Study asks: Can cell phone signals help land a plane?
Researchers from Sandia National Laboratories and The Ohio State University are taking experimental navigation technology to the skies, pioneering a backup system to keep an airplane on course when it cannot rely on global positioning system satellites.
Summer Czarnowski, a geosciences intern at Sandia National Laboratories, holds a line tethered between a scientific payload and a weather balloon prior to launch at Moriarty Airport in New Mexico in July. The payloads, which consist of electronic packages attached to a pair of antennas and bundled into an insulated foam cooler, hold the key to understanding signals high above the clouds. Sandia Labs has major research and development responsibilities in nuclear deterrence, global security, defense, energy technologies and economic competitiveness, with main facilities in Albuquerque, New Mexico, and Livermore, California.
