With the growing number of IoT devices (50 billion expected by 2020), the development of next-generation IoT services and applications must include more precise positioning information and higher availability. Such capabilities are crucial for positioning and navigation of Unmanned Aerial Vehicles (UAV) in confined environments, connecting self-driving cars in intelligent transportation systems, and geo-referencing of smartphones for mobile mapping. Current precise systems are based on high-grade global navigation satellite systems (GNSS) and inertial navigation systems (INS). However, these are large in size and too expensive for most IoT mobile devices that are equipped with low-cost GNSS and inertial sensors due to space and cost constraints. This project is a joint submission under the international collaborations program with the Ministry of Science and Technology (MOST) of Taiwan with academic and industrial collaborators in both countries. It aims at developing a new integrated GNSS/INS system to enable high availability precise positioning using low-cost GNSS and MEMS inertial sensors for IoT mobile devices. A novel GNSS augmentation system architecture will be developed to facilitate precise positioning insensitive to precision augmentation signal outages. Combined with new inter-aiding and error mitigation methodologies for GNSS and inertial sensors, high availability continuous navigation solutions become obtainable in adverse environments. Such a system can be applied as an embedded solution for a wide range of IoT mobile devices from smartphones, tablets, and UAVs, to emerging driverless cars.

随着物联网设备的越来越多（预计到2020年），下一代物联网服务和应用程序的开发必须包括更精确的定位信息和更高的可用性。此类功能对于在狭窄的环境中无人机（UAV）的定位和导航至关重要，连接智能运输系统中的自动驾驶汽车以及对智能手机进行移动映射的地理参考。当前的精确系统基于高级全球导航卫星系统（GNSS）和惯性导航系统（INS）。但是，由于空间和成本限制，大多数配备有低成本GNSS和惯性传感器的物联网移动设备的尺寸很大，而且太昂贵了。该项目是与台湾科学技术部（大多数）与两国的学术和工业合作者的国际合作计划共同提交的。它旨在开发一种新的集成GNS/INS系统，以使用与物联网移动设备的低成本GNS和MEM惯性传感器进行高可用性精确定位。将开发出一种新型的GNSS增强系统架构，以促进精确定位对精确增强信号中断的不敏感。结合GNSS和惯性传感器的新的相互作用和误差缓解方法，高可用性连续导航解决方案在不利环境中可获得。这样的系统可以用作嵌入式解决方案，用于从智能手机，平板电脑和无人机到新兴无人驾驶汽车的各种物联网移动设备。
