A new way of improving global ionospheric maps by ionospheric tomography: consistent combination of multi-GNSS and multi-space geodetic dual-frequency measurements gathered from vessel-, LEO- and ground-based receivers
(2020-08)
Article
Restricted access - publisher's policyIn this work, we introduce a new way of improving the sligthly best performing global ionospheric model (GIM) within the International GNSS Service, the UQRG produced by UPC-IonSAT with the TOMION dual-layer voxel model ... -
Assessment of noise of MEMS IMU sensors of different grades for GNSS/IMU navigation
(Multidisciplinary Digital Publishing Institute (MDPI), 2024-03-19)
Article
Open AccessInertial measurement units (IMUs) are key components of various applications including navigation, robotics, aerospace, and automotive systems. IMU sensor characteristics have a significant impact on the accuracy and ... -
Contributions to the 3D ionospheric sounding with GPS data
(Universitat Politècnica de Catalunya, 2004-03-15)
Doctoral thesis
Open AccessLa tesi proposa una sèrie d'algoritmes destinats a obtenir informació del contingut d'electrons lliures presents a la ionosfera. El tipus de dades que s'utilitzaran seran bàsicament les corresponents a receptors de dades ... -
Electron density extrapolation above F2 peak by the linear Vary-Chap model supporting new Global Navigation Satellite Systems-LEO occultation missions
(2017-08)
Article
Open AccessThe new radio-occultation (RO) instrument on board the future EUMETSAT Polar System-Second Generation (EPS-SG) satellites, flying at a height of 820 km, is primarily focusing on neutral atmospheric profiling. It will also ... -
Precise ionospheric electron content monitoring from single- frequency GPS receivers
(2018-10-01)
Article
Open AccessThe number of existing global positioning system (GPS) single-frequency receivers continues growing. More than 90% of GPS receivers are implemented as low-cost single-frequency chipsets embedded in smartphones. This provides ... -
Real-time tomographic inversion of truncated ionospheric GNSS radio occultations
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-06-19)
Article
Open AccessThis paper presents a new way of combining Abel inversion and the Chapman model with a linearly increasing scale height to retrieve ionospheric electron density vertical profiles from truncated-sounding radio-occultation ... -
Study of several interpolation schemes to provide ionospheric corrections for navigation
(2003-02)
Conference report
Open AccessSince the development of space based geodesic techniques, the increasing of the positioning accuracy has been a major goal. In this context, the effect of the ionosphere has been a key issue to be taken into account to ...
