Integrated processing of ground- and space-based GPS observations: improving GPS satellite orbits observed with sparse ground networks
; ; ; ; (Journal of Geodesy, 2020-10-10)
The precise orbit determination (POD) of Global Navigation Satellite System (GNSS) satellites and low Earth orbiters (LEOs) are usually performed independently. It is a potential way to improve the GNSS orbits by integrating ... -
September 2019 Antarctic Sudden Stratospheric Warming: Quasi-6-Day Wave Burst and Ionospheric Effects
; ; ; ; Siddiqui, T.; Kervalishvili, G.; Laštovi?ka, J.; Kozubek, M.; Ward, W.; Themens, D. R.; Kristoffersen, S.; (Geophysical Research Letters, 2020)
An exceptionally strong stationary planetary wave with Zonal Wavenumber 1 led to a sudden stratospheric warming (SSW) in the Southern Hemisphere in September 2019. Ionospheric data from European Space Agency's Swarm satellite ... -
The Mag.num core field model as a parent for IGRF-13, and the recent evolution of the South Atlantic Anomaly
;; ; ; ; (Earth, Planets and Space, 2021-02-11)
We present the GFZ candidate field models for the 13th Generation International Geomagnetic Reference Field (IGRF-13). These candidates were derived from the Mag.num.IGRF13 geomagnetic core field model, which is constrained ...
