This blog deals with different topics regarding the Global Positioning System (GPS). What started out some years ago as a single page with hints and how-to's for Garmin-/Mac-users has turned into a somewhat more general collection of articles about Satellite Navigation. Nevertheless, the Mac-nerd will still find everything he always wanted to know about the use of Garmin GPS receivers with Apple Macintosh computers – but never dared to solder.

The are some introductionary texts about the basic terms and history of the GPS-system:

• Overview about Global Navigation Satellite Systems (GNSS)
• Introduction to the NAVSTAR system (GPS)
• Basic Terms: Waypoints, Routes, Tracks
• Handling your GPS-device/Improving the signal quality 

Support articles regarding Garmin-devices on Macintosh computers:

• Different software for different tasks – an introduction
• Mac-GPS-Software Guide
• Which Garmin should I buy? [to be released in December 2009]
• Big trouble with small cards

These articles have a more philosophical focus:

• Why Garmin?
• Why not to use GPS
