How small satellites can change space science?

Article published by Journal of Aerospace Technology and Management presents a scenario analysis of smallsats and its correspondent launch vehicles. Smallsats are satellites whose wet mass is below 500 kg. These devices are now becoming a booming commercial market with several applications, to improve phone calls, internet and GPS signals around the world, among other services. Read More →

Study suggests computational model to predict air pollution after a rocket launching

The study suggests a new approach to predict major atmospheric pollutants emissions after a Satellite Launch Vehicle (SLV) launching, using a weather/air quality computational model. Propellant combustion may release a huge amount of hydrogen chloride (HCl), carbon monoxide (CO), carbon dioxide (CO2) and particulate matter, posing risk to the environment. Read More →

Study shows vulnerabilities of GPS-dependent systems to electromagnetic attacks

The study identifies the levels of jamming power and distance required to disable GPS-dependent systems such as cell phones, and those used in automotive and aeronautical applications. Open source software was used to analyze the data collected to identify vulnerabilities in these systems, as well as proper countermeasures to undertake. The results were published by the research team from the Brazilian Aeronautical Institute of Technology in the Journal of Aerospace Technology and Management. Read More →
