In this episode of the Voices from DARPA podcast, Dr. John Burke, a program manager since 2017 in the agency’s Microsystems Technology Office (MTO), goes deep, quantum-mechanics deep. The miniaturized, affordable, and ultrastable atomic clocks he hopes to make possible would kick in if the GPS system were to go down due to natural or adversarial actions. Such clocks could keep the military machine viable while also preserving or even enhancing the operation of civilian must-haves ranging from financial transactions to ridesharing (think Uber and Lyft). Burke has teams of researchers pursuing magnificently sensitive magnetometers for detecting objects, materials, and activities otherwise hidden underground, underwater, or behind bone.

The Tactical Technology Office is holding a Proposers Day to provide information on the structure and objectives of the Angler program. Angler seeks to migrate advancements from terrestrial and space-based robotics, terrestrial autonomous manipulation, and underwater sensing technologies into the realm of undersea manipulation, with specific focus on long-distance, seabed-based missions. Specifically, the program aims to discover innovative autonomous robotic solutions capable of navigating unstructured ocean depths, surveying expansive underwater regions, and physically manipulating manmade objects of interest.
The military relies heavily on the Global Positioning System (GPS) for positioning, navigation, and timing (PNT), but GPS access is easily blocked by methods such as jamming. In addition, many environments in which our military operates (inside buildings, in urban canyons, under dense foliage, underwater, and underground) have limited or no GPS access. To solve this challenge, Adaptable Navigation Systems (ANS) seeks to provide GPS-quality PNT to military users regardless of the operational environment.
DARPA's Angler program seeks to develop undersea autonomous robotic solutions capable of navigating ocean depths, surveying wide areas, and physically manipulating manmade objects of interest on the sea floor. The program builds on the agency's previous advances in autonomous robotic manipulation on Earth and in space, and aims to process mission commands, sensor inputs, and information about the deep ocean environment to complete tasks with no human intervention.
For decades, Global Positioning System (GPS) technology has been incorporated into vehicles and munitions to meet DoD requirements for precision guidance and navigation. GPS dependence creates a critical vulnerability for many DoD systems in situations where the GPS signal is degraded or unavailable.
