“…These results show that GammaNet achieves the desired background rejections of AdEPT, making it a serious consideration for use on-board the satellite for event classification. These performance estimates include no image compression, and downlink bandwidth afforded by current and near future satellite communication [11,[18][19][20]. No image compression was used as a conservative assumption due to the data handling system for the AdEPT satellite not yet being decided.…”

The Advanced Energetic Pair Telescope gamma-ray polarimeter uses a time projection chamber for measuring pair production events and is expected to generate a raw instrument data rate four orders of magnitude greater than is transmittable with typical satellite data communications. GammaNet, a convolutional neural network, proposes to solve this problem by performing event classification on-board for pair production and background events, reducing the data rate to a level that can be accommodated by typical satellite communication systems. In order to train GammaNet, a set of 1.1x10 6 pair production events and 10 6 background events were simulated for the Advanced Energetic Pair Telescope using the Geant4 Monte Carlo code. An additional set of 10 3 pair production and 10 5 background events were simulated to test GammaNet's capability for background discrimination. With optimization, GammaNet has achieved the proposed background rejection requirements for Galactic Cosmic Ray proton events. Given the best case assumption for downlink speeds, signal sensitivity for pair production ranged between 1.1±0.5% to 69±2% for 5 and 250 MeV incident gamma rays. This range became 0.1±0.1% to 17±2% for the worst case scenario of downlink speeds. The application of a feature visualization algorithm to GammaNet demonstrated decreased response to electronic noise and events exiting or entering the frame and increased response to parallel tracks that are close in proximity. GammaNet has been successfully implemented and shows promising results.

“…In 2016, the SOTA (Small Optical TrAnsponder) system, developed by NICT, was used to establish an optical communication link between a LEO satellite (SOCRATES) to ground connection with a ground station affiliated to the German aerospace center [148]. NASA, in collaboration with MIT Lincoln Laboratory, is currently developing a 200 Gbps optical communication system to be installed on an LEO Cubesat (small satellite) to deliver more than 50 Terabytes of information per day to a ground station, as apart of the TeraByte InfraRed Delivery (TBIRD) program [149]. Beyond the vast offered bandwidth, optical satellite links require small footprints devices that consume less energy compared to those operating in the microwave bands typically used for Earthsatellite communications.…”

With the ever-increasing demand for data and radio frequency spectrum becoming congested, Free Space Optics (FSO) may find a niche for situations where fiber is too expensive or too difficult to install. FSO is a cross-disciplinary field that draws from radio and fiber communication, astronomy, and even quantum optics, and it has seen major advances over the last three decades. In this tutorial-style review, we provide a broad overview of many of the important topics required to design, develop, and research the next generation of FSO technology.

“…A number of further demonstration missions are currently planned, such as NASA's Terabyte Infrared Delivery (TBIRD) mission, aiming at demonstrating a 100 Gbps link from a CubeSat to ground [34], or within the Optical Space Infrared Downlink (OSIRIS) programme of the German Aerospace Center (DLR), which aims at demonstrating optical downlinks from small satellites and CubeSats to Earth [35].…”

Recently, the availability of innovative and affordable COTS (Commercial Off-The-Shelf) technological solutions and the ever-improving results of microelectronics and microsystems technologies have enabled the design of ever smaller yet ever more powerful satellites. The emergence of very capable small satellites heralds an era of new opportunities in the commercial space market. Initially applied only to scientific missions, Earth observation and remote sensing, small satellites are now being deployed to support telecommunications services. This review paper examines the operational features of small satellites that contribute to their success. An overview of recent advances and development trends in the field of small satellites is provided, with a special focus on telecommunication aspects such as the use of higher frequency bands, optical communications, new protocols, and advanced architectures.
