High-Precision GNSS Antennas for Automotive Applications

Connected vehicles and autonomous driving are key factors driving growth in the automotive market, and Global Navigation Satellite System (GNSS) is a primary wireless protocol adopted to support emergency, navigation, and positioning services. High-precision GNSS is now transforming these systems thanks to its centimeter/decimeter level reliability and accuracy to assist autonomous services. Additionally, A-GNSS (Augmented GNSS) used in conjunction with GNSS helps quicken the start-up performance for positioning.

Antennas play a vital role in making or breaking wireless communication. Diverse types of antennas for GNSS and A-GNSS are employed throughout the body of an automobile to work with the GNSS and A-GNSS modules and chipsets. This presentation will detail GNSS bands for high-precision GNSS applications, RF (Radio Frequency) receiver requirements, available high-precision GNSS and A-GNSS antennas, ways to integrate antennas into automotive vehicles, and factors to determine antenna performance.
