The Anti-Tracker The AntiTracker is a new concept in GPS tracking systems. The idea behind
the AntiTracker is that manu units in the field do not need to have their
positions reported back. These field units are however interested in where
the units being tracked are.
Think of marathon race. The first and last runners in the race are being
tracked thanks to trackers on vehicles following the race. Each of the
checkpoints is stationary, but they want to know when the first runner will
be reaching them, and how long it will be until the final runner passes
them.
This allows significant cost
savings in terms of not only equipment capital costs, but also in terms of
operational costs including licenses and batteries.
With this in mind, Radioactive Networks have just produced what we are
calling the 'Anti-Tracker'. Rather than develop the display interface, we
have decided to use a commercially available interface - a simple GPS
reciever.
Two Models
Initially, Radioactive Networks will be releasing two versions of the
AntiTracker. They will be :-
Basic - The ability to display positions on a GPS receiver with NMEA
input - meaning that it will not work with the entry level Garmin eTrex. The
design also uses two embedded processors, rather than a single integrated
processor.
Pro - The Pro version of the AntiTracker contains all the
capabilities of the Basic unit, except it will upload to GARMIN GPS
receivers in BINARY format, meaning that it will work with the basic Garmin eTrex.
An upgrade will include the capability for ICONs to be also uploaded to the
GARMIN.
Download
You may download the AntiTracker Source Code and HEX files from here. The files are free for non-commercial amateur
use. The WORD document contains the full license.
Implemented Packets
For the technically minded, we will now include information on the packets that this
device will decode -
Standard Position Reports
Standard Position Reports with Timestamps
MIC-E Position Reports

Standard Object Reports

This project would not have been possible without the assistance of the
members of the PicSig on TAPR.ORG. These members put up with my stupid
questions, offering whatever assistance was required.
