Abstract: Autonomous vehicle applications, such as assisted driving, collision avoidance or platooning, demand precise, reliable and secure localization in harsh environments such as tunnels and urban areas. In order to face these positioning challenges, multiple navigation technologies have to be fused. These technologies are typically based on Global Navigation Satellite Systems (GNSS), radar, camera, sensors and signals of opportunity. Indeed, the exploitation of cellular communications for positioning is of special interest due to the advanced physical features of fourth generation (4G) and fifth generation (5G) networks. The objective of this work is to assess the performance limits of hybrid GNSS and LTE solutions, based on assisted or opportunistic approaches. For this purpose, a software tool is presented to evaluate different hybrid scenarios, by using field GNSS and simulate LTE observables. The assisted LTE approach is shown to outperform the opportunistic approach, and the hybrid solutions achieve a position accuracy around 3 meters and a position fix of 100% in urban and road scenarios. Future work is still necessary to fulfil the location requirements of autonomous vehicle applications.
