Beyond Gravity is a leading supplier of high-performance pointing mechanisms for electric propulsion thrusters, also known as thruster gimbals. Thruster gimbals are increasingly being used on commercial satellite platforms and scientific spacecraft due to their fuel mass efficiency advantages.
Beyond Gravity's pointing mechanisms support electric propulsion thrusters in their nominal position during launch, by means of a dedicated hold-down and release mechanism if necessary. They also reduce the mechanical loads on the thrusters via dedicated damper elements. Upon its release, the thrusters can be tilted around two axes using two actuators, which drive the platform either via a strut-linkage around a spherical joint or a cross gimbal type arrangement. This allows for high-accuracy thruster orientation.
A third axis can be realized with a robotic arm deployment mechanism. This provides a larger pointing and deployment range, which can be useful for off-loading the momentum wheels needed for spacecraft stabilization.
