Earth’s gravity has shaped human beings over thousands of years. It was clear from the first extraterrestrial spaceflight entering orbit that microgravity, due to an object being in free fall, immediately affects human body functions because of the increase, reduction, or absence of gravity. … Read More →
Ionospheric scintillation monitoring networks contribute to Global Navigation Satellite System
The positioning and air navigation system using Global Navigation Satellite System (GNSS) is affected by ionospheric scintillations. To mitigate these effects, it is necessary to study the characteristics of these scintillations using data generated by scintillation monitor networks, in order to describe the main characteristics of these networks. … Read More →

Aircraft development under the Mass Properties Management perspective
Aircraft mass properties, such as weight, are established during aircraft conception. Those properties usually are subject to deviations during aircraft development, which leads to a reduction of the desired performance and rework in the development process. This study presents a proposal to reduce rework, keeping the planned performance, and resulting in higher project efficiency. … Read More →
