IMPORTANT NOTE ABOUT SUPPLYING POWER TO YOUR GPS

Many of Garmin's GPS receivers will be severely damaged if you attach them to a 12 volt power supply (as is provided by a lighter socket in automobiles). Yet some will work just fine. This section provides you with some information on how to provide external power to your GPS safely.
 

HOW TO CONSTRUCT YOUR CABLE

Two separate documents are available in PDF format to assist you in constructing your cable with the connectors you obtained. You can download files for constructing cables with the eTrex/eMap/Geko or Rino connectors.

STUDY OF THE ACCURACY OF AVERAGED NON-DIFFERENTIAL GPS MEASUREMENTS

For quite some time, we have been trying to find a good source of data to answer the question of "how long is long enough" when averaging the position of a static GPS position over a length of time to obtain a given level of accuracy. Failing to find information which adequately addressed the issue, we conducted our own little experiment, gathering 568,830 positional measurements from a Garmin GPS 38 and basically analyzing the heck out of the resulting data. If anything, we were really quite surprised at how well the question could be answered. For more details (and nifty charts!), please read the little report we wrote on the experience. Note that this study was done when Selective Availability (SA) was turned on. Now that SA has been disabled, the results are less relevant than they once were.
