Special Session Topics
BeiDou
The Chinese satellite navigation system, BeiDou (BDS), is now a fully operational worldwide GNSS with more than 30 satellites in orbit. This special session will feature invited and contributed presentations on all aspects of current and new BDS systems and application developments: new BDS signal designs and receiver development, BDS signal-in-space quality monitoring and assessment, interoperable space service volume for autonomous orbital determination, BDS augmentation system, BDS/GNSS interference detection, inter-satellite link technology, message systems, and new BDS/GNSS services/applications.
Chairs:
Dr. Zheng Yao, Tsinghua University
Dr. Hui Liu, Wuhan University
COSMIC/FORMOSAT
COSMIC/FORMOSAT-3 is a constellation of six micro-satellites launched one decade ago through a partnership between Taiwan and the US. These extremely cost-effective LEO satellites rely on occultation measurements of GPS signals to infer atmospheric profiles to improve weather forecasting, climate modeling, and ionosphere and space weather monitoring. The resounding success of the project led to a follow-on mission, COSMIC-2/FORMOSAT-7, launched in 2019. Additionally, FORMOSAT-7R Triton was launched in 2023 to use GNSS Reflectometry to characterize ocean surface roughness from which sea surface winds can be inferred. This special session will feature invited presentations and contributed work on all aspects of this exemplifying project and outlook of the next generation capabilities.
Chairs:
Dr. Loren Chang, National Central University
Dr. Janet Zeng, University Corporation for Atmospheric Research
QZSS
Japan’s Quasi-Zenith Satellite System (QZSS) became operational in 2018. Four satellites are currently operational with an additional seven planned to provide independent navigation capabilities over Japan and the Asia Pacific region. This session will have presentations from government, contractors, universities, and industries. The session will fully inform on the QZSS regional satellite navigation program, including the latest QZSS program status, launch schedule of satellites, navigation performance, payload design/characteristics, receiver development, technical validation results, and application development activities.
