To attain the 10-centimeter accuracy required for autonomous vehicle positioning within urban multipath propagation conditions, there is a need for a significant upgrade in GNSS antenna performance, Technical Director Oliver Leisten writes in the latest edition of GPS World. The autonomous vehicle application demands excellent antenna performance together with exploitation of the full set of GNSS multi-frequency and multi-constellation system advances to deliver this performance paradigm in the most severe of real-world use scenarios.
