Besides thermal vacuum, vibration, and radio frequency testing, what other types of environmental testing can a satellite be expected to undergo during a spacecraft level program?
Additional spacecraft level testing consists primarily of mass properties measurements, ambient deployment tests, and acoustic testing. The DFL’s vertical axis measurement system (VAMS) is used to perform mass properies measurements that include moment of inertia, product of inertia, centre of gravity, and mass. Ambient deployment tests of the various spacecraft appendages are performed primarily in DFL’s highbay #3. The DFL has access to a number of different types of deployment rigs and fixtures for performing these delicate tasks. Finally, acoustic testing: although the facilities for reproducing the effect of acoustically induced vibration in spacecraft structures does not exist within the DFL proper, the DFL has ready access to and assists in the conduct of these tests at the National Research Council of Canada’s Aeroacoustic Test Facility.
