dead reckoning algorithms / solutions

Hello All

Me again, flogging a (hopefully not) dead horse.

I wonder if anyone can provide links/guidance/code/insight into dead reckoning programming using the various (relatively) low cost components available to us.

I am thinking of things such as gyroscopes, accelerometers, magnometers etc. At this point I am excluding wheel encoders (since my vehicle is tracked and suffers from slipping tracks) or any form of external input such as beacons or gps etc.

Simple Optical/Rotary Encoder Generator

Was building a simple Rotary Encoder for the ARP platofrm yesterday. Could not find a simple tool to generate the pattern according to my needs, there were some Postscript based tools but they did not work on Windows.

So here is my little script to generate it ...

PHP Code:

header("Content-type: image/gif");
$size = isset($_GET['size'])?intval($_GET['size']):200;
$size1 = isset($_GET['size1'])?intval($_GET['size1']):0;
$count = isset($_GET['count'])?intval($_GET['count']):10;
