Abstract
The design of attitude determination and control of nanosatellites requires innovative solutions that are low-cost, small in size, and minimized power consumption. The University of Manitoba T-Sat1 project has created a simple complement of sensors and actuators that can provide stable determination and orientation. The linear region of photodiode readings was combined with magnetometer readings in a sensor-fusion attitude determination algorithm. The actuators were custom-built torque discs on printed circuit boards that proved easy to mount and generate fields 25 nT that are sufficient to orient the satellite while in orbit. The torque disc manufacturing process is described with details on the imperfections and lessons learned from the prototypes. This paper describes the hardware and software design and implementation for the attitude determination and control of the T-Sat1 nanosatellite.

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
