Satellite tracking system for cars appeared not so long ago, but has already managed to spread widely among users. The Americans began to use it, where GPS appeared.
How it works
The principle of operation of devices is simple. A block connected with 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 transmitted to the dispatcher. Later, the satellite car tracking system was upgraded to work continuously and in real time, which made it more convenient.
New systems have a data transmission unit using CDMA and GSM. Well-known networks such as Inmarsat, Globalstar and others also began to function, but their cost was very high.
Satellite vehicle tracking system is based on receivingsignals from the satellite, which is responsible for navigation. GPS is still the leader in this area, although domestic developments of the GLONASS system are already being actively used. Due to the need to introduce GLONASS modules, new devices began to be developed and put on sale that are capable of interacting with two global positioning systems simultaneously.
Device
The main component, which contains a satellite tracking system for a car, is the central unit. All data about the coordinates of the car, all parameters and movement are accumulated there. At first, these blocks were quite large and could only store coordinates.
But today's devices have an integrated microprocessor and a memory block. In addition to coordinates, information about stops, speed, fuel, passengers and much more is recorded. All this data is transmitted to the block by various sensors responsible for individual operations in the machine. The block has an impact-resistant design, which makes it not damaged in an accident.
Advanced functionality
Satellite vehicle tracking system has many advantages. For example, trucking companies can now constantly monitor all of their vehicles at the same time. But the system has gained no less popularity in passenger transportation.
Thanks to it, it is possible to control the speed limit, prevent unauthorized use of transport and not deviate from the setroutes.
The 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 car tracking system). Often, such devices have a “panic button” function, sending a signal in case of an accident, and other features. Despite these characteristics, the devices are quite compact and can be easily installed even on passenger vehicles. Of course, and their cost is much higher than the simple version.
So what to choose?
The most advanced are the complexes operating on 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 cargo transportation over short distances in Siberia, they are used quite often.
From what has been said, it can be seen that the devices for tracking via satellite are different. A large number of models are currently being produced. Devices are selected depending on the tasks that must be solved in the process of use and the conditions of future operation. The necessary functionality is selected and, based on all this, a specific device is selected. Consideras an example, two devices.
Voyager 2 GLONASS satellite vehicle tracking system
With the help of the system, the owner has the ability to fully control the vehicle. With a large selection of modifications, he can adapt the device in the best way for himself.
The instrument is capable of:
- display the vehicle and its direction at any time;
- fix all parking spaces;
- automatically fix route deviations;
- control the exit from the site or city limits, a certain region and country;
- contact the dispatcher;
- has an immobilizer;
- stores up to ten thousand kilometers.
Boomerang Satellite Vehicle Tracking System
This module is a miniature device that can be discreetly installed in a car. Its difference from other monitoring systems is:
- miniature size to prevent attackers from detecting 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 the vehicle from the secret mode to the tracker;
- a unique recharging algorithm when the hijackers cannot "calculate" it by current;
- minimum supply voltage (6 to 32V);
- a powerful antenna that allows you to hidedevice anywhere in the vehicle;
- affordable;
- the ability to be in sleep or active mode.
The developers claim that there have been no cases of theft, when the car was not returned to its owner, for the entire period of operation of the Boomerang system.
