ACT’s representatives from SMCEL will be pleased to welcome you to booth: D1, Bengaluru Space Expo 2022. ACT’s R&D Manager Srujan Rokkam will be present at the booth. Please contact us to set up a meeting to discuss your project.



AUGUST 6–11, 2022

During the 36th Annual Small Satellite Conference, we will explore the realm of the possible and investigate key advancements for small satellite missions to truly become transformational scientific discovery tools beyond low Earth orbit.

ACT’s McKenzie Read, Spacecraft Thermal Analyst will present on Monday August 8th at 3:30PM MST in the DBH Presidents Hall.

Design for Thermal: Understanding and tackling thermal challenges in space

As processing power increases onboard small satellites, the need for thermal control is vital. An optimized thermal design can make all the difference in mission success. Join ACT’s McKenzie Read for a discussion on how to thread the needle between under design and overdesign. We’ll dive into smart requirements definition, agile design and analysis, and cost-effective hardware from our extensive product lineup: from tried-and-true technology with millions of flight hours to newer innovative thermal techniques that support high power, high heat flux, broad temperature ranges, and lunar night survival. Learn how ACT and its products and services can support your mission at all stages.
