Navigation

The ISS must be able to know exactly where it is in space, where other objects are and how to go from one point in space to another, especially during reboosting.
To know where it is and how fast it is moving, the ISS uses both U.S. and Russian global positioning systems (GPS). To know which way it is pointing (its attitude), the ISS has several gyroscopes.
The combination of all this information will help the ISS move from one point to another in space.
Moreover, the Russian navigation system uses sighting on the stars, sun and Earth's horizon for navigation.
