Radio-Based Navigation for Environments Without GPS
With the goal of enabling navigation in environments where GPS is unavailable or unreliable, researchers are developing algorithms to fuse information across a network of small, low-power radio-frequency devices.
Low-Cost Localization Using Distributed Adaptable-Response Transponders
A deployable navigation network of small, low-cost radio transponders can help track the locations of first responders during rescue operations.
Airborne Radar Testbed
An aircraft outfitted with an advanced open-architecture radar system provides a platform for testing new radar technology.
Motion Under Rubble Measured Using Radar
Our see-through-wall sensor is a lightweight, portable technology that peers through rubble and debris of a disaster site to detect survivors.
Balloon-Based Resilient Communications
High-altitude balloons used as beyond-line-of-sight relays would provide communications nodes if satellite communications could not offer coverage in contested environments.
Applied Space Weather
New algorithms improve the resilience of satellite and RF systems to impacts from space weather.
