For further information and Paralog-NMU specific support requests please contact [email protected]. To download Paralog-NMU, please see Alti-2's web site.

Free Online GPS Viewer

A free Online GPS Viewer with support for FlySight and GPX tracks has been made available online by Paralog.

Tracks can easily be uploaded to the viewer using Drag&Drop where it can be be explored in an interactive chart or in an interactive 3D view. The interactive chart also offers comfortable editing capabilites for the uploaded track, e.g. cuting lead ins and leads out and setting exit, open and landing points for better visualization.

The viewer offers automatic exit/open/landing detection and track analysis as seen in Paralog.

Note: Please be aware that the viewer uses a reduced resolution and simpler algorithms than Paralog for performance reasons. Results may therefore differ.

PPCPPC - The Paralog Performance Competition

Online Competition

The competition will have three different ways of judging (depending on what you like) for time, distance or highest (ground/forward) speed, and doesn't use time, but rather a set competition window of 3km/2km for judging.

Though still subject to wind, it should be a more honest comparison/friendly competition (or just monitoring your own performance) than the time based method other websites/competitions use.

In combination with the (either full registered version or demo) Paralog, users will be able to upload their tracks from either GPS (time/distance/speed) or Neptune and ProTrack (time).


Next to the online competition, the website can also serve as a base for your dropzone competition on any of the sub-disciplines. All you need is a plane, people wanting to fly, some GPS or Neptunes/ProTracks and a working internet connection.

If you want to organize a cool competition at your home DZ, one email is all it takes to get started!


There is no setup fee or any other charge. For use in a dropzone event a version of Paralog 5.2 with a free, temporary event-license is the only thing you need as an organizer. For the (non event) competition on individual basis, the a registered or demo version of Paralog 5.2 will be all you need.

Though respecting the time and effort put into this, it is of course appreciated if you choose to order a full version of the software (with which you also get access to the many other exiting features).

Both in the demo and full version, all you need to do it hook up your GPS, import the data and click the submit to PPC button. The software will do all the cleaning/cutting of the data to the needed bits for you. Meaning there is no complex technical nerdness required to participate.

Detailed instructions are available on the PPC web site.

Paralog at the PIA Symposium

Paralog Main Screen A new version of Paralog, the world's leading skydiving logbook and flight analysis software, has been introduced at PIA and was well received. Most noticeable changes are the fresh user interface, integrated 3D view of GPS tracks, a companion version for Windows Mobile and support for the new N3 by Alti-2.

Infrared support on OSX

As most Neptune users on OSX are painfully aware, support for IR-USB adapters has been suspended starting with Tiger. David Fowler found an interesting solution to this problem:

"Some time ago I corresponded with you about using IR adapters with Paralog on Macintosh computers (for importing data from my Neptune). At the time, the only solution I found was to either import the data to a Windows machine and then transfer the file to my Macintosh, or to use my old PowerBook G3 which had a built-in IrDA port (and again transferring the file to my main Macintosh computer).

I have since come up with a direct solution. The two problems I had were 1) existing USB IrDA adapters don't have Macintosh compatible drivers, and 2) Serial IrDA adapters require more power than is available from USB-to-Serial adapters.

The serial IrDA adapters use the DTR and RTS lines for power. The problem is that these lines are signal lines that were never intended to supply device power. Actual serial ports generally drive these lines at between 9 and 12 volts. USB-to-serial adapters, however, drive these lines at only 5 volts, which is not enough to power the IrDA adapters.

I solved the problem by building a simple 'power' box between the USB-to-serial adapter and the IrDA adapter. Inside the box, I simply connected a 9-volt battery between the ground (-) and DTR & RTS pins (+) on the IrDA side (leaving the DTR and RTS pins unconnected on the USB-to-serial side)."

Neptune supported on Linux

Neptune on Linux Thanks to the determination of Robie Basak, some bugs have been fixed in the Linux IR stack, enabling Linux to connect with Neptune. This fix should make it into the next kernel, until then contact us for further details and instructions.

