Here’s an example of the progression of raw digital numbers to non-uniformity-corrected imagery and, finally, flicker-compensated imagery for a single dark scene. This represents an essential step for calibrating satellite imaging sensors. #remotesensing #earthobservation #spacetechnology #satellite #newspace #smallsat #satellitedata #spacetech #cubesat #satelliteimagery

Radio connections for uncrewed systems are going through significant changes. ➡️Cognitive radio is increasingly being adopted, using software-defined radio to analyse the local spectrum and find areas that are clear, reducing the power required and extending battery life. ➡️Mobile ad-hoc networks are being used with swarms of UAVs to enhance radio connectivity, sharing data about the spectrum across a wide area. ➡️New, lightweight antenna designs with multiple feeds and beamforming are also improving the performance of radio links in the air, allowing for longer range connections beyond the visual line-of-sight or reducing the power needed for close work. ➡️Meanwhile, machine learning and artificial intelligence are being adopted in radio systems to boost cognitive architectures and the efficiency of connections, especially for high-bandwidth video. ➡️At the same time, millimetre-wave radio technology (mmWave) is maturing to provide higher-bandwidth video links that are less susceptible to interference. The technology is maturing to be cost effective for vehicles on the ground and for high-altitude pseudo satellites, where power is a critical consideration.

Coherent Two-Photon Atmospheric Lidar Based on Up-Conversion Quantum Erasure The Hong-Ou-Mandel (HOM) effect, also called two-photon interference, which is pivotal in quantum information processing, serves as the foundation for our coherent two-photon wind detection method, achieving time-frequency discrimination. Our method capitalizes on the complete erasure of phase and color distinctions with up-conversion detectors, allowing for the observation of HOM interference among independently sourced photons without necessitating delay tuning or active synchronization. The integration of quantum erasure enhances the bandwidth in both space-time and frequency domains, paving the way for ultrafast, continuous velocity detection up to tens of km/s. The demonstration uses just 14% pulse energy of previous levels, enabling a wind detection range up to 16 km, marking a quantum leap in remote sensing capabilities. https://lnkd.in/dsyPixRT

The first commercial hyperspectral satellite for self-service tasking! The last week of April 2024 is special. Customers on the Eartheye Space's Sat-Tasking platform can ‘task’ the first commercial hyperspectral satellite. Having offered the first thermal infrared and greenhouse gas sensors for direct tasking, Eartheye Space is again at the forefront to bring yet another sensor as the first for direct tasking. This time, it is the tens of bands with ~5m resolution hyperspectral imaging.   Customers can combine hyperspectral imaging with other sensor modalities on the platform in the same tasking workflow–akin to Uber Eats for sensors/ satellites–to solve wicked problems (more in another post). We will soon deliver information feeds based on the hyperspectral data and fuse them with other sensor modalities to deliver use cases of interest to early customers. With access to over 300 satellites with multiple sensor modalities such as #multispectral, #radar, #thermalinfrared, #greenhousegas, #ais, #rfcomms, #fullmotionvideo for self-service tasking, Eartheye Space has brought the affordability of direct tasking to the new lows.     We offer Sat-Tasking at an affordable 𝐔$5000 𝐩𝐞𝐫 𝐲𝐞𝐚𝐫 subscription for any organization–big or small–as long as the registrant passes our stringent KYC (Know Your Customer) process. Do you have the chops to task satellites?

𝗥𝗮𝗶𝗻𝗯𝗼𝘄𝘀 𝗶𝗻 𝘁𝗵𝗲 𝘀𝗸𝘆… 𝗮𝗻𝗱 𝗼𝗻 𝘁𝗵𝗲 𝗴𝗿𝗼𝘂𝗻𝗱? While reviewing satellite imagery, we stumbled upon this stunning “rainbow airplane”! But don’t let your eyes deceive you - this isn’t a technicolor jetliner flying over farmland; it’s a fascinating artifact created by the TDI (Time-Delay Integration) nature of MSI sensors. Here’s what happened: ⏺  Multi-Spectral Imagery (MSI) sensors capture scenes in multiple spectral bands—each at a slightly different moment in time. ⏺  If a vehicle (like this airplane) is moving during image acquisition, the sensor records its position in each spectral band at different locations. ⏺  The result? A rainbow effect that looks like something straight out of a dream! This colorful glitch is a reminder of the incredible technology behind satellite imagery and how movement in dynamic scenes can create unexpected results. #RemoteSensing #SatelliteImagery #ScienceInAction #EarthObservation #RainbowAirplane #GeospatialTech #Geospatial #GIS

What a great example of how TDI works and how these types of sensor processes can create artifacts in the collected data.

Another key step in making satellites smart! As Space gets more and more crowded, it's critical that satellites can see and understand their environment and can take actions based on it.
