Researchers study collective behavior of nanosatellites
Write a comment
Scientists from the Skoltech Space Center (SSC) have developed nanosatellite interaction algorithms for scientific measurements using a tetrahedral orbital formation of CubeSats that exchange data and apply interpolation algorithms to create local maps of physical measurements in real time. The study presents an example of geomagnetic field measurement, which shows that these data can be used by other satellites for attitude control and, therefore, provided on a data-as-a-service basis. The research was published in the journal Advances in Space Research.
SSC is the research lead within the Nanosatellites Swarm project ("Roy MKA") performed by a consortium of several Russian universities and included in the ISS experimental program led by RSC Energia. "Roy MKA" aims to deploy autonomous groups of CubeSats and verify their swarm behavior.
For one of the "Roy MKA" experiments, SSC researchers suggested a tetrahedral formation, which provides an ability to measure the geomagnetic field at any point on orbit. The system is fully autonomous, which means that satellites can process and update measurement data on board and predict magnetic field values by interpolation.
"We use the Kriging interpolation which helps to select the magnetic field values in accordance with its characteristics (autocorrelation).
Roscosmos has lost several contracts for satellite launches due to 'mean' US sanctions

The Russian State Space Corporation Roscosmos has lost several potential contracts for launching foreign satellites due to Washington's sanctions, Roscosmos Director General Dmitry Rogozin told Sputnik on Monday.
"I am aware of several similar situations when the customers would like to use our rockets but were forced to refuse because of the mean US sanctions. This happens if the spacecra First results from Fermilab's Muon g-2 experiment strengthen evidence of new physics

The long-awaited first results from the Muon g-2 experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way that is not predicted by scientists' best theory, the Standard Model of particle physics. This landmark result, made with unprecedented precision, confirms a discrepancy that has been gnawing at researchers Space Debris

On 20 April 2021, ESA will host the 8th European Conference on Space Debris from Darmstadt, in Germany. Scientists, engineers, industry experts and policy makers will spend the virtual four day conference discussing the latest issues surrounding space debris. They will exchange the latest research, try to come up with solutions for potential problems and define the future direction of any necessary action.
There are currently over 129 million objects larger than a millimetre in orbits around Earth. These range from inactive satellites to flakes of paint. But no matter how small the item of debris, anything travelling up

China's Long March-7 Y3 rocket, which will launch the cargo craft of China's space station, has arrived at its launch site in southern China's Hainan Province.
The rocket, alongside the Tianzhou-2 cargo craft that has already been transported to the Wenchang Spacecraft Launch Site, will be assembled and tested at the launch site, the China Manned Space Engineering Office (CMSEO) said on Mo Four satellites planned to start space-based network

The southernmost province of Hainan plans to launch four satellites around the end of this year, thus beginning construction of the island's first space-based network, according to a project official.
Yang Tianliang, chief designer of the Hainan Earth-Observation Satellite Constellation System, said recently that four Hainan 1-series optical Earth-observation satellites have been assembled Russia to Launch New Meteor-M Weather Satellite in Late November

The next Meteor-M model Russian meteorological satellite will be launched from the Vostochny spaceport on 30 November, Sputnik learned on Monday from the printed materials of an international space forum taking place at the Lomonosov Moscow State University (MSU).
The chief of Russia's state space corporation Roscosmos, Dmitry Rogozin, said last November that the Meteor-M satellite, number Differences of cloud top height between satellites and ground-based radar revealed

Clouds play a key role in balancing incoming and outgoing solar and thermal radiation. This is a critical process in the earth-atmosphere system. Monitoring cloud height, particle size, particle concentration, etc. are integral to understanding climate dynamics and global climate change.
These physical attributes determine the radiative forcing effect of a cloud, or how much incoming radia UK space firm In-Space Missions Limited Announces Major Expansion And Job Creation Plans
