Abstract

fetched live from OpenAlex

The paper presents an overview of the achievements of the Space Technology Research Vehicle (STRV) 1a&b micro satellite mission in geostationary transfer orbit (GTO). Launched in June 1994 as auxiliary passengers on an Ariane-4, the two satellites achieved their primary objectives of demonstrating new space technologies and techniques in a harsh radiation environment at low cost and in a short timescale. The follow-on mission: STRV 1c&d will also be designed and built by the UK Defence Research Agency at Farnborough and the mission is described in detail. The proposed science and technology pay load, sponsored by the UK Ministry of Defence, the UK Particle Physics and Astronomy Research Council, the US Ballistic Missile Defense Organisation, the US Air Force, the US Naval Research Laboratory, the European Space Agency, the Canadian Defence Research Establishment and the Canadian Space Agency, is also discussed. STRV 1c&d are currently scheduled to launch into GTO aboard an Ariane-5 towards the end of 1998 for a nominal one year mission.

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.
