Test
Quality
assurance techniques ensure spacecraft quality
each
step along the way from design to launch, by verifying
that components and the spacecraft conform to engineering
data through progressive tests.
Quality
Assurance
Engineering
data
is prepared with drawings and specifications to
describe each spacecraft component. A component
is defined as a functional unit, such as an antenna
or battery. This data is presented at the Critical
Design Review (CDR).
Manufacturing
of components includes procuring and testing the
parts then assembling and testing the components.
Acceptance
tests
certify component workmanship.
Qualifying
components
involves functional testing and exposure to the
anticipated environment.
Integration
and test checks
the spacecraft mechanical assembly, functions and
resilience to environmental exposure.
