Passive GPS

Passive GPS devices store GPS location, speed, heading that can be quickly downloaded from the device onto your computer. The device is sometimes triggered by an event such as key on/off, door open/closed. Passive GPS is commonly used with fleet management and vehicle tracking where GPS data only needs to be harvested once in awhile rather than in real-time. Once the vehicle returns to a predetermined point, the device is removed and the data downloaded to a computer for evaluation. On the other hand, active GPS devices also collect the same information but usually transmit the data in real-time via cellular or satellite networks to a computer or data center for evaluation.
