DARPA’s Adaptable Sensor System (ADAPT) program aims to transform how unattended sensors are developed for the military by using an original design manufacturer (ODM) process similar to that of the commercial smartphone industry. The goal is to develop low-cost, rapidly updatable intelligence, surveillance and reconnaissance (ISR) sensors in less than a year, a marked improvement to the current three-to-eight year development process.
Degraded visibility—which encompasses diverse environmental conditions including severe weather, dust kicked up during takeoff and landing and poor visual contrast among different parts of terrain—often puts both the safety and effectiveness of tactical helicopter operations at risk. Current sensor systems that can provide the necessary visualization through obscurants struggle with latency and are too large, heavy and power-intensive to comply with military rotary wing operations.

Many essential military capabilities—including autonomous navigation, chemical-biological sensing, precision targeting and communications—increasingly rely upon laser-scanning technologies such as LIDAR (think radar that uses light instead of radio waves). These technologies provide amazing high-resolution information at long ranges but have a common Achilles heel: They require mechanical assemblies to sweep the laser back and forth. These large, slow opto-mechanical systems are both temperature- and impact-sensitive and often cost tens of thousands of dollars each—all factors that limit widespread adoption of current technologies for military and commercial use.
Find a way to replace a large, heavy and expensive technology with an equivalent one that’s a lot smaller, lighter and cheaper and you have a shot at turning a boutique technology into a world changer. Think of the room-sized computers of the 1940s that now are outpowered by the run-of-the-mill central processing unit in laptop computers. Or the miniaturized GPS components that contribute geolocation smartness in cell phones. DARPA program manager Joshua Conway has another shrinking act in mind: packing the light-catching powers of bulky lens-filled telescopes onto flat, semiconductor wafers that are saucer-sized or smaller, featherweight and cheap to make.
Airspace for the flying public today is perpetually congested yet remarkably safe, thanks in no small part to a well-established air traffic control system that tracks, guides and continuously monitors thousands of flights a day. When it comes to small unmanned aerial systems (UAS) such as commercial quadcopters, however, no such comprehensive tracking system exists.
