Nowadays, multi-Global Navigation Satellite Systems (GNSS) have been developed and widely used, including US's GPS, Russia's GLONASS, China's BeiDou and EU's Galileo as well as regional systems, such as Japan's QZSS and India's IRNSS. The International Conference on GNSS+: Advances, Opportunities and Challenges (ICG+2016) will be held on July 27-30, 2016, Shanghai, China. The ICG+2016 aims to provide a platform for GNSS scientists and engineers to communicate and exchange in theory, methods, technologies, applications and future challenges. The ICG+2016 is open to all scientists who may have the latest results and developments in BDS/GNSS+, including constellations, signals, orbit, receiver, positioning/navigation/timing theory, algorithms, models and applications in engineering and Earth science as well as combining multi-sensors. Manuscripts on new advances in Multi-GNSS and other regional systems, compatibility, interoperability and new applications are also welcomed. 
The ICG+2016 is jointly sponsored by the International Association of Geodesy (IAG), International Association of Chinese Professionals in Global Positioning Systems (CPGPS), Shanghai Astronomical Observatory, CAS and Shanghai Jiao Tong University, China.
