The satellite car tracking system appeared not so long ago, but has already managed to spread widely among users. The Americans began to use it, where GPS appeared.
How does it work
The principle of operation of devices is simple. A unit connected to a space satellite is installed in the machine. All information is transmitted to the control room, where all movements of the vehicle are recorded. Previously, devices could not work online. The coordinates of the car were recorded in the block, and then they were transferred to the dispatcher. Later, the satellite tracking system for cars was modernized, began to work continuously and in real time, which made it more convenient.
The new systems have a data transmission unit using CDMA and GSM. Also, such well-known networks as Inmarsat, Globalstar and others began to function, but their cost was very high.
The satellite vehicle tracking system is based on receiving signals from the satellite, which is responsible for navigation. GPS is still a leader in this area, although domestic developments of the GLONASS system are already actively used.
Due to the need to introduce GLONASS modules, new devices that can interact with two
global positioning systems simultaneously began to be developed and appeared on sale.
Device
The main component that the satellite tracking system for the car contains is the central unit. All data on the coordinates of the car, all parameters and movement are accumulated there. At first, these blocks were quite large and could only save coordinates.
But today’s devices have a built-in microprocessor and a memory unit. In addition to coordinates, information about stops, speed, fuel, passengers and much more is recorded. All this data is transmitted to the unit by various sensors responsible for individual operations in the machine.
The unit has a shockproof design, so it is not damaged in an accident.
Advanced functionality
Satellite tracking system for cars has many advantages. For example, trucking companies can now constantly monitor all their vehicles simultaneously. But in passenger traffic the system has gained no less popularity.
Thanks to it, it is possible to control the speed limit, prevent unauthorized use of vehicles and not deviate from the set routes.
Prices for these devices are very different and depend on technical capabilities. The cheapest options are those that work offline. But more and more modern devices operate in real time. The most advanced ones have the ability to use both GPS and GLONASS (for example, the Voyager 4 satellite tracking system for cars).
Often such devices have a “panic button” function, sending a signal during an accident, and other features. Despite these characteristics, the devices are quite compact and can easily be installed even on passenger cars. Of course, their cost is much higher than simple versions.
So what to choose?
The most advanced are the complexes operating via satellite communication systems. The highest here is not only the price, but also the data transfer. Therefore, such devices are common only in the Far East, Siberia, Africa and other places where terrestrial communication systems may not work.
The same can be said about VHF systems. For transportation over short distances in Siberia, they are used quite often.
It can be seen from the above that the satellite tracking devices are different. Models are currently produced in considerable numbers. Select devices depending on the tasks that should be solved in the process of use and the conditions for future operation. The necessary functionality is selected and, based on all this, a specific device is selected.
Consider two devices as an example.
Satellite tracking system for cars Voyager 2 GLONASS
Using the system, the owner has the ability to fully control the vehicle. With a large selection of modifications, he can adapt the device in an optimal way for himself.
The device is capable of:
- display transport and its direction of movement at any time;
- fix all parking places;
- automatically record deviations from the route;
- control travel outside the site or city limits, a specific region and country;
- contact the dispatcher;
- has an immobilizer;
- saves up to ten thousand kilometers.
Satellite tracking system for cars "Boomerang"
This module is a miniature device that can be installed covertly in a car. Its difference from other monitoring systems is:
- miniature size, thanks to which attackers will not be able to detect it;
- a unique algorithm thanks to which the owner can track the location of his vehicle at any time;
- free software, due to which the car owner can transfer vehicles from secret mode to tracker;
- unique recharging algorithm when hijackers cannot “calculate” it
current; - minimum supply voltage (from 6 to 32 V);
- a powerful antenna that allows you to hide the device anywhere in the car;
- reasonable price;
- the ability to be in sleep or active mode.
The developers claim that there were no cases of theft when the car was not returned to its owner for the entire period of operation of the Boomerang system.
