Next-generation, robust, precise, satellite-driven positioning and navigation

全球定位系统（GPS）和现在更普遍的全球导航卫星系统（GNSS）是在几米高度进行户外定位和导航的事实上的国际标准。已经对GNSS，特别是高性能GNSS接收器和天线进行了许多增强，以提高本地、区域或全球性能（精度、准确性、完整性、可用性等）。在这些增强技术中，一种称为“精确点定位”或“PPP”的测量处理技术在全球范围内显著推进了这些目标，同时最大限度地减少了对地面基础设施的需求。我在约克大学的研究团队在过去的十年里一直致力于改进PPP，现在提议的研究计划已经准备好将这些发展扩展到更广泛的定位和导航应用中，以提高定位精度、位置可用性和信息完整性。******该研究计划建议将我的前两个dg的GNSS PPP研究进展推广到新一代厘米级GNSS技术中，并将这种专业知识与新的低成本，消费级GNSS接收器和天线以及其他导航传感器相结合，以研究和开发基于GNSS的精确（dm- cm级），低成本，强大的导航解决方案。其结果将是，昂贵的精确卫星定位将从少数商业和科学用户显著扩大到测绘；陆地/空中/海面（半）自主车辆/机器控制；行人导航;游戏/新应用；城市/受限环境；室外/室内导航;最终，无处不在的定位——在任何地方、任何条件下都能不受限制地知道自己的位置。******短期目标：1)完成通用GNSS PPP引擎的开发。2)在先验信息最小化的情况下，将大地测量硬件的GNSS PPP初始收敛周期从10分钟缩短到数十秒。3)在消费级低成本（GNSS芯片组）和超低成本（手机和平板电脑）硬件中实施、提升和商业化GNSS单频和双频PPP。4)将GNSS与PPP和下一代低成本导航传感器集成，提供导航鲁棒性、精度、完整性、抗干扰和抗欺骗。5)整合GNSS PPP和高清地图导航。

The Global Positioning System (GPS) and now more generally, Global Navigation Satellite Systems (GNSS) are the de facto international standard for outdoor positioning and navigation at the few-metre-level. Numerous augmentations have been made to GNSS, especially high-performance GNSS receivers and antennas, to allow for improved local, regional or global performance (precision, accuracy, integrity, availability, etc.). Of these augmentations, a measurement processing technique known as “Precise Point Positioning” or “PPP” has significantly advance these goals at the global level, while minimizing terrestrial infrastructure requirements. My research team at York University has been working on improvements to PPP over the last decade, and the proposed research program is now ready to expand these developments into a much wider range of positioning and navigation applications for improved location accuracy, position availability and information integrity.******The research program proposes to propagate the GNSS PPP research developments from my previous two DGs into a new generation of cm-level GNSS technology, and to combine this expertise with new low-cost, consumer grade GNSS receivers and antennas, as well as other navigation sensors, to research and develop precise (dm-to-cm-level), low-cost, robust navigation solutions rooted in GNSS. The result will be a significant widening of costly precise satellite-based positioning from a handful of commercial and scientific users to mapping; land/air/sea surface (semi-)autonomous vehicles / machine control; pedestrian navigation; gamming / new applications; urban / constrained environments; outdoor/indoor navigation; and, eventually, ubiquitous positioning the ability to know one's location anywhere, under any conditions without constraints.******Short-term objectives are: 1) Complete development of universal GNSS PPP engine. 2) Reduce GNSS PPP initial convergence period for geodetic hardware down from ten minutes to tens of seconds with minimized a priori information. 3) Implement, enhance and commercialize single- and dual-frequency GNSS PPP in consumer-grade low-cost (GNSS chip sets) and ultra-low-cost (mobile phones and tablets) hardware. 4) Integrate GNSS with PPP, and the next-generation, low-cost navigation sensors to provide navigation robustness, precision, integrity, anti-jamming, and anti-spoofing. 5) Integrate GNSS PPP and high-definition (HD) mapping navigation.
