Abstract
In the absence of disturbances, an Earth orbiting satellite will follow a Keplerian orbit, which is a regular ellipse with Earth at a focus. However, in reality, there are many additional factors such as gravity field irregularities, Earth magnetic field interactions with satellite magnetic residual and induced magnetic field, solar radiation pressure, the gravitational influence of other celestial bodies and atmospheric drag, which disturb satellite orbits and deflect them from the classic Kepler ellipse fixed in inertial space. Generally, these orbital disturbances are relatively minor over the short-term of a few orbits. However, for low Earth orbiting satellites, atmospheric drag is the dominant factor, causing a satellite to gradually lose altitude (orbital decay) and eventually enterer the dense lower layers of the Earth's atmosphere, where is burned up. Even for fairly high altitudes, this decay can be fairly rapid. This effect can also be used for planned destruction of defunct satellites so as not to add to the space debris problem. This study develops simple models and simulators for satellite atmospheric drag orbital decay prediction. The simulator can be used for satellite orbital decay assessment and studying its effects.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
