The Global Positioning System (GPS) has become the preeminent method of outdoor positioning and navigation. From GPS, the global community is developing multiple satellite-based navigation systems or Global Navigation Satellite Systems (GNSS). Research has focused on improvement of receiver (and antenna) design and data processing algorithms, which have driven unpredicted application growth and diversity. Most contemporary high-precision algorithm development has focused on applications spanning localized areas (e.g., few tens of kilometres), utilizing costly GNSS infrastructure, particularly reference stations, to reduce systematic measurement errors. The fundamental goal of the proposed research program is to improve the Precise Point Positioning (PPP) positioning and navigation measurement processing algorithms to perform few centimetre-level positioning anywhere on or above the Earth without the necessity of local reference stations and long observation periods. That is, to develop PPP technology to perform like Real-Time Kinematic (RTK) without its significant limitations. I propose to build on my team's previous and current novel research. There are three aims proposed in the research plan: 1) the development of a innovative multi-GNSS PPP user processor, 2) the development of robust PPP ambiguity resolution and validation approaches, and 3) the development of a PPP user algorithm capable of initial convergence in tens of seconds. Research results will be used, through the dissemination of algorithms and methods via publications, technology transfers and commercialization, to modernize precise positioning and navigation, which will increase productivity and improve safety-of-life applications across numerous economic sectors in Canada and abroad, and advance scientific applications.

全球定位系统（GPS）已成为户外定位和导航的卓越方法。 从全球定位系统，全球社会正在开发多个卫星导航系统或全球导航卫星系统（GNSS）。 研究集中在接收器（和天线）设计和数据处理算法的改进上，这推动了不可预测的应用增长和多样性。 大多数当代高精度算法开发集中在跨越局部区域的应用（例如，这一技术的目的是利用昂贵的全球导航卫星系统基础设施，特别是基准台站，减少系统测量误差。 拟议的研究计划的基本目标是改进精密单点定位（PPP）定位和导航测量处理算法，以在地球上或地球上方的任何地方执行几厘米级定位，而不需要本地参考站和长时间的观测。 也就是说，开发PPP技术，使其像实时动态（RTK）一样执行，而没有其显著的限制。 我建议以我的团队以前和现在的小说研究为基础。 该研究计划提出了三个目标：1）开发创新的多GNSS PPP用户处理器，2）开发鲁棒的PPP模糊度解算和验证方法，以及3）开发能够在数十秒内初始收敛的PPP用户算法。 研究成果将通过出版物、技术转让和商业化传播算法和方法，用于精确定位和导航的现代化，这将提高生产力，改善加拿大和国外众多经济部门的生命安全应用，并推动科学应用。
