GPS real time tracking principle

For understand the principle of GPS real time tracking, let watch this video that sharing the information with us.



This GPS tracking device is a portable type that located to the car by magnet. It is easy to remove and locate to the vehicle.

Choose The Correct Device

The picture is shows technically how the GPS tracking signal flow. The GPS tracking device that install on vehicle use to determine the precise location of the vehicle. The location data will be transmitted to central location data base by internet connection, GPRS, radio or satellite modem embedded in the unit, this allow the vehicle location to be displayed against a map backdrop in real time or recorded location data will analyzing by using customized software.

As a customer we must alert about type and usage of device before purchasing the device. There are same function but difference categories. GPS tracker can divide for three categories:
GPS data loggers
This unit usually as a portable spy device. The function simply logs the position of GPS device located at regular intervals in its internal memory. Let say, you put the device on your vehicle that your son bring it to visit his friend for somewhere location. After your son return home, you can check the GPS tracker data by downloading to your computer and analyzing the track list, now we know what the thru where he go. GIS software is an aid to over impose their paths over a map.
Data pushers
GPS data pusher device usually fixed to the vehicle. The device will push or send the data position at regular intervals to determine server for instantly analyze the data. Today many company provide GPS data push technology services for business environments. GPS tracking systems often configured to transmit location and telemetry input data at a set update rate or when an event (door open/close, auxiliary equipment on/off) triggers the unit to transmit data.
These systems suitable for extra surveillance vehicle security, transportation services, private vehicle security and race control. For example stolen vehicle searching. Owners of expensive cars can put a tracker in it, and "activate" them in case of theft. "Activate" means that a command is issued to the tracker, via SMS or otherwise, and it will start acting as a fleet control device, allowing the user to know where the vehicle is. A delivery or taxi company may put such a tracker in every of its vehicles, thus allowing the staff to know if a vehicle is on time or late, or is doing its assigned route. The same applies for armored trucks transporting valuable goods, as it allows to pinpointing the exact site of a possible robbery.
Data pullers
Data Pullers are coming into more common usage in the form of devices containing a GPS receiver and a cell phone which, when sent a special SMS message reply to the message with their location. The data from the GPS tracker device provide by user itself and server analyzing the data transmitting by user.

Common Purpose of GPS Vehicle Tracking Device

GPS (Global Positioning System) gadget recently used as vehicle navigation system. GPS navigation device to acquire position data to locate the user on a road in the unit's map database. Difference with GPS Vehicle Tracking Device give users the ability to monitor a vehicle vehicles from a remote location. Vehicle tracking systems integrate several security systems, popular in consumer vehicles as a theft prevention and retrieval device. Other scenarios in which this technology is employed include:

• Stolen Vehicle Recovery: Both consumer and commercial vehicles can be outfitted with RF or GPS units to allow police to do tracking and recovery. In the case of LoJack, the police can activate the tracking unit in the vehicle directly and follow tracking signals.

• Surveillance: A tracker may be placed on a vehicle to follow the vehicle's movements.

• Fleet Management: When managing a fleet of vehicles, knowing the real-time location of all drivers allows management to meet customer needs more efficiently. Whether it is delivery, service or other multi-vehicle enterprises, drivers now only need a mobile phone with telephony or Internet connection to be inexpensively tracked by and dispatched efficiently.

• Asset Tracking: Companies needing to track valuable assets for insurance or other monitoring purposes can now plot the real-time asset location on a map and closely monitor movement and operating status.

• Field Service Management: Companies with a field service workforce for services such as repair or maintenance, must be able to plan field workers’ time, schedule subsequent customer visits and be able to operate these departments efficiently. Vehicle tracking allows companies to quickly locate a field engineer and dispatch the closest one to meet a new customer request or provide site arrival information.

• Field Sales: Mobile sales professionals can access real-time locations. For example, in unfamiliar areas, they can locate themselves as well as customers and prospects, get driving directions and add nearby last-minute appointments to itineraries. Benefits include increased productivity, reduced driving time and increased time spent with customers and prospects.

• Trailer Tracking: Haulage and Logistics companies often operate lorries with detachable load carrying units. The part of the vehicle that drives the load is know as the cab and the load carrying unit is known as the trailer. There are different types of trailer used for different applications, e.g., flat bed, refrigerated, curtain side, box container.

• Transit Tracking: This is the temporary tracking of assets or cargoes from one point to another. Users will ensure that the assets do not stop on route or do a U-Turn in order to ensure the security of the assets.

What is GPS Vehicle Tracking Device?

A GPS tracking unit is a device that uses the Global Positioning System to determine the precise location of a vehicle, person, or other asset to which it is attached and to record the position of the asset at regular intervals. The recorded location data can be stored within the tracking unit, or it may be transmitted to a central location data base, or internet-connected computer, using a cellular (GPRS), radio, or satellite modem embedded in the unit. This allows the asset's location to be displayed against a map backdrop either in real-time or when analysing the track later, using customized software. Such systems are not new; amateur radio operators have been operating their free GPS-based nationwide realtime Automatic Packet Reporting System (APRS) since 1982.

A vehicle tracking system is an electronic device installed in a vehicle to enable the owner or a third party to track the vehicle's location. Most modern vehicle tracking systems use Global Positioning System (GPS) modules for accurate location of the vehicle. Many systems also combine a communications component such as cellular or satellite transmitters to communicate the vehicle’s location to a remote user. Vehicle information can be viewed on electronic maps via the Internet or specialized software.

Vehicle tracking systems are commonly used by fleet operators for fleet management functions such as routing, dispatch, on-board information and security. Other applications include monitoring driving behavior, such as an employer of an employee, or a parent with a teen driver. Vehicle tracking systems are also popular in consumer vehicles as a theft prevention and retrieval device. Police can simply follow the signal emitted by the tracking system and locate the stolen vehicle. When used as a security system, a Vehicle Tracking System may serve as either an addition to or replacement for a traditional Car alarm. The existence of vehicle tracking device then can be used to reduce the insurance cost, because the loss-risk of the vehicle drops significantly.

Vehicle tracking systems are an integrated part of the “layered approach” to vehicle protection, recommended by the National Insurance Crime Bureau (NICB) to prevent motor vehicle theft. This approach recommends four layers of security based on the risk factors pertaining to a specific vehicle. Vehicle Tracking Systems are one such layer, and are described by the NICB as “very effective” in helping police recover stolen vehicles.

Some vehicle tracking systems integrate several security systems, for example by sending an automatic alert to a phone or email if an alarm is triggered or the vehicle is moved without authorization.
