ABSTRACT:
An extremely sensitive accelerometer suitable for use in extreme temperatures such as those encountered during space travel is formed by levitating a magnet in a box or sphere composed of diamagnetic material such as pyrolytic carbon, and a means for measuring the position of the magnet within the enclosure is provided so that over time, the position of the magnet can be monitored. Knowing the mass of the suspended magnet, the displacement over time of the magnetic can be used to calculate acceleration, which can then be used to determine position of a space vehicle.
