GNSS Radio Occultation Inversion Methods and Reflection Observations in the Lower Troposphere

Autor: Sievert, Thomas

GNSS Radio Occultation (GNSS-RO) is an opportunistic Earth sensing technique where GNSS signals passing through the atmosphere are received in low Earth orbit and processed to extract meteorological parameters. As signals are received along an orbit,

Comparing Two Generations of Embedded GPUs Running a Feature Detection Algorithm

Autor: Danielsson, Max, Grahn, Håkan, Sievert, Thomas, Rasmusson, Jim

Graphics processing units (GPUs) in embedded mobile platforms are reaching performance levels where they may be useful for computer vision applications. We compare two generations of embedded GPUs for mobile devices when running a state-of-the-art fe

Supervised Detection of Ionospheric Scintillation in Low-Latitude Radio Occultation Measurements

Autor: Ludwig Barbosa, Vinícius, Sievert, Thomas, Carlström, Anders, Pettersson, Mats, Vu, Viet Thuy, Rasch, Joel

Publikováno v: Remote Sensing, Vol 13, Iss 1690, p 1690 (2021)

Global Navigation Satellite System (GNSS) Radio Occultation (RO) has provided high- quality atmospheric data assimilated in Numerical Weather Prediction (NWP) models and climatol- ogy studies for more than 20 years. In the satellite–satellite GNSS-

Using A Sliding Window Phase Matching Method for Imaging of GNSS Radio Occultation Signals

Autor: Sievert, Thomas, Rasch, Joel, Carlström, Anders, Ludwig Barbosa, Vinícius, Pettersson, Mats, Vu, Viet Thuy

Publikováno v: Remote Sensing, Vol 13, Iss 970, p 970 (2021)

Global Navigation Satellite System Radio Occultation (GNSS-RO) is a technique used to sound the atmosphere and derive vertical profiles of refractivity. Signals from GNSS satellites are received in a low-Earth orbit, and they are then processed to pr
