RECALIBRATING AN INERTIAL NAVIGATION SYSTEM |
摘要 |
<p>A device may include a radio signal receiver, and an inertial navigation system. Additionally, the device may include a processor to determine that the inertial navigation system has been initiated, monitor a radio signal associated with a mobile network received at the radio signal receiver, and determine a channel impulse response (CIR) based on the radio signal. The device may also monitor a Doppler spread of the radio signal based on the CIR in a time domain until a zero Doppler spread is identified. The device may recalibrate the inertial navigation system based on the zero Doppler spread.</p> |
