Gps tracking
A GPS tracking system uses either GPS and some radio technology (usually a modem) to automatically track and record a vehicle's, person's, or pet's field activities. Position is determined using GPS and recorded by modules attached to each vehicle.
The data could be transmitted to a central, internet-connected computer using radio communications, usually a GSM/GPRS cellular modem. Data can then be analyzed and reports can be downloaded in real-time to your computer using either web browser based tools or customized software.
