With the development of Connected Vehicle, various of on-board applications and functions rely on stable, reliable and fast-response wireless connections furtherly, making it more urgent and widespread for vehicles to be equipped with relevant antenna systems such as positioning and communication. There are many types of vehicle antenna systems, together with a wide range of installation locations and a complex electronic environment which brings a huge challenges to the development of antenna manufacturers and the matching of automobile OEMs. In order to carry out the R&D, matching and testing of the vehicle antenna system better, various parties have proposed a multi-dimensional test and evaluation methods, but there is still a lack of horizontal evaluation between them. This paper analyses the requirements of automotive antenna system evaluation, sorts out and compares the technical paths of various common solutions, summarizes the characteristics and differences of various solutions, and provides a research foundation for further optimizing the vehicle-level antenna system test and evaluation program.

With the rapid development of the automotive industry, vehicles are equipped with a variety of system functions. The realization of many of these functions depends on the stable, safe, and reliable positioning and timing information of the bottom layer. Vehicle-mounted satellite positioning systems are an important way for vehicles to obtain absolute positions and have been widely employed in other industries. However, the automotive industry has its special requirements, such as high positioning accuracy and confidence, extremely harsh vehicle regulations, reliability, and high safety, all of which need to be tested and evaluated on vehicle-mounted satellite positioning systems. By studying and putting forward the evaluation scheme for the vehicle-mounted satellite positioning system, this paper further ensures the accuracy, reliability, and stability of the time-space information provided by the system and supports the development of the automotive industry.
