Investigations into the Scalability, Manufacturability and Accuracy of the HATTS Joint

We propose to further investigate, design, manufacture, operate and characterize the novel Hemispherical Anti‐Twist Tracking System (HATTS) with a focus on two typical fields of application: terrestrial use (e.g., for CPV applications, ca. 0.3m^3 and 20‐50kg) and space use (e.g., for articulated high‐ gain antennas, ca. 0.1m^3 and 1 kg). Fundamental to these two differing applications are the careful selection of materials employed in HATTS construction, the relative sizes of the components and their effect on its cost and operation, and the differing environmental requirements that may drive the designs’ performance (mass, speed, power, etc.) in different directions. Particular attention will be paid to cutting‐edge manufacturing techniques.
We will operate the HATTS in real‐world scenarios, analyze its tracking performance, characterize the effects of environmental contamination on it, and quantify its performance (e.g., wind loading, mechanism wear, payload accommodations, etc.) Particularly with regard to operating solar concentrators and/or satellite tracking stations in a desert environment, we would work with KACST and Saudi Universities to improve HATTS’ design for efficient and remote/unattended use in desert environments.
