Peer-to-Peer Cooperative Positioning

Magazine article, 2012

In this second part of a discussion of peer-to-peer cooperative positioning, we revisit the topic of sharing critical information across clusters of GNSS users. This article focuses on users within GNSS-challenged environments equipped with both a GNSS receiver and a terrestrial ranging system. Multiple methods for sharing position information across users are examined. The authors show that strategically sharing information can greatly enhance the availability of the position solutions to the network as a whole.
