|Welcome to the Fall 2021 issue of NAVIGATION. In this issue, we feature articles on a wide range of topics from R-Mode, a proposed new maritime PNT backup system, to new algorithms for improving GNSS integrity in a variety of applications, to positioning using the Doppler shift of signals from a constellation of low-Earth-orbiting satellites. It is articles like these, from authors around the globe reporting on their frontline research and benefitting from our dedicated group of associate editors and reviewers, that have made NAVIGATION a leading journal for the PNT community. In fact, I am proud to announce that NAVIGATION has recorded its sixth consecutive year of growth of its journal impact factor and is now 2.1! Authors can further promote their research through video abstracts hosted on the ION website. The latest ones 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, including one on the U.S. Government Accountability Office’s report on defense navigation capabilities, are also documented below.
