The main focus of the LOPSI group is the design and development of Local Positioning Systems (LPS) capable of locating, tracking, and guiding people in indoor and outdoor environments, where GPS receivers are not operative or reliable.

Also, you can collaborate and improve the app (and other related Matlab tools) in our GitLab repository that you can find in https://lopsi.car.upm-csic.es/GetSensorDataSuite. Please collaborators are welcome.

Jan 19, 2015 · The LOPSI group is involved in projects ranging from fundamental research, to more applied activity, aimed to the development of technology for interested partners. Here is a list of recent projects which we have led or in which we have participated:

Jan 20, 2015 · The LOPSI group performs research and technological development in localization systems operative in indoor / GPS-denied environments, and able to offer a typical precision of 1 meter. The main operative platform for indoor positioning is a smartphone.

The LOPSI group is currently composed of two senior PhD members: Dr. Antonio Ramón Jiménez Ruiz (antonio.jimenez) ( google scholar profile ) Dr. Fernando Seco Granja (fernando.seco) ( personal page )( google scholar profile )

The LOPSI group uses ultrasonic technology for high accuracy positioning in small indoor areas. By measuring the time-of-flight (TOF) of ultrasonic signals propagating from several static beacons to a mobile node, its position can be computed by multilateration techniques, usually with an accuracy around 1 cm.
