The Swarm Satellite Constellation Application and Research Facility (SCARF) and Swarm data products [PDF]

Earth, Planets and Space, 2013
Swarm, a three-satellite constellation to study the dynamics of the Earth’s magnetic field and its interactions with the Earth system, is expected to be launched in late 2013. The objective of the Swarm mission is to provide the best ever survey of the geomagnetic field and its temporal evolution, in order to gain new insights into the Earth system by ...

Intelligent Covert Satellite Communication for Military Robot Swarm [PDF]

IEEE Access, 2020
Military robot swarm becomes more and more important for contemporary military application. In order to satisfy sophisticated application scenarios, novel communication architecture for military robot swarm has to be conceived. In this paper, we propose a multi-carrier intelligent covert satellite communication (MCICSC) architecture based on ...

Estimation of Ion Temperature in the Upper Ionosphere Along the Swarm Satellite Orbits

Earth and Space Science, 2021
Ion temperature is one of the key parameters that provides insight into the thermal balance of the coupled ionosphere‐thermosphere system. Together with the temperatures of neutral and electron gases, it affects physical and chemical processes and ...

A Community-Based Construct Method for an Inter-Satellite Communication Network of Satellite Swarm

Entropy, 2023
An inter-satellite communication network of satellite swarm (ICNS) is created if the members of a satellite swarm communicate with each other via inter-satellite links (ISLs). ICNS can be constructed using the theory of complex networks. A link community is defined as two satellites between which the ISL has been established. The satellite swarm, whose
