What is the difference between a real-time and a passive vehicle tracking system?

2011-6-14 GPS tracking receivers of all kinds capture signals from satellites orbiting the planet and determine the location of the receiver based on those readings. The user follows the object’s movements on personal computer. Real-time, also known as active, GPS tracking systems tell where a vehicle is, in real time. Passive vehicle tracking devices record travel history and the user can later download the data and analyze it at a time when it is convenient to them.
