Global Positioning System

Thus, in 1990 Annual sales of anti-theft alarm in Europe amounted to 10 million sets per year. However, these impressive sales abnormal unilateral radio-controlled car alarms could not remain indifferent the world's carmakers. Was launched active promotion for the fight for the silence at the legislative and societal level. For example, the adoption of a law prohibiting the installation of loud sirens on the "city" cars. All these measures have reduced the popularity of abnormal unilateral alarms. In 1993, David T.

Instantly developed a unique system of ProCar One. Originally conceived in 1991, the idea was to "stop the robbers from using the security system that would determine the owner of the car on a special resonating map hidden in his pocket. " The system was subsequently improved, and in 1993 added many features so ProCar One was recognized as the ugonostoykoy and, unfortunately, an expensive car alarm system. Appeared in 1995, two-way car alarms have several advantages compared with standard car alarm: a large range warning motorist about the hijacking (1000 m) and a wider range of additional functions – informative key fob, remote autostart. But this, unfortunately, does not permit recovery the market of security systems, as an initial set of consumer characteristics bilateral alarm systems had been destroyed rigid legal restriction of power transmitter, which forced to cut range of up to 120 m. This was a determining factor in the refusal of the product. However, a good alternative to the functionality of bilateral alarm systems are GPS-signal, allowing to determine the coordinates car up to 5 meters. Satellite tracking of vehicles is based on the work of gps (Global Positioning System – Global Positioning System).

Initially the system of tracking and navigation appeared in Europe in the 70-ies of xx century in the military purposes, but for civilian purposes has been applied only in the 90 years. In parallel with the development of automotive GPS-signal systems, since 1991, began the march on the world standard gsm (Global System for Mobile Communications), but the GSM-standard and managed to revive the market radio channel car alarms. Producers have responded to this issue of GSM-module and adapted to it at first unilateral and then bilateral radio channel car alarm, calling them the GSM-signal. Thanks GSM-alarms you can track the status of the car, even while outside the country, and in addition to its "core benefits", they provided a number of useful options, for example, can give the command to include motor or opening the doors via the Internet. New stage in the development of alarm systems provide satellite-based GPS-GSM signaling. According to statistics, the highest rate of return falls on cars with built-in GPS-GSM search system. The only obstacle to the widespread dissemination of satellite GPS-GSM signaling is the high cost of not only the product itself, but also a monthly fee. Now being paid a lot of attention to new developments in the identification of car owner. Immobilisers new type will be a worthy alternative to existing models on the market of security systems. For example, a well-known biometric immobilizer "Voodoo (WooDoo) using the scanner on the dashboard (or covertly installed) learns his master's fingerprint. The development of insurance legislation and a general strengthening of the legal systems of many countries (such as those eu, U.S., Japan, China), as well as the introduction of most automakers established security systems in a complex avionics, of course, reduced the number of thefts, but did not exclude them as a class of crimes.
