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.
