and buy one of their Trac units. It can be set to send the GPS co-ordinates at specified intervals to a server via GPRS.
I have created my own GPRS/GPS tracking system using an older version of this product. What you need is a GPS/GPRS module, a GPRS data SIM card (data plans give you GPRS for < 0.5c per kB compared to 2c per kB or timed for normal plans), and a computer with a fixed IP address.
The computer IP address and port is programmed into the unit, and the unit is set to send GPS information every 5mins. A program on the computer listens on the port, and logs the GPS data.
If you do not have a fixed IP address I think there are some services out there that will provide one, redirected to you.
How much are you looking to spend? At a guess the Trac unit will cost you
150+ pounds and the GPRS data plan around $10 per month. I have a simple logging program that you could use, but any TCP logger should be fine.
I thought that this just offered a fixed domain name, which then resolves to your variable IP address. Worthless if you can't do a DNS lookup from the GPRS.
You could use this as a query site to obtain the IP of the computer at the time.
You used to be able to obtain a fixed IP through them, and install a small prog on computer that registers your IP every time you connect to the net, and every hour or so.
Probably have to pay for a fixed IP now. Was free once.
