Project Description

Structural Dynamics Test of Spiral Tube Actuator for Controlled Extension / Retraction (STACER) Antenna Deployment in Microgravity
The Trapped Energetic Radiation Satellite (TERSat) is an MIT satellite program sponsored by the AFRL University Nanosatellite program. The goal of TERSat is to understand how Very Low Frequency (VLF) waves interact with radiation particles and how VLF waves propagate in the plasma environment of the Van Allen Radiation Belts. A key component of TERSat payload is the STACER (Spiral Tube & Actuator for Controlled Extension/Retraction) antenna that will be used to transmit and receive VLF signals. A microgravity environment on a parabolic flight would enable testing of the deployment mechanism and antenna dynamics under flight- like load conditions, adding confidence in the STACER deployment system design.
