Real-Time GPS Tracker:
Also known as a live tracker, real-time GPS tracking systems record a variety of information related to position and travel, transmitting that data using telecommunications technology. This allows users to have remote access to where a vehicle is located, and everywhere that vehicle has traveled. Real-time GPS trackers are often used for auto-theft prevention, law enforcement surveillance and business fleet management.
Also referred to as a sampling rate, the refresh rate is the frequency of locational positions that are updated and stored by a GPS receiver. Occasionally thought of as "bread crumb trails" or "pings", the refresh rate can vary on the type of GPS tracking device the user is operating. For example, GPS Tracking Key has a refresh rate of every second, while the SilverCloud GPS refresh rate depends on the data plan the user selected (3 seconds-5 minutes).
