Satellite car tracking system: device, operating principle, examples
The satellite tracking system for cars appeared not so long ago, but has already spread widely among users. It began to be used by Americans, where GPS appeared.
How does it work
The principle of operation of devices is simple. In the car is installed a unit connected to the space satellite. All information is transferred to the control center, where all vehicle movements are recorded. Earlier 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 block of data transfer using CDMA and GSM. Also became such well-known networks as Inmarsat, Globalstar and others, but their cost was very high.
Satellite car tracking systemIt is based on receiving signals from the satellite, which is responsible for navigation. GPS is still the leader in this area, although the domestic development of the GLONASS system is already actively used.
Because of the need to implement GLONASS modulesbegan to develop and appear in the sale of new devices that are able to interact with two systems of global positioning simultaneously.
The main component that containssatellite car tracking system, is the central unit. There all the data about the coordinates of the car, all the parameters and movement are accumulated. At first these blocks were rather large and were able to save only the coordinates.
But today's devices have built-ina microprocessor and a memory unit. In addition to coordinates, information about stops, speeds, fuel, passengers and much more is recorded. All these data are transferred to the block by various sensors, responsible for individual operations in the machine.
The unit has an impact-resistant design, so it is not damaged in an accident.
Satellite car tracking systemhas many advantages. For example, trucking companies can now constantly monitor all their vehicles at the same time. But in the passenger transportation system has won no less popularity.
Thanks to it, it is possible to control the high-speed mode, to prevent unauthorized use of transport and not to deviate from the delivered routes.
Prices for these devices are very different and depend ontechnical capabilities. The cheapest options are those that work offline. But more and more modern devices function in real time. The most advanced have the ability to use both GPS and GLONASS (for example, the satellite tracking system for cars "Voyager 4").
Often such devices have the function of "alarming"buttons ", sending a signal during an accident, and other possibilities. Despite such characteristics, the devices are quite compact and can easily be installed even on cars. Of course, and their cost significantly exceeds the simple versions.
So what to choose?
The most advanced are complexes,functioning on satellite communication systems. The highest here is not only the price, but also the transfer of data. Therefore, such devices are distributed 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 freight transportation for short distances in Siberia, they are used quite often.
From what has been said, it can be seen that the tracking devicesthrough the satellite are different. Models are currently produced quite a number. Select devices depending on the tasks that are to be solved in the process of use and conditions of future operation. The necessary functional is selected and on the basis of all this select a specific device.
Let's consider two devices as an example.
Satellite tracking system for cars Voyager 2 GLONASS
With the help of the system, the owner is able 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 the transport and direction of its movement at any time;
- fix all parking lots;
- automatically record deviations from the route;
- to control the departure outside the site or city limits, a certain region and country;
- contact the dispatcher;
- has an immobilizer;
- saves up to ten thousand kilometers of run.
Satellite tracking system for cars "Boomerang"
This module is a miniature device, which can be installed in the car secretly. Its difference from other monitoring systems is:
- A miniature size, through which intruders can not detect it;
- a unique algorithm, through which the owner at any time can track the location of his vehicle;
- free software, due to which the car owner can transfer the vehicle from the mode of the secret to the tracker;
- a unique charging algorithm, when hijackers can not "calculate" it
- minimum supply voltage (from 6 to 32 V);
- A powerful antenna that allows you to hide the device anywhere in the car;
- affordable price;
- the ability to be in sleep or active mode.
The developers assure that the cases of theft, when the car was not returned to its owner, during the entire operation of the system, "Boomerang" was not recorded.
