Precise GNSS Positioning and Navigation: Methods, Challenges, and Applications

Dear Colleagues,

The Global Navigation Satellite System (GNSS) can provide users with high-precision positioning information continuously and benefits all walks of life, e.g., unmanned driving, urban navigation, deformation monitoring, etc. The important scientific research and application value of GNSS have prompted many countries and regions to develop GNSS technologies. GNSS core positioning technologies, such as PPP and RTK, can provide decimeter-level or even centimeter-level positioning accuracy in open environments. However, active GNSS positioning technologies are susceptible to complex conditions including canyon environment, low-cost receiver, and multi-GNSS situations, and sometimes cannot provide accurate, continuous, and reliable positioning information. The diversification of GNSS systems and constellations, receiver types, and observation environments puts forward higher requirements for technology and algorithms to maintain high-precision positioning and navigation services. Advanced algorithms are the key to solving GNSS practical application problems and expanding the scope of GNSS applications.

This Special Issue aims at studies covering improved methods and the latest challenges in precise GNSS positioning and navigation, especially under complex conditions for various research investigations as well as a range of practical applications. We encourage both theoretical and applied research contributions to the GNSS high-precision technology in all disciplines. Topics may cover anything from precise muti-GNSS positioning algorithms, and GNSS data processing to more comprehensive targets and scales. Therefore, new algorithms for high-precision positioning and navigation, GNSS receivers, software development for data collection and processing, and their applications in various fields are welcome.

Articles may address, but are not limited, to the following topics:

• GNSS data processing methods
• GNSS applications
• Precise GNSS positioning and navigation
• Theory, model, and method for processing the GNSS errors
• Multi-GNSS positioning technologies
• Positioning and navigation methods under challenging environments
• Low-cost GNSS positioning and navigation
