Dynamics/Control of a Radio Telescope Receiver Supported by a Tethered Aerostat
Bibliographic record
Abstract
Canadian researchers have proposed a design for a new radio telescope consisting of an array of very large ree ectors. A largemultitethered aerostat will be used to support each ree ector’ s receiver. The length of each tether can be adjusted by ground-based winches, and active control is used to overcome the effects of wind turbulence on the aerostat. To aid in the system’ s mechanical and controller design, a computer model has been developed, including models of the tethers and the aerostat. Two types of aerostat have been considered: spherical and streamlined. A wind turbulence model is incorporated to provide disturbance to the system. Controllers are used to adjust the tether lengths based on feedback of the receiver’ s position. The model is used to optimize the control gains. We e nd that, with 50 kW available at each winch, it is possible to maintain the receiver’ s position within 85 cm of its desired location, even in the worst-case cone guration.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
