Position and timing signals from global navigation satellite systems (GNSS) have become the primary source of navigation for vehicles across air, land and sea. But how do pilots or unmanned systems navigate when GNSS signals aren’t available? GNSS has seen a significant increase in intentional and unintentional disruptions including jamming and spoofing. In this podcast navigation experts Ben Mohr and Mohan Jacob discussing two suites of Honeywell offerings Alternative Navigation and Resilient Navigation aimed to help manned and unmanned aircraft operate when navigation is denied or unavailable.  They answer questions like “what are the most common types of denied environments” and “Why, how we stay ahead of this.” Building on decades of leadership in inertial navigation systems for all kinds of aircraft and spacecraft, Honeywell engineers have made enormous progress in alternative navigation, aided by evolutionary advancements in sensors and other enabling technologies. Honeywell was one of the first companies to successfully demonstrate alternative navigation technologies in a GPS-denied environments. In this podcast we touch on the issue and how best to tackle it.
