How does it all work?

In orbit around the Earth are a number of satellites that make up the Global Positioning System or GPS. If you have a receiver in a vehicle and it can locate at least 3 of them, it can work out where it is. This is done by a process called trilateration, put simply your receiver calculates how far it is from a satellite and draws a circle where it thinks it is. It now repeats that at least twice and where those circles overlap is its location.

So now it knows where it is, it needs to tell tell our server so we can place it on the map. It does this using GPRS (Radio Data) and the internet. A data transmission unit is housed in the same box as the receiver and at set times it takes the location from the GPS receiver and transmits it to any nearby Cellular Network’s mast. This then relays it via the internet to a computer server which can be anywhere in the world. When we first started supplying trackers in the nineties most companies hosted the server themselves, but these days you don’t have to have the hassle. Modern computer devices let you go and ‘peep’ at your data on a professional hosted server, just using an internet browser.

What does the hardware cost?

First of all, don't be shocked that this website actually publishes its prices. You will find no "Call the team for an instant quote" rubbish here! These are the prices we charge, no extras, no surcharges and no VAT. Below is the cost of purchasing one of our standard tracking devices.


AVT11 Standard Tracker (inbuilt aerials)


Inexpensive Tracking Device

Our base and most popular unit with in built aerials, because the aerials are inside it clearly it is the easiest unit to install, just requiring to be mounted where it can electrically see the sky i.e. Label side up (for example on/under the dashboard, inside a glove compartment, rear parcel shelf, a truck side locker, or under a fibreglass / wooden roof).. 

The AVT11 is splash proof and also has an internal backup battery (lasts around 2 hours). It needs a 10-30 volts supply and if you are on our the right rate, it can send a message when equipment like the PTO, Tilt / Tip mechanism, Engines, Locker or roof lights are used.

Cost £75 (All in)

AVT12 Weatherproof Tracker (inbuilt aerials)


Weatherproof Tracking Device

The AVT12 was designed for our marine customers but often finds its way onto utility vehicles, sports vehicles and motorcycles. With its Weatherproof housing (to IP67) this is our most rugged unit and is also perfect for Plant or Boats. It can just be mounted on a roof, or hidden away (label side up). Then it is just a case of running power to it.

It comes complete with internal battery (lasts around 5 hrs.), connecting cables and instructions. It needs a 10-30 volts and if you are on our the right rate, it can send a message when equipment like the PTO, Tilt / Tip mechanism, Engines, Locker or roof lights are used.

Cost £85 (All in)


All items can be ordered by email, or phone and then invoiced.


Other Equipment

External Aerials: The two units above have built in aerials and for most installation these are more than adequate. However for some vehicles that spend some time a good distance from built up areas an external aerial mounted high up will increase range considerable. Each installation will be different, but as a good guide a tracker with external aerials sockets cost £65 and the aerials will add between £25 and £45 extra depending on size, mounting method etc. Please contact us to discus this option if you feel you need it.

Mounting Brackets: Most installations are achieved with a small strip of Velcro (other brands are available), or plastic wraps. However for 'High Performance Vehicles' that may encounter occasional high 'G' force, we recommend using a simple metal 'U' bracket. As a number of people have said they would like to buy rather than make, we have had some manufactured in aluminium and they are available to you at what it cost us, which was £9 each.

Theft Deterrent: Let us be clear there is not a device made be it ours, or any other companies, that can stop someone stealing your vehicle and any salesman who tries to tell you different is a liar! That said a well hidden installation and some common sense can help a lot. If you are on the right monthly rate and have an anti-theft device already installed, you can run a feed from the siren to our unit and it will send you a message when it goes off.

A micro, or magnetic switch on a vehicle or locker door, even a simple inexpensive under-carpet pressure pad can do the same thing. The simple act of geo-fencing your home / work compound will allow you to be emailed if it leaves the area and there are many more options, just talk to us to find out what others have done.
