Spacecraft computing cluster based on cots components for solving earth remote sensing problems
Every year requirements for satellites become more sophisticated and tight that force processing units to have necessary performance and on-board information volume, primarily related to the complexity of real-time control algorithms and the handling of large amounts of data generated by the payload (optical, radar and communication systems) and sensors. The article considers the task of creating a computing cluster structure with high performance and relatively low cost based on widely available single-board minicomputers. An on-board computer (OBC) cluster system based on single-board computers is proposed, which allows us to distribute the computing load between several nodes and triple redundancy. COTS-based cluster system (Commercial off-the-shelf) is proposed to be used as the OBC of the Earth Remote Sensing University Nano-satellite (ERSUN) to improve the performance of computation and to reduce the cost of components.
