Reconstructing GRACE-type time-variable gravity from the Swarm satellites [PDF]

open access: yesScientific Reports, 2021
The Gravity Recovery and Climate Experiment (GRACE) mission has enabled mass changes and transports in the hydrosphere, cryosphere and oceans to be quantified with unprecedented resolution. However, while this legacy is currently being continued with the

Ionospheric plasma irregularities studied with Swarm satellites [PDF]

open access: yesE3S Web of Conferences, 2018
To study and characterise the ionospheric plasma irregularities at all latitudes, one can employ in-situ measurements by satellites in polar orbits, such as the European Space Agency’s Swarm mission.

On the origin of satellite swarms [PDF]

open access: yes, 2009
For a species to develop in nature, two basically two things are needed: an enabling technology and a "niche". In spacecraft design the story is basically the same. Both a suitable technology and a niche application need to be there before a new generation of spacecraft can be developed.

Swarm-TEC Satellite Measurements as a Potential Earthquake Precursor Together With Other Swarm and CSES Data: The Case of Mw7.6 2019 Papua New Guinea Seismic Event

open access: yesFrontiers in Earth Science, 2022
On May 14, 2019, a strong Mw = 7.6 shallow earthquake occurred in Papua New Guinea. This paper explores for the first time the analysis of total electron content (TEC) products measured for 6 months by GPS antenna onboard Swarm satellites, to detect ...

A New Ionospheric Index to Investigate Electron Temperature Small-Scale Variations in the Topside Ionosphere

open access: yesUniverse, 2021
The electron temperature (Te) behavior at small scales (both spatial and temporal) in the topside ionosphere is investigated through in situ observations collected by Langmuir Probes on-board the European Space Agency Swarm satellites from the beginning ...

Satellite swarm survey and new conceptual design for Earth observation applications

open access: yesEgyptian Journal of Remote Sensing and Space Sciences, 2021
The new trend in Earth observation applications is to use a set of low-cost, simple and short development time satellites. A Swarm mission of twelve CubeSats as imaging nodes, besides, hub Microsatellite was already proposed to fulfill the earth ...

The Correlation between Ionospheric Electron Density Variations Derived from Swarm Satellite Observations and Seismic Activity at the Australian–Pacific Tectonic Plate Boundary

open access: yesRemote Sensing, 2023
Swarm electron density (Ne) observations from the Langmuir probe (LP) can detect ionospheric disturbances at the altitude of a satellite. Along-track satellite observations provide a large number of very short observations of different places in the ...
