simultaneous localization and mapping (automotive) (SLAM)

For the development of autonomous vehicles, the GPS system plays a crucial role because it supports location and vehicle movement or location tracking.

Since the accuracy of GPS is limited to a few meters, and satellite reception is affected by mountains or high-rise buildings, autonomous driving technology cannot rely solely on the GPS system, but must also use techniques that work in situations where no GPS signal is available.

Simultaneous Localization and Mapping (SLAM) is one such technique used to calculate the location of the motor vehicle in unknown environments, accurate to within a few centimeters without a satellite connection. The SLAM method uses tracking in the six degrees of freedom right/left, up/down and forward/backward to determine the position.
