IEEE ION Position Location and Navigation Symposium PLANS and perhaps safety of life applications where low cost is a necessity and relatively precise positioning for availability and integrity purposes is required For safety critical and high precision applications such as vehicle automation PPP can be used alongside or in combination with RTK for robustness and independence with low cost hardware Such a parallel and collaborative approach would require a hybrid user processing engine and robust state space corrections from a variety of local regional and global sources as we are seeing from some current geodetic hardware based commercial services Near future trends should also include more lowcost multi sensor integration with PPP augmentation Optimized navigation algorithms and efficient user processing engines will be a priority as the capabilities of low cost equipment continue to increase and low cost integrated sensor solutions are required for mass market applications Analogous to meter level point position GNSS lower hardware costs should drive markets to volume sales PPP like correction services and GNSSbased multi sensor integration into more navigation technology solutions for various industry and consumer applications MORE ONLINE SAVE THE DATE Clearly the future of PPP continues to be bright www ion org plans 2018 April 23 26 2018 Hyatt Regency Monterey Monterey California 48 GPS WORLD WWW GPSWORLD COM MARCH 2018 SUNIL BISNATH is an associate professor in the Department of Earth and Space Science and Engineering at York University Toronto Canada For over twenty years he has been actively researching GNSS processing algorithms for a wide variety of positioning and navigation applications JOHN AGGREY is a Ph D candidate in the Department of Earth and Space Science and Engineering at York University He completed his B Sc in geomatics at Kwame Nkrumah University of Science and Technology Ghana and his M Sc at York University His research currently focuses on the design development and testing of GNSS PPP software including functional stochastic and error mitigation models GARRETT SEEPERSAD is a navigation software design engineer for highprecision GNSS at u blox AG and concurrently is completing his Ph D in the Department of Earth and Space Science and Engineering at York University His Ph D research focuses on GNSS PPP and ambiguity resolution He completed his B Sc in geomatics at the University of the West Indies in Trinidad and Tobago He holds an M Sc degree in the same field from York University MANINDER GILL is a geomatics designer at NovAtel Inc and concurrently is completing his M Sc in the Department of Earth and Space Science and Engineering at York University His M Sc research focuses on GNSS PPP and improving positioning accuracy for low cost GNSS receivers He holds a B Eng degree in geomatics engineering from York University Further Reading For references related to this article and bonus text go to gpsworld com and click on More in the navigation bar then on Innovation
