Global positioning system (GPS) is a technology that is widely used in many parts of the globe today. Initially developed by the U. S. Department of protection, the GPS technology uses about 24 satellites that are orbiting the Earth to calculate the exact position of any object. Transmitted signs from an object reach a satellite after a time delay. The satellite is fitted with a exact clock and it retransmits the obtained signal with a time message. The receiver calculates the time difference and determines the distance to the satellite. The technology takes the help of 3 satellites to calculate the latitude and longitude of the receiver. It uses yet yet another satellite to calculate the altitude.
The GPS technology has been used for many applications in the civilian globe. The vehicle tracking system is one of them. A typical vehicle tracking system consists of the following components:
• A GPS tracking unit is installed in the vehicle. The device captures and stores information at regular intervals. The information can pertain to the location, temperature, door open/close, fuel cutoff, battery status, etc., amongst many others. The extent of the tracking system depends on the capacity of these devices.
• A GPS tracking server gets, stores and produces this information to the user on demand. • The user user interface shows required data in specified formats.
Passive systems gather data that are downloaded later for a batch process. Passive tracking devices are less expensive. energetic systems transmit the data collected in real time for automatic digesting through satellite or cellular systems and inference thereafter. They are more sophisticated and pricey. Many vehicle tracking systems include both energetic and passive methods of operating. Companies that use real time tracking are required to pay a monthly subscription to use the program. The membership can be bought along with the GPS tracking device.
This technology helps the owner of a vehicle or a third party to protect and monitor cellular assets such as cars, buses, ships, bikes, trucks, etc. Their current position can be situated to within a few meters. Fleet management companies can maintain up-to-date records of all fleet activities such as routes, time taken, travel data, mileage, etc. Automatic wi-fi tracking systems download saved data as they near the base station. Thus, there is no requirement for manual downloads. Bus service companies use the GPS technology for adherence to time and direct schedules. events like display of unique concepts and sound stop messages can be triggered working with these vehicle tracking systems.
GPS systems help extensively in vehicle theft prevention and the retrieval of the vehicle. In inclusion to being able to locate the position of the vehicle, some systems allow the engine and door to get blocked by making use of remote control. Vehicle tracking systems are used extensively by field sales personnel for food providey and vehicle rental companies to improve and optimize their business expenditure. Companies and individuals use the GPS technology to track valuable assets in motion. They can be used for covert surveillance operations.
The new GPS vehicle tracking systems deliver data via the web in a user friendly manner. They are programmed to deliver pertinent data in various languages.
