PyrSat - Prevention and response to wild fires with an intelligent Earth observation CubeSat

Forest fires are a pervasive and serious problem. Besides loss of life and extensive environmental damage, fires also result in substantial economic losses, not to mention property damage, injuries, displacements and hardships experienced by the affected citizens. This project proposes a low-cost intelligent hyperspectral 3U CubeSat for the production of fire risk and burnt area maps. It applies Machine Learning algorithms to autonomously process images and obtain final data products on-board the satellite for direct transmission to users on the ground. Used in combination with other services such as EFFIS or AFIS, the system could considerably reduce the extent and consequences of forest fires

Modeling and Analysis of Power Processing Systems

The feasibility of formulating a methodology for the modeling and analysis of aerospace electrical power processing systems is investigated. It is shown that a digital computer may be used in an interactive mode for the design, modeling, analysis, and comparison of power processing systems

Handbook for New Actors in Space

Driven by Cold War tensions between the US and the Soviet Union, the space race began almost 60 years ago. Each power was racing to accomplish new feats in space and demonstrate its superiority. In 2017, while much remains the same, much has changed. Space actors comprise a wide variety of national and non-governmental entities comprising diverse rationales, goals, and activities. More than 70 states, commercial companies, and international organizations currently operate more than 1,500 satellites in Earth orbit. Driven largely by the commoditization of space technology and the lowering of barriers to participation, the number of space actors is growing. This broadening of space has both advantages and disadvantages. On the positive side, it is leading to greatly increased technological innovations, lower costs, and greater access to the beneficial capabilities and services offered by satellites. However, the accelerated growth in space activities and the influx of new actors has the potential to exacerbate many of the current threats to the long-term sustainable use of space. These threats include on-orbit crowding, radio-frequency interference, and the chances of an incident in space sparking or escalating geopolitical tensions on Earth. Michael K.

Acronym dictionary

This reference was originally compiled as a tool for abstracters who need to know the expansion of acronyms they may encounter in the texts they are analyzing. It is a general rule of abstracting at the NASA Center For Aerospace Information (CASI) that acronyms are expanded in the abstract to enhance both information content and searchability. Over the last 22 years, abstracters at CASI have recorded acronyms and their expansions as they were encountered in documents. This is therefore an ad-hoc reference, rather than a systematic collection of all acronyms related to aerospace science and technology

A Study of Types of Sensors used in Remote Sensing

Of late, the science of Remote Sensing has been gaining a lot of interest and attention due to its wide variety of applications. Remotely sensed data can be used in various fields such as medicine, agriculture, engineering, weather forecasting, military tactics, disaster management etc. only to name a few. This article presents a study of the two categories of sensors namely optical and microwave which are used for remotely sensing the occurrence of disasters such as earthquakes, floods, landslides, avalanches, tropical cyclones and suspicious movements. The remotely sensed data acquired either through satellites or through ground based- synthetic aperture radar systems could be used to avert or mitigate a disaster or to perform a post-disaster analysis
