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.

全球定位系统（GPS）以及现在更普遍的全球导航卫星系统（GNSS）是几米级室外定位和导航的事实上的国际标准。 对全球导航卫星系统，特别是高性能全球导航卫星系统接收器和天线进行了许多增强，以提高地方、区域或全球性能（精确度、准确度、完整性、可用性等）。 在这些增强技术中，一种称为“精确单点定位”或“PPP”的测量处理技术在全球一级大大推进了这些目标，同时最大限度地减少了对地面基础设施的要求。 我在约克大学的研究团队在过去十年中一直致力于改进PPP，拟议的研究计划现在准备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以前的两个DG的GNSS PPP研究进展传播到新一代cm中，该中心将继续致力于开发全球导航卫星系统级的全球导航卫星系统技术，并将这一专门知识与新型低成本消费级全球导航卫星系统接收器和天线以及其他导航传感器相结合，研究和开发以全球导航卫星系统为基础的精确（分米至厘米级）、低成本、稳健的导航解决方案。 其结果将是将昂贵的精确卫星定位从少数商业和科学用户扩展到测绘;陆地/空中/海面（半）自动车辆/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;并最终实现无处不在的定位，即在任何地方、任何条件下不受限制地知道自己位置的能力。 2)将测地硬件的全球导航卫星系统PPP初始收敛周期从10分钟减少到几十秒，并尽量减少先验信息。 3)在消费级低成本（全球导航卫星系统芯片组）和超低成本（移动的电话和平板电脑）硬件中实施、加强和商业化单频和双频全球导航卫星系统PPP。 4)将GNSS与PPP和下一代低成本导航传感器集成，以提供导航鲁棒性、精确性、完整性、抗干扰和防欺骗。 5)集成GNSS PPP和高清（HD）测绘导航。
