Inertial Navigation System


We just learned about the Reaction Control System.

Another part of rocket science is an Inertial Navigation System, or just INS for short.

We've learned that accelerometers, gyroscopes and magnetometers are all sensors that can tell a rocket where it is going.
An INS is a computer that is hooked up to different sensors like these, and it steers the rocket the right way based on what the sensors tell it.
