As other people have mentioned, this isn&#x27;t so much a compass, as am accelerometer. With it you can use dead reckoning to infer your position. One of the problems with current system (for example MEMS accelerometers), is that any small offset at zero acceleration will cause position errors which accumulate quadratically with time. In theory at least, these quantum accelerometers provide a accurate, stable measure of the absolute acceleration.
