Light-weight Self-correcting Inflatable/rigidizable Space Antennas, Phase I

Metadata Updated: May 2, 2019

The NASA/L'Garde Inflatable Antenna Experiment (IAE)flown in STS-77 has showed the potential of this class of structures in significantly reducing the costs for space access. It also pointed the way to future work. Numerous studies and ground tests on real hardware conducted by L'Garde since then, have shown the extension of these advantages to rigidizable parabolic reflectors and provided further proof for their manufacturability, their significant stowage volume advantages. and their controlled deployment. The most significant issue that remains is their surface accuracy under the influence of, mainly, thermal loads. The structural films laminates that must be used in their construction exhibit positive thermal expansion coefficients adversely affecting their accuracy in the frequency range >1-3 GHz. In Phase 1 of this effort L'Garde and SARA intend to design and analyze a corrective system for inflatable and/or rigidizable antennas comprised of a phased array feed capable of correcting phase errors and a movable feed platform to correct for focal point shifts. If the corrective system feasibility is proven and we proceed to Phase 2, such a system will be designed, built and tested on a subscale inflatable or rigidizable reflector. This system can have profound positive effects on space communications.
