Abstract

fetched live from OpenAlex

The geomagnetic Lorentz force represents a propellantless means of altering a spacecraft’s orbit. This paper investigates the application of the Lorentz force to the control of spacecraft formations. A spacecraft formation flying system is determined to be not fully controllable with the Lorentz force alone, therefore additional control effort must be provided using thrusters. Several electromagnetic/thruster hybrid controllers are presented in this paper for the purpose of mitigating the effects of the J2 gravity perturbation on spacecraft formation geometry. Continuous thrust and impulsive thrust strategies are considered. It is shown that the majority of the required control effort can be realized with the Lorentz force; however, the ratio of electromagnetic actuation to thruster actuation is dependent on the formation’s orbit inclination.

Full frame distilled prediction

Teacher imitation

Not 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.
