This program was developed with a sailplane pilot in mind, but can be used in any situation that GPS position data are available for logging. It is a combination of a navigational aid with a moving map, needed altitude and speed to fly computations, and a data logger. Data are logged in a coma delimited, or International Gliding Commission formats. When logging in IGC format, the program can generate all necessary header and task as well as security related records.
Original version was developed to run on a DOS operating system computers such as HP 100LX. This program is no longer being enhanced. It has been superceded by one running on Windows CE based devices. It is targeted for PocketPC (PalmPC) form factor which is more useful in glider cockpit, but version running on Handheld PC (with keyboard) form factor is also now available for OS 2.11 and higher. A fully functional program version for Windows PC is also available for training and file development purposes.
If you are looking for software of this type running on Palm operating system take a look at SoaringPilot-Final Glide Computer. The name similarity is purely coincidental (except for logical relationship).

Support for FAI certified loggers
Even though GPS_LOG WinCE is a complete logging solution adhering to all IGC standards that are possible on a WinCE platform, it is not certified as such by IGC. For situations where you have an IGC certified logger, you can use GPS_LOG WinCE to define flight declaration and transfer it to such a logger. You need a separate shareware module for that available from here. Currently FLARM, EW logger, Volkslogger, Colibri, GPS_NAV and Cambridge 300 series modules are available. Colibri module works also for Posigraf, LX7000proIGC and other LX... machines
Some maps, turnpoint files and conversion programs mostly sent in by others can be retrieved from here. These are provided "as is". I take no responsibility for their accuracy. If you feel like e-mailing me more files for putting on this server, e-mail them to me with any relevant information including whether your name on the web page (will appear as default as supplier) should be made into a link to some website.
How to generate map files if "I can not find what I need". An example of a map that can be displayed by GPS_LOG WinCE is shown on the right. This is a composite image of a full map in the inset and a partial view as displayed by the PC version of the program. You can download this map.
Some other examples -part of map of Germany available on samples page.
Part of South-East Pyrenees and Catalunya map also available from the samples page
(Click on the images to see full size).
Other maps waypoint files and converters are also available on the samples page
Distribution package for the PC version of the program includes utilities that help map creation from internet available data.

The archive with this spreadsheet includes also parabolic data for a variety of gliders.

Bluetooth compatibility: GPS_LOG WinCE was tested with iPaq HP1940 and a Pharos Bluetooth iGPS-BT unit. You should use the Bluetooth outgoing serial port for communication. In the above test case it is COM5 and 4800 baud. Program versions 184.108.40.206 and higher are more reliable with Bluetooth connection than earlier ones. Bluetooth was also shown to work in iPaq 2210 and Fortuna Electronic GPS combination. In some cases you need to check "Continuous" checkbox in NMEA setup for reliable connection
Please click on this link for some Bluetooth related issues.
Download latest versions. Choose appropriate processor, or package:
Warning: I had a couple of reports indicating that this program may not run properly on iPaq hx2110 devices. Application hardware keys become frozen and unusable even after program exit. This problem was also reported to have been fixed - use alternate keys method in keys options.

PNAs do not contain all the support functionality that is in Windows
Mobile. GPS_LOG in principle will not run on them. The only chance is to
use the PPC2003 version and add dlls contained in the archive linked to
on the right to the \Windows folder of a PNA, or the same folder as the
In order to install the PPC version on a PNA you will probably need to extract CAB files from the archive, transfer them to a PNA, and execute them on the PNA.

WinCE is NOT a FAI approved logger:
IF you are using GPS_LOG WinCE version 188.8.131.52 or later you need to use validation program version 17 (posted 13 Nov. 2004) or later.
