The invention proposes a system which includes various devices (inertial devices, BA correction device, alignment signaling device) and an ensemble of sensors that allows a novel BA-correction. This allows a reduction in the BA frequency and a gain in efficiency.
Wireless communications in the future will be using high frequencies up to the mmwave spectrum (say >6GHz, typ. 10GHz or higher such as 28GHz as for mmWave 5G, or 60GHz as for WiGig system) as less crowded than lower frequencies. The mmwave attenuates fast and, to capture information, is used the technique of beamforming (generation of a directional preferred gain).
In the particular application of autonomous driving, this technology can be used but the beam-alignment (required for this type of wireless communication) is perturbed since the car is moving.
