INTRODUCTIONIt is developed by the U.S. Military commonly known as GPS (Global Positioning Satellite). This type of surveillance system calls for the following four elements. They are:A TransmitterA SatelliteSender/ReceiverSoftware and Location DecoderThe reason GPS tracking is becoming so popular these days is that it is possible to conduct surveillance that in unmanned. That is, the equipment tracks the movement of the vehicle and its stop locations. Investigative agencies in the USA are starting to offer such services and it's time all investigative agencies become familiar with what this technology is all about.1.1 A Little History of Vehicle Tracking Non-GPS Tracking SystemsIn the late 1960's and early 1970's, car trackers became available in the private sector. These early systems consisted of a receiver and a sender with at least two antennas that were placed on the vehicle. The surveillance investigator would keep the receiving end of the equipment with him in his vehicle. Basically all these units would do is tell you which direction the vehicle was located in and maybe the distance from the target vehicle. If you lost a vehicle, this type of system made is easier to locate the vehicle but they had their limits. It's important to point out that these units could not reveal the actual location of the target vehicle. They merely indicated which "direction" the target vehicle was in from the surveillance vehicle's location and the distance. One of the major problems with these units is that they had a limited range. Not only that, in huge metropolitan areas with tall buildings and lots of radio traffic, they rarely performed as needed and the range so sort in most instances, they become rather useless.These non-GPS car tracking systems have been improved over the years and the range on them somewhat expanded but they still have their limitations. Understanding their limitations is important but they can still be used in real time mode to help locate a lost vehicle.Let us go over each element of what is involved in AVL or GPS tracking.

Fig 1.1 (a) A Photo of an Early Car Tracking System

Fig 1.1 (b) Pro Track One Non-GPS Tracking System1.1.1 The TransmitterAn electronic transmitter that sends out signals from the vehicle. Naturally, this equipment will have to be placed somewhere on the vehicle in order for a signal to be transmitted.

Fig 1.1.1(a) The TransmitterThe typical equipment used for this employs very strong magnetic mount. You walk up to a vehicle and quickly place the entire box on the underside of the vehicle. 1.1.2 The SatelliteA Global positioning satellite obtains signals from the transmitter device placed on the vehicle. The use of only one satellite will give an accuracy rating of about 100 feet. This can be improved by using triangulation math which uses three satellites and gives more pinpointed accuracy down to about ten meters. Up until a short time ago, this was extremely expensive technology. However, the U.S. Department of Defense has placed a series of 24 Global Positioning System (GPS) satellites in orbit around the earth. These GPS satellites broadcast signals that contain time and identifier codes. GPS receivers use an antenna to acquire these signals from multiple satellites to determine a person's position, altitude, speed and direction of travel. These satellites are now being used by the public and can be used as online map plotting tracking in your vehicle as well are used as mobile vehicle locators in surveillance work.1.1.3 The Sender and ReceiverHere is where options and different configurations come into play. There are what are called real time satellite tracking systems and none real time systems. Real time tracking systems tend to be more expensive than tracking systems that are not real time. With the lower end systems, you cannot plot the location as it actually happens. With real time tracking equipment, you install software on your computer and must have a separate unit attached to your computer that will receive the satellite signal. With this type of set-up, you are in a position to track a vehicle as its moving. The Protrack GPS system is one of the most popular configurations for real time tracking. The black box within the magnetic mount beans a signal to a GPS satellite and then receives its location. That signal is then forwarded through a cell phone connection to the user's computer. In none-real time tracking systems, the satellite signal is send back to the original sending box and stored for latter pickup. With this simpler type of system, you retrieve the box after the surveillance and then load the data from it into your computer. The Car Tracker is one of the more popular non-real time GPS tracking systems on the market today. Understanding the difference between real time GPS tracking and non-real time tracking is simple. Real time tracking let's you obtain the results right now from your computer desktop. Non-real-time tracking requires you to pick up the magnetic mount after the surveillance and obtain the results then.

Fig 1.1.3(a) The ProTrack GPS SystemAt first look, real-time tracking seems to be the way to go. However, there are several draw backs to it. First, real-time tracking equipment is going to cost substantially more. Secondly, there are more signals that can get lost in the process. Remember, the signal is sent back to the magnetic mount then forwarded to the subject computer. An extra transmission step is involved. Any time that happens, more things have the potential of going wrong and there will be a greater potential of loss of signal in such a setup.Power Supply Issues No matter what type of GPS tracking system one uses, some sort of power supply is needed. In the typical fast-action magnetic mount systems, standard self-contained battery power can be used. However, you have a limit to the amount of power time you have. Products like Car Tracker have an optional fuse box hardwire that can be wired into the vehicle power system but this, of course; requires position of the vehicle for such a technique. However, hardwiring can sometimes be employed in situations in which parents want to track their children's location for an extended period of time. 1.1.4 The Software and Location DecoderA decoder converts the data received into an address. The location information which is generally in latitude and longitude is plotted with mapping software so the user can obtain actual maps of the location of the target vehicle. Thus computer generated map plotting programs are used to convert the latitude and longitude readings into an address on a computer generated digital map. This requires installing specific software onto your computer that w