Paralog 3.1 released

Paralog 3.1 has been released, further leveraging the integration of GPS and Google Earth:

  • By integrating the latest version of GPSBabel, Paralog improves support for Garmin and Magellan devices and adds support for Garmin Training Center XML and NMEA.
  • In addition to extracting horizontal distance and speed, glide ratio, course, etc. from the raw GPS data, Paralog can now automatically skip old tracks downloaded from GPS and correctly number your jumps. Improved speed calculations result in more accurate speeds.
  • Jump Profile Goggle EarthExport of jump tracks to Google Earth has been improved by adding data points to the track. The relevant data can now be displayed along the 3D track as shown in the screenshot to the right.
  • 3D tracks of your jump in KML format for Google Earth can now be included in your online jump log.
  • Jump Profile Cursor AltitudeSupport for evaluating tracking and wingsuit jumps as well as swoops based on time or altitude. A user definable 'range' can be marked on the track to exactly measure e.g. distances covered over this range. This is the most flexible solution for evaluating individual flights and judging competitions, giving full control to the user without requiring an Internet connection!
  • QNE (ground level) can be overridden so that swoops do not end in the ground when displayed in Google Earth (This really looked ugly!).

Mac Universal LogoSupport for Intel-based Mac computers has been introduced with Paralog 3.1.

Paralog 3.0 released

GpsBabelIn addition to reading data in GPX format, Paralog now supports direct download of GPS tracks from compatible units through the integration of GPSBabel. Currently, download from Garmin and Magellan devices is supported, while DeLorme GPL files can be imported directly into Paralog; others can be added based on demand.

Google Earth has been integrated with Paralog for interactive 3D display of GPS tracks on Windows and OSX. Google Earth combines satellite imagery and elevation data for the whole planet creating a virtual globe inside your PC with high resolution data available for most populated places. Google Earth allows you to zoom, pan, tilt and rotate your view to explore the earth and even fly across the landscape.

GoogleEarthThe image to the right shows a screenshot of a canopy flight over Raeford, NC rendered in Google Earth. As a static image can not convey the interactive possibilities of Google Earth, install Google Earth and launch this file to explore the endless capabilities of Google Earth.

With Paralog, viewing a GPS track in Google Earth is just a mouse click away: Simply click the 'Show 3D-Map' button in the new jump profile view to export and open your jump track in Google Earth and view it interactively in 3D using all the features of Google Earth: tilting, panning, zooming, even flying along your flight path! You can save and share your tracks and add your own annotations.

All this works with the free edition of Google Earth. The 'Plus' version, which is usually required to import GPS data is not necessary, saving you $20/year in registration fees!

Other enhancements include an improved user interface, support for the new Skytronic GFX, automatic logging of rig information based on the jump type recorded in your freefall logger and quickly creating and changing log files for better support of multiple loggers.

Paralog 2.1 released

Working closely with well-known wingsuit flyers and swoopers, GPS support has been introduced with Paralog 2.1. Paralog can import GPS data in the standardized GPX format, automagically extract the usual jump details like exit and open altitude, delay, etc. from the raw GPS data and display all the additional information available from GPS (horizontal distance and speed, glide ratio, course, etc.) in the enhanced jump profile view. This new and unique feature makes Paralog the first software to leverage the possibilities of modern of-the-shelf GPS units specifically tailored for the requirements of skydivers!

Another major enhancement is the 'Template Based Jump Log Export': Jump logs can be exported to arbitrary formats (e.g. HTML, CSV or SSA) through flexible templates which can be easily customized by the user. The integrated FTP client allows for easy and seamless uploads of the generated files, e.g. to a web server. Four ready-made templates are included: HTML format using a plain, tabular view, HTML format using a menu driven, fully linked view with totals, jump details and lots of charts and graphs, CSV format to import into spreadsheet software, e.g. Excel and SSA format to generate video subtitles with VirtualDub. Note: This upload feature has been replaced by synchronization with

NeptuneDownloader for PocketPC 1.1 released

A new version of 'NeptuneDownloader for PocketPC' has been released. Version 1.10 of NeptuneDownloader for PocketPC' now supports Windows Mobile 5.0 and (finally) the Compaq/HP iPAQ product line. 'NeptuneDownloader' is a utility for to download, display and save Neptune data for later import into Paralog.
