Taxi and auto-rickshaw meters these days have meters that not only calculate distance and fare but also enable the tracking of vehicles. This vehicle tracking is made possible due to a GPS tracking unit that fits inside the meters.
A GPS tracking unit is a navigation device usually carried by a moving vehicle or person that uses GPS.GPS or Global Positioning System works by providing information on the exact location. GPS unit basically determines the movements and location of the device. Recorded data can either be stored or transmitted too. A GPS vehicle tracking system uses the Global Navigation Satellite System (GNSS) network. This network incorporates a range of satellites that use microwave signals that are transmitted to GPS devices to give information on location, vehicle speed, time and direction. These devices can be found in vehicles or smartphones too. The information that broadcasts from the vehicle are things such as location, vehicle speed, direction and so on.
Four things are essential for a GPS tracking system to work effectively: GPS satellite, Vehicle with a GPS tracking device, wireless network, and GPS servers. The GPS tracking device is installed into a vehicle or piece of equipment or asset to gather all sorts of information including speed, idle time, diagnostics, etc. It uses GPS satellites to know the equipment’s position at all times. The gathered information is then stored in the tracking device. Data is further transmitted using a wireless or cellular network through service providers. It travels to a server. The server acts as the cloud that allows one to access information from a computer, tablet or smartphone.
GPS trackers have a GPS module that receives the GPS signal and calculates the coordinates. Data loggers have a large memory that saves all the data. Data pushers contain a modem to transmit the information to a central computer in the form of IP packets. Satellite-based GPS tracking systems operate anywhere on the globe using satellite technology. They do not need a cellular connection.
GPS vehicle tracking solutions are very useful in tracking and monitoring vehicle movement.
