Within the last years, a larger number of spacecraft have been launched in Low Earth Orbit (LEO). The current trends show that it is continuously increasing, with a growing part for light CubeSats. Most of the LEO spacecraft are dedicated to Earth observation, and they can feature relatively large instrument openings and/or low thermal inertia, especially for the CubeSats. This usually makes...
Thermal analysis of hyperspectral optical instrument with emphasis on electronics heat dissipation
Thermal behavior of any optical instrument requires thorough analysis – either to prevent it from negatively affecting optical properties or to ensure operations safety.
An under development hyperspectral imaging optical instrument (OI) designed to Intuition-1 nanosatellite was subdued...
Satellogic is a company that produce satellite earth observation images. Looking for making Earth Observation imagery accessible and affordable to drive better global decision-making.
The Satellogic satellite earth observation constellation is currently made up for twenty six operative satellites and planned to growth to sixty three satellites in 2023, one hundred thirty nine in 2024 and two...
This year, the latest Long Term Support Version of Systema has been issued. The last active one was Systema 4.8.3P3, and it is now replaced by Systema 4.9.2.
The V4.9.2 version of Systema-Thermica has already been released and is available to users since September 2022. This new version provides some enhanced ergonomic features affecting the model creation process, such as choosing between...
Radian is a thermal analysis software conceived to provide agility to engineers, both at modelling and computing processes. Our software is accessible through a regular web browser and counts on a scalable network of computing resources in the cloud. Thermal analyses are supported by the Databank, a catalogue of satellite components, materials, surface treatments, orbits, and attitude...
Airbus Systema-Thermica is widely used in the European Space sector for thermal design and analysis for years. This presentation provides a brief look into the thermal processes for system level thermal analysis encompassing geometry building, thermo-physical and optical properties definition, TMM generation, and environment definition. In this presentation we address the modelling approaches...
ESATAN-TMS provides an advanced thermal modelling environment for the thermal analysis of spacecraft and launch vehicles. The thermal suite is continually being enhanced to meet current and future requirements of space projects, and to support the specific needs of thermal engineers.
A major focus of ESATAN-TMS development this year has been on providing facilities within Workbench to further...
For miniaturized thermal systems or thermal systems with limited energy, the harnesses heat leaks can be the major concern both for flight or test harnesses. In this frame, and based on test results, a methodology has been identified to adopt an appropriated reduced thermal modelling of the harness taking into account both conductive and radiative heat transfers. The actual aim is to provide...
Spacecraft thermal management is a complex endeavour that requires expertise from many different domains and employs several different strategies. Heat pipes are a common device used to move thermal energy from one part of the system to another. Modeling heat pipes can be very complex due to the inherent two-phase nature of the heat transfer. While systems-level models and correlations can be...
This work aims to provide thermal engineers a set of empirical equations between dust deposition rates and the modification of thermo-optical properties of radiators for lunar surface missions.
For the thermal engineer involved in the design of hardware dedicated to operating on the lunar surface, lunar dust is one of the biggest challenges. The smallest fraction of the sharp-edged small...
As the decommission of the International Space Station approaches, all eyes are set to the Moon as the next scientific hub for space exploration. Under the Artemis program, partners all over the world are developing missions to collect data and prepare the return of humans on the surface.
To support efforts for thermal analysis of lunar space systems, a sizing thermal model of a lunar rover...
pySINAS is a python version of the SINAS tool that was developed by ESA in recent years. This tool is normally used to map temperatures from lumped parameter based thermal analysis results to a finite element model to calculate the structure’s thermo-elastic response. Since the development of the simplified python version of the tool, the number of pySINAS users has grown yet many have found...
Aerobraking manoeuvres make use of upper atmosphere passes to decelerate a spacecraft. While this technique can considerably reduce delta-v requirements and allow for increased S/C dry mass, aerobraking subjects external spacecraft surfaces to intense thermal loads. Detailed analysis of the spacecraft thermal behaviour is therefore critical to ensure effective braking manoeuvres while safely...
