Development of Deployable Antennas for Advanced Maritime Communications and Monitoring with Small Satellites
Bibliographic record
Abstract
NORSAT-2 is a 16-kilogram microsatellite designed, constructed and tested at the University of Toronto Space Flight Laboratory commissioned by the Norwegian Space Center. The spacecraft supports maritime safety and security using an Automatic Identification System ship tracking payload as well as the first space-based Very High Frequency Data Exchange System, considered to be the next generation of the Automatic Identification System.\nThis thesis describes the author's mechanical design contributions to the development of NORSAT-2. To enable payload operations, two unique deployable antennas - a monopole and a cross-Yagi - leveraging tape spring technology are presented. The designs were elaborated iteratively through deployment, communications, vibration and thermal vacuum test campaigns. A spacecraft structural design capable of accommodating the payloads was achieved. The antennas were successfully deployed following spacecraft launch, as confirmed through on-orbit imagery. Payload operations were conducted, demonstrating on-orbit ship tracking data reception and data transmission to a Norwegian vessel.

How this classification was reachedexpand
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.
