Scientists from the Skoltech Space Center (SSC) have developed nanosatellite interplay algorithms for scientific measurements utilizing a tetrahedral orbital formation of CubeSats that change information and apply interpolation algorithms to create native maps of bodily measurements in actual time. The research presents an instance of geomagnetic discipline measurement, which exhibits that these information can be utilized by different satellites for perspective management and, due to this fact, offered on a data-as-a-service foundation. The analysis was printed within the journal Advances in Space Research.
SSC is the analysis lead throughout the Nanosatellites Swarm venture (“Roy MKA”) carried out by a consortium of a number of Russian universities and included within the ISS experimental program led by RSC Energia. “Roy MKA” goals to deploy autonomous teams of CubeSats and confirm their swarm behavior.
For one of the “Roy MKA” experiments, SSC researchers steered a tetrahedral formation, which offers a capability to measure the geomagnetic discipline at any level on orbit. The system is absolutely autonomous, which implies that satellites can course of and replace measurement information on board and predict magnetic discipline values by interpolation.
“We use the Kriging interpolation which helps to select the magnetic field values in accordance with its characteristics (autocorrelation). Since the magnetic field is three-dimensional, we have to use a tetrahedron, the simplest three-dimensional simplex with three points on a plane. Thus, we have chosen a 4-satellite formation as the smallest possible configuration for the task. Our project may be the first to create such a configuration of nanosatellites,” lead writer and Skoltech PhD scholar Anton Afanasev explains.
The research demonstrated that the Kriging interpolator is a common software in the case of processing information from small satellites. Satellites change information about their positions and measurements to create a self-organizing system succesful of demonstrating collective behavior and performing duties widespread for the constellation, which constitutes the important thing aim of the “Roy MKA” venture.
“An important practical outcome of this study is that it can improve the performance of the attitude control and station-keeping systems that use magnetometers (magnetic field sensors). Notably, improved attitude control can also be used by other spacecraft that happen to be in close proximity to the constellation of the satellites that exchange magnetic field data and make them more accurate using the Kriging algorithms. Processing swarm measurements can evolve into a GPS-type service, which will enable distributing magnetic field values rather than object velocities and coordinates,” Anton provides.
The new technique can be utilized to construct giant constellations at a decrease complete price by utilizing inexpensive sensors.
