Structures, Pointing, And Control Engineering Laboratory


Peripheral Pointing Architecture (PPA)

The SPACE telescope testbed is required to perform precision pointing while maintaining the parabolic shape of the primary mirror. In order to achieve pointing control of the testbed accurate to 2 arc sec, a Peripheral Pointing Architecture (PPA), has been designed to physically demonstrate telescope pointing. The PPA uses an assembly of six lasers to simulate the object of study.
