Precise positioning down to the centimeter level underpins a new wave of IoT and connected applications. These range from consumer devices to advanced driver assistance systems (ADAS) and countless applications in professional markets from logistics to micromobility management in smart cities, as well as mining and agriculture. The challenge here is that precision is hard to achieve and relies on a blend of components, devices, cellular and satellite connectivity plus mastery of complex techniques to eliminate errors and enhance accuracy.
Although GNSS offers ubiquitous coverage over the surface of the planet, there can be situations where signals are attenuated by heavy vegetation or obstructed completely inside tunnels or partially by tall buildings in dense urban canyons.
