NON LINEAR OPTIMIZATION APPLIED TO ANGLE-OF-ARRIVAL SATELLITE BASED GEO-LOCALIZATION FOR BIASED AND TIME-DRIFTING SENSORS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Multiple sensors are used in a variety of geolocation systems. Many use Time Difference of Arrival (TDOA) or Received Signal Strength (RSS) measurements to estimate the most likely location of a signal.

Inferring Helmet Compliance on E-Scooters Using Bluetooth and Angle-of-Arrival (AoA) Technology
IEEE Transactions on Instrumentation and MeasurementThe use of e-scooters and the associated head injuries have increased significantly in recent years. To protect the head and face of the riders, helmets are essential equipment, sometimes mandatory according to the regulations, which makes them an important research target. In this article, we propose a practical helmet monitoring system for e-scooters
