Which mechanism causes an aircraft navigation system's bias due to Earth rotation?

💡 Explanation

The Sagnac effect generates interference patterns correlated to rotation because light circumnavigating an enclosed area experiences a path length difference related to rotation, thus influencing navigation; therefore, it biases positional accuracy rather than Doppler induced frequency shifts.
