In the last decade, the Global Positioning Satellite (GPS) based navigation system has become a ubiquitous technology for both military and commercial users, so much so that many critical applications have become highly dependant on it. However, GPS capabilities are not continuously available — they are highly susceptible to interference, jamming and line-of-sight constraints especially in subterranean and urban environments. Sarnoff focuses its extensive experience in communications and networking to solve the challenges related to GPS-denied navigation.

Sarnoff offers capabilities that can provide absolute and relative location, positioning, navigation and mapping capabilities, even when operating in GPS-denied urban and subterranean environments. Enabled by mobile ad-hoc network communication, we link the outputs of multiple systems to detect and minimize the impact of measurement errors. Through this use of dynamic and continuous cross-modal feedback, Sarnoff technology is able to provide more robust and enhanced performance in situations when normal communication is typically unfeasible.

Initially designed to meet the needs of dismounted warfighters, this technology also has extensive applications in the commercial sector — particularly for first responders, utility workers and public safety inspectors. GPS-denied navigation capabilities enable communication and network operations in any environment. For utility workers operating in subterranean areas or warfighters stationed in environments where satellite signals are unavailable, this capability is critical.
