Tracking

TrackerTag can track where you are and send this information to a website. You can configure how often the position should be sent:
  • travelled distance
  • passed time
  • change of direction
  • change from moving to standing still and vice versa
You can also configure what counts as a change from moving to stopped (how long there should be no movement).
The triggers can be configured in the page "tracker" in the settings dialog.
To handle the sent information, you will need a server that processes the information. There are two ways to do this:
  • using a GPSGate server
  • using your own webserver, handling the data by php, asp or something similar.


GPSGate

GPSGate.com is supported as tracking server.
To use GPSGate you need to make a user accont on www.gpsgate.com. This username and password can be entered in the settings dialog. You also need to set the line "Use GPSGate server" to "Yes".


Using your own server


When you have access to your own webserver, you will have to write two pages: one to receive the location information, and one to show the information to a webbrowser.
Here are the arguments that trackertag uses when calling your webserver:
imei=%S&lat=%S&lon=%S&status=%c&speed=%S&course=%S&label=%S&tripid=%S

So it will look something like this:

http://www.myserver.com/gpstracking/storesql.php?imei=123456&
lat=51.23342&lon=4.22233&status=A&speed=22&course=325&label=bike
&tripid=20080930200159


Speed is in knots, course in degrees. Tripid is unique every time you start TrackerTag. Tripid can get a new value after not moving a certain time (30 minutes at the moment).

Aspicore has some example scripts how to store this information, both for php and asp. Note: TrackerTag does not talk UDP, just HTTP (at the moment).

See www.aspicore.com/en/PHP_tools.asp for PHP and www.aspicore.com/en/ASP_tools.asp for ASP.

If you want to use GoogleMaps to show the information of your location, you might want to look at these pages: http://econym.googlepages.com/index.htm. Or check www.systemsevendesigns.com/phoogle to see if it helps you.

This is an example what the result could look like using GoogleMaps, with different colors for different trips (using tripids):
