Signal to jammer ratio - how to make gps jammer military

The Royal Institute of Navigation (RIN) has issued a call for papers for the Navigation 2021 conference. The conference, which as of now will be held virtually Nov. 15-18, 2021, will bring together experts from industry, research institutions, government agencies and investors whose primary goal is to work together for a more navigable world, RIN said. Conference themes will include PNT systems and technology, robust PNT, PNT applications, animal and human navigation, and navigation in society. The November 2021 event will unite two established conferences: the International Navigation Conference and the European Navigation Conference. RIN is accepting papers in the following categories: Peer-reviewed: Abstracts and, if accepted, papers will be peer reviewed and published to be indexed and searchable. Presentations will be invited in a parallel technical session at the conference. Presentation: Abstracts will be reviewed and, if accepted, submitters will be invited to present their work in a parallel session at the conference. Poster: Abstracts will be reviewed and, if accepted, posters will be displayed in the exhibition hall. RIN plans to encourage delegate interaction through poster presentations during the networking sessions. The best peer-reviewed papers will be invited to submit for consideration to be published in the Journal of Navigation, RIN added. Navigation 2021 will take place as a virtual conference. According to RIN, it will review the situation in 2021 and if possible run an in-person element to compliment the conference.
