"Tracking" is the term we use when talking about an Asset that you want to know where it is at any point in time.
Tracking information is sent from a Locator unit attached to the Asset. Tracking information consists of Latitude and Longitude, current speed, and sometimes odometer values (calculated within the Tracking unit based on calculations from latitude and longitude movement).
Some units support the sending and control of Inputs and Outputs for additional control and monitoring of the Asset.
