Abstract
Celestial Geolocalization using a star tracker is a promising method to expand on the abilities of sun sensor based celestial navigation systems used by planetary rovers. Realizing this improvement requires developing methods to improve inclinometer accuracy, in this paper we examine methods for characterizing and calibration biaxial inclinometers with the goal of reaching an accuracy of 0.004° over a wide range of motion. We examine electrolytic and MEMS inclinometers and test a number of models found in literature that describe the relationship between the measurements and the inclinometer frame gravity vector. We compare these models to our own formulation and were able to successfully validate our projection model to better than the desired accuracy.

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
