GPS receivers utilizing two or maybe more antennae mounted individually and Mixing the info with the inertial motion unit (IMU) can now obtain 0.02° in heading accuracy and have startup occasions in seconds in lieu of hours for gyrocompass methods. The devices accurately identify the positions (latitudes, longitudes and altitude) with the antennae about the Earth, from which the cardinal Instructions can be calculated.
