Third day at #AIAS2024! In a short while, our colleague Giovanni Lombardi will be presenting our study titled "?????? ?????????????? ???????????? ???? ?????? ?????????????? ?????????? ?????????????????????? (????????) ?????? ?????????? ?????????????? ?????? ?????????? ???????????? ??-?????? ??????????????????????." ?? The CUSP project is a CubeSat mission designed to measure the linear polarization of solar flares in the hard X-ray band using a Compton scattering polarimeter. This innovative mission will help us explore magnetic reconnection and particle acceleration in the flaring magnetic structures of the Sun. ?? CUSP is part of the Italian Space Agency's Alcor Program, aimed at developing new CubeSat missions. Currently, CUSP is approved for a Phase B study. ???? ???????? ????????????????????????, ????’???? ?????????? ???????? ???? ?????? ?????? ???????????? ?????????????????? ?????? ?????? ??????????????, ?????????????????? ??????????-???????????????? ????????????, ?????????????? ????????????????, ?????????????? ??????????????????????, ????????????/?????????????? ???????????? ?????????????? ????????????????, ?????? ???????????????? ???????????????????????? ???? ?????? ????????????????????. ?? ???? ??????'???? ???? ????????????, ??????'?? ???????? ????! https://lnkd.in/ebCVy83W #SpaceWeather #CubeSat #XRayPolarimetry #SolarFlares #SpaceScience #AIAS #CUSP #ItalianSpaceAgency #simulation #rbf

Dynamics and FNTSM control of Spacecraft with a Film Capture Pocket System The research involves the development of a fast nonsingular terminal sliding mode controller (FNTSM) and a fixed time dilation observer (FxESO) integrated into an attitude-tracking control law. The effectiveness of the controller is validated through the establishment of a virtual prototype. This research provides theoretical support for the future in-orbit application of the system.

?? Vacuum solutions for space – Thermal vacuum chambers (TVAC)??? TVACs allow scientists and engineers to test the resilience of each component used in satellites against the harsh conditions they will encounter in space. These include extreme variances in temperature (between 70K and 400K), as well as irradiation. Each TVAC comes preconfigured with a fore-vacuum pump, turbomolecular pump, and thermal shroud and is designed to deliver turnkey functionality to space research functions.

#Article ?? Dynamic Modeling and Attitude–Vibration Cooperative Control for a Large-Scale Flexible Spacecraft by Guiqin He and Dengqing Cao ?? https://lnkd.in/gYDaYedN MDPI; Harbin Institute of Technology #largescaleflexiblespacecraft #attitudemaneuvering #cooperativecontrol #Abstract Modern spacecraft usually have larger and more flexible appendages whose vibration becomes more and more prominent, and it has a great influence on the precision of spacecraft attitude. Therefore, the cooperative control of attitude maneuvering and structural vibration of the system has become a significant issue in the spacecraft design process. We developed a low-dimensional and high-precision mathematical model for a large-scale flexible spacecraft (LSFS) equipped with a pair of hinged solar arrays in this paper. The analytic global modes are used to obtain the rigid–flexible coupling discrete dynamic model, and the governing equations with multiple DOFs for the system are derived by using the Hamiltonian principle. The rigid–flexible coupled oscillating responses of LSFS under the three-axis attitude-driving torque pulse during the in-orbit attitude maneuvering process are investigated. A study on the flexibility of the hinge was also conducted. Based on the simplified and accurate dynamic model of the system, we can obtain a state-space model for LSFS conveniently, and the cooperative control schemes for rigid motion and flexible oscillation control are designed by using the LQR, PD, and PD + IS algorithms.

Everybody knows that a turnkey solution saves you the trouble of getting everything assembled, tested and ready to go like buying a new car. ?? When you buy a new car you want it ready to drive. ???? Why not use the same logic for your new Thermal Vacuum Chamber? ?? Simulate space environment with the turn of a key. ????? #TVAC #Spacesimulation #Vacuum #Chamber #Leybold #LeyboldVibe
