Special Session Topics

The Chinese satellite navigation system Beidou is now a fully operational worldwide GNSS with 35 Phase III satellites now in orbit. This special session will feature invited and contributed presentations on all aspects of current and new Beidou 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, Beidou/GNSS Interference detection, inter-satellite link technology, messaging systems, and new Beidou/GNSS applications.

COSMIC/FORMOSAT 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. This special session will feature invited presentations and contributed work on all aspects of this exemplifying project and future outlook of the next generation capabilities.
Dr. Loren Chang, National Central University, Taiwan

Japan’s Quasi-Zenith Satellite System (QZSS) became operational in 2018. Four future satellites are being planned to provide independent navigation capabilities over Japan. This session will have presentations from the government, contractors, universities, and industries. Attending the session, you will be fully informed about 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.

If you have not used the Abstract Management Portal before, click “Create My Account”. Once signed in, click on ION Pacific PNT 2021 and complete the form.

Abstracts should describe objectives, anticipated or actual results, conclusions, any key innovative steps and the significance of your work.

Authors will be provided with an author’s kit in early December, which will contain both in-person and virtual presentation instructions, and publication guidelines.

Virtual presentations will be made available to authors who have passed peer review that are unable to travel to Hawaii to present in person due to U.S. State Department entry restrictions, and who also meet all other virtual presentation requirements.

All authors and session chairs will be required to pay registration fees.

Final Manuscripts

Completed manuscripts must be uploaded to the Abstract Management Portal (AMP) by February 12, 2021. Manuscripts will be designated as a primary paper, or as an alternate paper, in the onsite program based on the Session Chairs’ peer review of the full manuscripts.

Manuscripts will be peer reviewed once (note that there will be no secondary review). Papers not representative of the original abstract submitted will not be included in the conference proceedings regardless of whether or not they were presented at the conference; and this may affect the acceptance of future abstracts by the author. While full manuscripts are required for peer review by February 12,
corrected/updated manuscripts will be accepted through April 30, 2021.

To be included in the conference proceedings, final manuscripts must meet review requirements; an author must present at the conference as scheduled in the conference program and pay the conference registration fee.

Exceptional manuscripts will be considered for Best Paper Awards.

Complimentary online access to papers will be provided to all eligible conference registrants through June 30, 2021. Eligible conference registrants will be able to download the proceedings following the conference.

Journal Publication

Authors of appropriate papers are encouraged to submit papers for possible publication in the ION’s archival journal, NAVIGATION, indexed by Thomson Reuters. Papers may be submitted online at
