a starting location, range and bearing. more>>
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 authors web site.
SunAngle 0.8
SunAngle is a program showing data about the Suns rise time, set time, and its current bearing. more>>
SunAngle 0.8 is a program showing data about the Sun's rise time, set time, and its current bearing. By pointing your Palm Pilot at the Sun, this program will tell you which way North is. In addition, it draws pie slices on the compass face showing where the Sun will rise and set that day, during the summer solstice and winter solstice. This could be useful for architects, real estate agents, home buyers (does this balcony get any sun in the winter?), and solar installers.
Alti Calc by Mark 2.0.0
Alti Calc by Mark is a program for calculating the altitude of a model rocket from tracking station measurements. more>>
Alti Calc supports single and dual tracking station systems.
Dual station tracking data can be reduced using either the vertical midpoint calculation method or the geodesic calculation method.
Cronodrive 1.0.1
CronoDrive is a small J2ME application -a midlet- designed to help you to reduce the time spent driving usual routes, like from home to work and back home. more>>
System requirements:
- Java compatible
Ephemeris 1.0
Ephemeris is a program that lets you enter a date and a location and then computes the time and azimuth (compass bearing) or sunrise, sunset, moonrise and moonset. In addition, it displays a schematic more>>
It can also generate a table listing the positions of the sun and moon in the sky and the length of shadows cast by the sun at 15 minute intervals for a given day.
In Calendar mode, it can display the phases of the moon for any given month.
Finally there is Compass mode -- just point your pocket PC at the sun or moon and it tells you which way is north.
GreatCircle 2.0 Build 404
GreatCircle is an application for Palm OS based handhelds to compute the greatcircle distance and bearing angle between two locations on the Earth. more>>
GreatCircle is used in conjunction with the GeoDB database application.
GreatCircle is the computation engine and GeoDB holds the location database.
TheGreatCircle archive (gc12.zip) includes GeoDB in case you do not have GeoDBinstalled in your handheld.
Enhancements:
- Major update. More accuracy, units and decimal digits

CopanMobile for Palm 1.0.3
Free coordinate geometry (COGO) tool for field surveyors and map drafters. more>> CopanMobile for Palm is a very efficient and easy-to-use geomatics engineering tool for computing and managing plane survey coordinates. It does numerous coordinate geometry (COGO) calculations, processes and adjusts raw field survey data, computes and adjusts map traverse data, performs map checks, calculates curves, areas and perimeters, performs coordinate transformations, imports/exports Ascii files, and has GPS positioning and navigation functions.
It supports quadrant bearings as well as azimuths, and gons (grads) as well as degrees. Its coordinate files may be copied to the Palms memory card or to a removeable memory card and used directly by the Windows version of Copan.
Designed for land surveyors, geomatics engineers, professionals and students, CopanMobile for Palm is available for download, free of charge. A valid email address is required for a password and for news of updates.<<less
GPilotS 6.2
GPilotS is a simple to use, yet sophisticated utility which allows your PalmPilot to talk to your Garmin GPS to send and receive waypoints, more>>
GPilotS 6.2 is a simple to use, yet sophisticated utility which allows your PalmPilot to talk to your Garmin GPS to send and receive waypoints, routes and tracks talk to map softwares to exchange waypoints, routes and tracks with them create and edit waypoints and routes converts formats of waypoints, routes and tracks dynamically.
Major Features:
- Waypoint creation/edition : you can create new waypoints with their lat/lon, distance/bearing from a reference point and modify name, coordinates, comments, symbol, display attributes,...
- Display symbols support : GPilotS supports the waypoint symbols of the Garmin GPS 12, 48, II+
- Datum conversion : you may select among 100+ datums to display or enter waypoints coordinates
- Storage : waypoints, routes and tracks are stored efficiently in three databases and displayed sorted by categories
- Routes : creation, edition, storage and display of routes contents
- Tracks : stores and graphically displays tracks
- Communication : fast and light asynchronous communication library with support of both gps and host mode. Connected to a GPS the PalmPilot is a host and, connected to a PC, GPilotS emulates a selectable GPS.
- Upload, download : you select which categories to send to GPS or receive into local databases
- Mark (stores) current position
- Time synchronization : to sync PalmPilot time with GPS time
