Precision GNSS: Technology Advances and Applications for Navigation and Mapping



The Global Navigation Satellite Systems (GNSS) have become an indispensable component for a wide range of applications. With rapid advances in GNSS system development which currently includes four operational systems and various regional augmentation systems, high accuracy is increasingly demanded by many emerging applications. For examples, within-lane autonomous vehicle control requires dm or better positioning accuracy while dm accuracy is also demanded for smartphone-based navigation and mapping. Although high accuracy has been widely demonstrated, the use of low-cost GNSS receivers in mass-market applications present various challenges in order to achieve high accuracy with stringent requirements on system availability and integrity. This workshop will seek contributions that are addressing the related challenges. They can be research progress on the development of new concept, models, algorithms and systems for precise GNSS positioning (PPP, PPP-RTK, LEO etc) and integrated navigation systems (GNSS, INS, Vision etc), as well as novel applications to navigation and mapping including application system design, implementation, prototype, product and testing results.
The workshop will be part of the ISPRS Geospatial Week 2023 and is hosted by the Arab Academy for Science, Technology, and Maritime Transport (AASTMT) in parallel with several related geospatial workshops.
