Abstract
A velocity estimation method and system is disclosed. The method may include receiving a location signal indicative of a location of the machine and estimating the velocity of the machine based on a change in the location of the machine over a period of time. The method may further include determining a loss of the location signal, detecting a traction device speed of the machine, and selectively estimating the velocity of the machine based on the traction device speed when the location signal is determined to be lost.
