Navigator Notes: Editorial Highlights from the Editor-in-Chief

Richard B. Langley

Abstract: Welcome to the Spring 2022 issue of NAVIGATION – our first issue since transitioning to an open access journal at the beginning of the year. As I mentioned in “Navigator Notes” in the Winter 2021 issue, all journal articles from now on will be available for download without charge. And Institute of Navigation members will be able to download complete issues. Consult the ION website at for details. In this issue, we again feature articles on a wide range of topics including detection of GPS satellite oscillator anomalies, vision localization, and GNSS spoofing. We are also featuring an article on the design of a lunar navigation satellite system as well as a comprehensive article on how the Wide Area Augmentation System monitors the state of the ionosphere to protect users from ionospheric disturbances. ION will continue promoting the research of journal authors through video abstracts hosted on the ION website. In fact, a video abstract will become compulsory for publishing in NAVIGATION. The latest video abstracts are documented below. ION also engages with the PNT community, through its webinar series, to highlight current topics of interest to the community. The most recent webinars are also documented below and we announce the ION 2021 Samuel M. Burka Award winner.
