Surviving Orbit the DIY Way (eBook, PDF)

Testing the Limits Your Satellite Can and Must Match

• Format: PDF

Produktbeschreibung

Is your picosatellite ready for launch? Can it withstand rocket thrusts and the vacuum of space? This do-it-yourself guide helps you conduct a series of hands-on tests designed to check your satellites readiness. Learn precisely what the craft and its electronic components must endure if theyre to function properly in Low Earth Orbit.The perfect follow-up to DIY Satellite Platforms (our primer for designing and building a picosatellite), this book also provides an overview of what space is like and how orbits work, enabling you to set up the launch and orbit support youll need.Go deep into the numbers that describe conditions your satellite will faceLearn how to mitigate the risks of radiation in the ionospherePick up enough formal systems engineering to understand what the tests are all aboutBuild a thermal vacuum chamber for mimicking environment of spaceSimulate the rocket launch by building and running a vibration shake testUse a homebuilt centrifuge to conduct high G-force testsGet guidelines on scheduling tests and choosing an appropriate lab or clean room
