Recent advancements in free-space optical (FSO) communications are enabling a breakthrough satellite miniaturization and data transfer rates. The CubeISL laser communication terminal (LCT), development of the German Aerospace Center (DLR), is set to showcase inter-satellite links at 100 Mbps downlinks 1 Gbps once it launches 2025. This technology aims establish itself as cutting-edge solution for efficient CubeSat communications, delivering high To validate its capabilities, underwent...
ABSTRACT Satellite‐based laser communication is an emerging technology that finding its way from research to industry. Compared radio frequency (RF) systems, it has a more efficient size, weight, and power budget and, furthermore, license free. The required space terminals can be designed in different sizes, depending on the mission needs. Data rate requirements range CubeSats with Mb/s large satellites Gb/s data rates sometimes even Tb/s. This enables, for example, use of high‐resolution...
The increasing request for higher data rates and the technical limitations of traditional radio-frequency channels in intersatellite communication requires solutions to overcome these obstacles. German Aerospace Center (DLR) has a long heritage optical air-to-ground space-to-ground transmission. Due its high rates, resistance against interferences being free from regulations like International Telecommunication Union (ITU), Free Space Optical (FSO) provides challenges satellite...
Satellite miniaturization and sinking costs of manu-facturing launches are bringing Moon missions in the focus many space companies agencies. However, achieving desired data rates on CubeSats over long ranges is proving increasingly challenging with traditional radio-frequency communication systems. Free-space optical (FSO) communications offer a compact, light, low-power alternative higher throughput fewer limitations (e.g., governmental regulations, channel interference, eavesdropping...)....
Free-Space Optical (FSO) communication is a technology that enables ultra-high-rate data exchange and will be crucial in enabling secure Quantum Key Distribution (QKD) over long distances. However, FSO systems are comparatively complex technologies, comprising variety of subsystems all have to work together coordinated way. Hence, assessing the feasibility establishing (classical or quantum) link given scenario difficult task itself. Here we introduce QCalc, software tool aims at easing...
The EAGLE-1 mission aims to develop Europe's first sovereign, end-to-end space-based quantum key distribution (QKD) system. is led by the European Space Agency (ESA) and SES in collaboration with several National Agencies private partners. state-of-the-art QKD system will consist of a payload on board low Earth orbit (LEO) satellite, optical ground stations, operational networks, management represents major step for next-generation communication infrastructures, delivering valuable technical...
