【讲座信息】

  当下，有三个“支柱（pillars）”因素决定着导航技术的性能或实用性，即成本、精度和连续性。导航是一门长盛不衰的技术，数千年来，持续吸引着人们前赴后继地研究。毫无疑问，全球导航卫星系统（Global Navigation Satellite System, GNSS）主导着目前的定位导航市场。GNSS除了能够提供全球性的服务外，还满足了上述与成本、精度有关的两种“支柱”条件。换句话说，它能以较低成本的代价，提供各种不同精度要求范围内的导航定位信息。另外，该技术还可以满足高便携性和低功耗的需求，非常适合与其他各类传感器、通信链接以及数据库进行融合。

  尽管GNSS优势众多，但它并非适用于任何环境下的导航任务，从而导致其无法满足“连续性”的“支柱”要求。因此，为了进一步地发展导航技术，急需发展一种替代型的导航定位系统。目前，导航系统的市场也在朝着精确的、连续的、易购的方向稳步发展。毋庸置疑，在系统成本和体积的制约下，汽车、便携设备（如智能手机）、自动控制系统（如自动驾驶、无人机和农业机械系统）的制造商得以研究和开发下一代低成本、小型化的导航系统，从而满足快速发展的自动驾驶车辆及位置服务市场的需求。此次报告将着眼于自动驾驶车辆，介绍其所用传感器的最新情况及未来发展趋势，其中包括传感器的可能性、限制性以及各种不同的设计方案。此次报告的重点，还将集中于如何利用传感器和相关技术，实现随处的、全天时的、全天候的轻量型自动驾驶车辆导航系统。最后，报告将通过不同的实验/应用，演示一些目前已开发的及未来可能出现的导航系统的精度性能。

There are three ‘pillars’ that define the performance or usefulness of a navigation technologies – cost, accuracy, and continuity. Navigation is a field that has been fascinating humankind for thousands of years and these pillars have been evolving with new technological advancements.  The current market in positioning and navigation is clearly dominated by GNSS. Besides being globally available, it meets two important pillars: accuracy and cost by providing the whole range of navigation accuracies at very low cost. It is also highly portable, has low power consumption, and is well suited for integration with other sensors, communication links, and databases.

At this point in the development of navigation technology, the need for alternative positioning systems only arises because GNSS does meet the continuity pillar as it does not work in all environments. Furthermore, there has been a constant market push to develop navigation systems that are accurate, continuous and easy to afford. Needless to say, that cost, and space constraints are currently driving manufacturers of cars, portable devices (e.g. smartphones), and autonomous systems (e.g. self-driving, drones and agriculture machine systems) systems to investigate and develop next generation of low cost and small size navigation systems to meet the fast-growing autonomous vehicles and location services market demands. This presentation will provide a state of the art and future trends of sensors used for navigation of autonomous vehicles: possibilities, limitations and various design approaches.  Emphasis will be on sensors and technologies that can navigate autonomous vehicles everywhere and at any time independent of weather and light conditions. Some of the current developed and possible future system’s accuracy performance will be demonstrated through different implementations/applications.
