Findings on Aerospace Research Reported by Investigators at Sapienza University (Drag balance Cubesat attitude motion effects on in-situ thermosphere density measurements)

By a News Reporter-Staff News Editor at Defense & Aerospace Week -- Fresh data on Aerospace Research are presented in a new report. According to news originating from Rome, Italy, by VerticalNews correspondents, research stated, "The dynamics of Cubesats carrying a drag balance instrument (DBI) for in situ atmosphere density measurements is analyzed. Atmospheric drag force is measured by the displacement of two light plates exposed to the incoming particle flow."

Our news journalists obtained a quote from the research from Sapienza University, "This system is well suited for a distributed sensor network in orbit, to get simultaneous in situ local (non orbit averaged) measurements in multiple positions and orbit heights, contributing to the development and validation of global atmosphere models. The implementation of the DBI leads to orbit normal pointing spinning two body system. The use of a spin-magnetic attitude control system is suggested, based only on magnetometer readings, contributing to making the system simple, inexpensive, and reliable. It is shown, by an averaging technique, that this system provides for orbit normal spin axis pointing. The effect of the coupling between the attitude dynamics and the DBI is evaluated, analyzing its frequency content and showing that no frequency components arise, affecting the DBI performance."

According to the news editors, the research concluded: "The analysis is confirmed by Monte Carlo numerical simulation results."
