Dr. Charles Volk, Director of Advanced Technologies & Products for the Navigation & Maritime Systems Division with Northrop Grumman Electronics Systems Sector, recently gave a presentation to the Washington DC and Northern Virginia Joint AESS Chapter on Gyroscopes and Accelerometers. The presentation traced the development of inertial sensing from the nineteenth century beginnings of the gyroscope to the ubiquitous use of inertial sensors in systems in everyday products. He reviewed the major technologies that have been explored for use in inertial sensing and presented the development of inertial systems for north-finding, navigation and stabilization. While the advent of the Global Positioning System (GPS) threatened to relegate inertial sensing to a cheap component, he argued that the threats to GPS has reinvigorated the need to high performance inertial sensors and systems.
