About

Teodoro Aguilera is a leading researcher in acoustic local positioning systems (ALPS), a field critical for high-precision indoor navigation where GPS fails. His work focuses on overcoming fundamental challenges in ultrasonic positioning, particularly for moving targets in weak signal environments. Aguilera’s most cited paper (75 citations) introduces encoded emission beacons for centimeter-level accuracy, establishing ALPS as a low-cost, robust alternative for applications from robotics to augmented reality. He further advanced the field by systematically evaluating Zadoff–Chu, Kasami, and chirp encoding schemes (29 citations), identifying optimal signal designs for noise resilience. His research on robust airborne ultrasonic positioning (19 citations) and high-availability systems for poor coverage areas (5 citations) directly addresses the critical problem of signal attenuation and multipath interference, enabling reliable tracking even in challenging indoor spaces. Aguilera’s contributions have been instrumental in moving acoustic positioning from laboratory concepts to practical, deployable systems, making him a key figure in the development of next-generation indoor localization technologies.
