Description

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 hundred two in 2025.
The design and requirements verification of our satellites requires of a high standard technological engineering flow and the use of complex simulation tools, commercial and in house tools.
Satellogic have been development a process of satellites thermal design and its verification based in the use of Space System Thermal analysis tool, internal tools and a Verification and Validation Plan that is executed in orbit, development this own concept to use a satellite as a flight thermal model (FTM).
The capability to use the space as a big laboratory gives to Satellogic an strong capability to improve the thermal design and technology push of our satellites with a constant feedback of flight information, given us reliability and low cost of test compare with the space standard industry.
The purpose of this presentation is to present the Satellogic thermal design flow, made up by thermal, analysis cases and FEM requirements definition, power condition sequence and orbit maneuvers generation tools. Finally a presentation in detail about the results of the satellite thermal design verification and validation strategy using a satellite as a Flight thermal model (FTM) and the Maya thermal correlation tool will be presented.
All the design flow is based on the use of a Space System Thermal as a thermal analysis and design verification tool.
