RaVÆn: unsupervised change detection of extreme events using ML on-board satellites
Scientific Reports, 2022 Applications such as disaster management enormously benefit from rapid availability of satellite observations. Traditionally, data analysis is performed on the ground after being transferred—downlinked—to a ground station.

On Orbit Demonstration of Pointing Accuracy of Ground Antennas by a Flying GEO Satellite
Sakarya University Journal of Computer and Information Sciences, 2023 Geostationary Satellites (GEO) are being used commonly in communication market. The service providers uplink or downlink the signal by using their dedicated antennas (whether with or without tracking capability) to the GEO satellite.

Optics Express, 2012 Optical communication is a high-capacity method that can handle considerable satellite data. When common-fiber optical devices such as optical fiber amplifiers based on single mode fibers are used in free-space laser communication systems, the laser beam has to be coupled to a single-mode fiber.

Analysis of X-Band Link Performance Degradation Caused by Adjacent Satellite [PDF]
Journal of Astronomy and Space Sciences, 2011 As more satellites are designed to downlink their observed image data through the X-band frequency band, it is inevitable that the occupied bandwidth of a target satellite will overlap with that of other X-band downlink satellites. For sun-synchronized
