Abstract
This paper involves a thruster hardware setup and Hardware-in-the-Loop (HITL) simulation. The hardware that was used in the simulation is a simple cold gas thruster, which was constructed out of a solenoid valve and a nozzle with N2 gas being fed through air tubing from a compressed tank. The thruster was tested to characterize its performance. The thruster characteristic like time to reach on state, consistency of maximum thrust in steady state, the time it takes to reach an off state, and the input pressure vs. thrust profile were examined. The simulation is comprised of a non-linear dynamic model of two spacecraft formation flying, a Fuzzy Logic controller used to control the relative motion of spacecraft in formation, and an actuator block to fire the thruster and read the thrust measurement. The whole process and results are further explained in the paper.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
