Artificial intelligence (AI) is paving the way for a new era of algorithms focusing directly on information contained in data, autonomously extracting relevant features given application. While initial paradigm was to have these applications run by server hosted processor, recent advances microelectronics provide hardware accelerators with an efficient ratio between computation and energy consumption, enabling implementation AI “at edge.” In this only meaningful useful data are...
The increasing demand for high-resolution hyperspectral images from nano and microsatellites conflicts with the strict bandwidth constraints downlink transmission. A possible approach to mitigate this problem consists in reducing amount of data transmit ground through on-board processing images. In paper, we propose a custom Convolutional Neural Network (CNN) deployed nanosatellite payload select eligible transmission ground, called CloudScout. latter is installed on Hyperscout-2, frame...
In recent years, research in the space community has shown a growing interest Artificial Intelligence (AI), mostly driven by systems miniaturization and commercial competition. particular, application of Deep Learning (DL) techniques on board Earth Observation (EO) satellites might lead to numerous advantages terms mitigation downlink bandwidth constraints, costs, increment satellite autonomy. this framework, CloudScout project, funded European Space Agency (ESA), represents first time...
The third gaia data release (DR3) provides a wealth of new products. early part the release, Gaia EDR3, already provided astrometric and photometric for nearly two billion sources. full now adds improved parameters compared to DR2 radial velocities, astrophysical parameters, variability information, light curves, orbits Solar System objects. improvements are in terms number sources, variety parameter precision, accuracy. For first time, DR3 also sample spectrophotometry spectra obtained with...
Advancements in technology have driven the miniaturization of embedded systems, making them more cost-effective and energy-efficient for wireless applications. As a result, number connectable devices Internet Things (IoT) networks has increased significantly, creating challenge linking effectively economically. The space industry long recognized this invested satellite infrastructure IoT networks, exploiting potential edge computing technologies. In context, it is critical importance to...
As the number of earth observation missions in-creases, together with images acquired by satel-lites, need for optimizing onboard memory allocation and bandwidth to ground is becoming more critical. Currently, large players in space industry face this developing custom Instrument Control Units (ICUs), which can only be employed single mission they have been designed for. The unavailability flexible, programmable, space-grade solutions ready integrated as building blocks keeps costs such...
The current Covid-19 pandemic has limited direct contacts among people, since the virus is usually widespread by drops of saliva. Then, this world outbreak brought need to track patients' positions, especially verify respect quarantine regulations for infected people and their strict contacts. Moreover, conditions elderly high risk patients should be continuously monitored, minimising, at same time, exposure general practitioners. Among several solutions available on market, telemedicine...
In recent years, the number of Earth Observation missions has been exponentially increasing. Satellites dedicated to these usually embark with payloads that produce large amount data and need be transmitted towards ground stations, in time-limited windows. Moreover, noisy nature link between satellites stations makes it hard achieve reliable communication. To address problems, a standard for flexible advanced coding modulation scheme high-rate telemetry applications defined by Consultative...
During the last years, mobility of people with upper limb disabilities and constrained on power wheelchairs is empowered by robotic arms. Nowadays, even though modern manipulators offer a high number functionalities, some users cannot exploit all those potentialities due to their reduced manual skills, if capable driving wheelchair means proper Human–Machine Interface (HMI). Owing that, this work proposes low-cost manipulator realizing only simple tasks controllable three different graphical...
Today's space missions perform increasingly complicated tasks on-board satellites, ranging from processing data to running artificial intelligence algorithms enable new applications.
