The technology is now being developed further so that it can be miniaturized and prepared for commercialization. Besides first responders, the need for this technology spans industrial, military and space applications.
Arumugam and his team put together a field transmitter that fits on a backpack, and they’ve shown it can be shrunk down to a device that weighs 0.4 ounces (11.7 grams). Over the next few years, JPL will be working to shrink POINTER even further, until a transmitter is small enough to fit into a pocket or on a belt buckle.
Arumugam said a device of this type could be a lifesaver for future search-and-rescue teams, but has wide potential application beyond that.
“POINTER could be used in space robotics,” he said. “It could be used for tracking robots in underground tunnels, caves or under ice. They need to be able to navigate themselves, and we don’t have sensors today that would be able to track them. For us, this is a great opportunity to develop a technology for NASA and non-NASA uses.”
Ed Chow, manager of JPL’s Civil Program Office and POINTER program manager, said a cellphone-sized tracker would integrate well with another first responder technology called AUDREY. This artificial intelligence system would distribute real-time data across a team of first responders, but distributing relevant information depends on knowing each member’s exact location in the field.
“AUDREY is trying to provide suggested directions for firefighters lost in smoke,” Chow said. “But without knowing each member’s exact position and orientation, you can’t make those kinds of suggestions.”
