WebTools. The airspeed indicator ( ASI) or airspeed gauge is a flight instrument indicating the airspeed of an aircraft in kilometers per hour (km/h), knots (kn), miles per hour (MPH) and/or meters per second (m/s). The recommendation by ICAO is to use km/h, however knots is currently the most used unit. The ASI measures the pressure differential ... Weba mechanical frame, called the Navigation Base (or Navbase), to rigidly connect the optical device and, in the LM, the rendezvous radar to the IMU. This included use of early "star trackers", gyroscopes, and accelerometers. JPL has a really good explanation of how spacecraft determine their location and speed.
