The Ge-T8-E3100 provides the following.
Long range band Used for navigation and avoiding obstacles.
Short range band This is for precision ground mapping, used for planetary navigation.
Used to determine the altitude of the shuttle. It transmits a radar pulse from the bottom of the shuttle, and measures the time it takes for the pulse to return.
This is used by the Kuma during docking and landing maneuvers to provide precise measurements. The system is accurate to 2 cm, and provides rate of closure.
This is a basic inertial navigation system which is used as a vital component of the navigation system and allows the shuttle to perform dead reckoning.
