This paper considers an #aerial #edge #computing (#AEC) paradigm, where #unmanned #aerial #vehicles (#UAVs) are deployed as edge servers to provide computing services to #mobile #devices (#MDs) in remote and hard-to-reach regions. Although offloading compute-intensive tasks to #edge #servers can improve the quality of experience and #reduce #energy #consumption of #MDs, it poses challenges in efficient system management due to the limitation in energy and bandwidth resources of the servers. To address this issue, they propose a green #AEC architecture where servers can harvest energy from renewable resources such as solar power. They formulate an optimization problem that aims to maximize the #MDs’ long-term satisfaction while guaranteeing sustainable operation for the UAVs by #controlling #computation #offloading and resource allocation decisions. They leverage the #Lyapunov #optimization #theory to handle #long-#term #energy #constraints in the formulated problem and then develop a #deep #deterministic #policy #gradient (#DDPG) algorithm to solve the problem considering a dynamic network environment. We also integrate prioritized experience replay and weighted importance sampling techniques into the DDPG algorithm to improve learning performance.@Quang-Vinh Do; Viet Quoc Pham @Zhaohui Yang; Won-Joo Hwang More details can be found at this link: https://lnkd.in/gmCFzTiG

Fun weekend project: NOAA APT (Automatic Picture Transmission) decoding with SDR (Software Defined Radio) involves receiving and processing weather images transmitted by NOAA satellites. These satellites continuously broadcast low-resolution weather images in the 137 MHz range using APT, an analog transmission format. To decode these signals, you'll need: SDR Receiver: Devices like RTL-SDR or SDRplay can tune into the NOAA satellite signals. Antenna: A VHF antenna (like a QFH or a turnstile antenna) optimized for 137 MHz helps to receive clear signals. Software: Programs like SatDump, WXtoImg, SDRSharp, or GQRX decode the raw signal into images. You'll need to set up the SDR software to tune to the correct frequency and record the APT transmissions. Pass Prediction Tools: Use tools like Heavens Above or GPredict to know when NOAA satellites will pass over your location. Once set up, the SDR captures the radio signal, which is then processed to generate weather images showing cloud cover, landmasses, and more.

A few tips on choosing the best satellite payload for your mission. The primary payload on a satellite is (usually) where the core value is generated. The bus and other subsystems support and facilitate the payload's operation, ensuring it has power, stability, computing resources, and communication bandwidth to perform well. But the payload is crucial to creating a successful (and profitable) mission. So how can you choose the best one for your needs? Here are a few tips: 1. Understand your SWAP-c budget ranges clearly before you start looking. But also remember that, in practice, these are likely to change as the mission develops, so ensure you'll get updated in real-time if they do. 2. Be clear on what accuracy or performance levels are both optimal and minimal for key criteria e.g. Ground Sampling Distance (GSD), bandwidth, or swath. 3. Look for systems used on missions with similar objectives to yours. If possible, try and speak to the mission team and end-users, as well as the payload supplier, to gauge the performance. 4. Understand how you intend to evaluate the supplier themselves, as well as the technology. Space missions are partnerships, often lasting a long time, so it is important that you try to ascertain how well you will work together. 5. Risk, reliability, and availability can trump performance. The highest precision system on the market may not be the best option if there's a chance that it won't deliver, or won't be delivered, when you need it. These are just a few ideas based on helping dozens of mission teams find suitable payload options for their project.
