Abstract

fetched live from OpenAlex

An integrity checking system (ICS) for satellite telemetry is described. The integrity of satellite telemetry is defined in terms of relevance, correctness, completeness, and confidence. The relevance factor provides the basis for partitioning the telemetry data set into relevant and irrelevant data for current processing needs. This in turn enables a satellite monitoring system to vary the amount of data according to the load on the system. The correctness factor deals with the accuracy as well as the timeliness of telemetry data. The detection error conditions in satellite system control originate from analysis of telemetry. The completeness factor in assessing the integrity of telemetry data makes it possible to choose a representative set of available data for analysis. This factor takes precedence over the relevance factor whenever a satellite exhibits anomalous behavior such as uncontrollable spin, or component failures. The confidence factor determines the data sampling rate. That is, in normal satellite monitoring, the sampling rate may be longer than in a crisis situation where more data may be needed for error correction.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
