A new method to determine the optimal thin layer ionospheric height and its application in the polar regions
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-06-23)
Article
Accés obertIn this paper, a feasibility study of a microwave antenna-based sensor is proposed for in vitro experiments for monitoring blood glucose levels. The proposed device consists of a square-ring incorporated within a fully ... -
A Worldwide ionospheric model for fast precise point positioning
(Institute of Electrical and Electronics Engineers (IEEE), 2015-03-03)
Article
Accés obertFast precise point positioning (Fast-PPP) is a satellite-based navigation technique using an accurate real-time ionospheric modeling to achieve high accuracy quickly. In this paper, an end-to-end performance assessment of ... -

gLAB hands-on education on satellite navigation
(Universitat Politècnica de Catalunya, 2022-04-29)
Comunicació de congrés
Accés obertThe Global Navigation Satellite System (GNSS) allows computing the Position, Velocity and Time (PVT) of users equipped with appropriate hardware (i.e. an antenna and a receiver) and software. The latter estimates the PVT ... -
Implementation of a testbed for GNSS-R payload performance evaluation
(Institute of Electrical and Electronics Engineers (IEEE), 2020-05-28)
Article
Accés obertThe functional performance of space-borne instruments must be validated on ground before and after satellite integration. The effects of radio-frequency interference are also becoming more important, even in protected bands ... -
Measuring phase scintillation at different frequencies with conventional GNSS receivers operating at 1 Hz
(2019-10-01)
Article
Accés obertIonospheric scintillation causes rapid fluctuations of measurements from Global Navigation Satellite Systems (GNSSs), thus threatening space-based communication and geolocation services. The phenomenon is most intense in ...
