On April 19, Professor Gonzalo Seco Granados, member of the SPCOMNAV group (Signal Processing for Communications & Navigation) at the Autonomous University of Barcelona visited Gradiant’s facilities, using his stay in Vigo to teach the subject Positioning and Navigation Systems belonging to Sigma master’s degree from the University of Vigo.
During his visit, the researchers were able to enjoy the talk titled Evaluation of LTE positioning capabilities, during which the professor Seco discussed the possibilities derived from a system that combines in the same waveform, navigation and communications services (NAV-COM systems), and has not rejected future satellite systems evolve towards this type of approach, as for example the Galileo system. During the exposition, he analyzed the new elements in the LTE frame structure to support location-based services, presented some of the algorithms used for the delay calculation in multicarrier systems, and outlined some of the most recent results his research group has obtained in connection with the precision that these systems might offer under different environments and situations, thus allowing insight into the true potential of LTE. In this sense, it is noted that some of the problems illustrated during the presentation, have been addressed in his recent article Challenges in Indoor Global Navigation Satellite Systems: Unveiling its core features in signal processing, published in the Signal Processing Magazine.
Currently, Gradiant has considerable experience in LTE, as well as positioning systems, as the result of several years working in several related research lines and projects. In this sense, Gradiant, aware of the enormous potential of both technologies, pays great attention to the evolution of such systems, and participates in various projects related to these issues.
