Abstract

fetched live from OpenAlex

The Cospas-Sarsat system was initially developed under a Memorandum of Understanding signed in 1979 by Canada, France, Russia and the USA to detect and locate potential survivors of an aircraft crash or maritime distress event. The system was first used operationally in September 9, 1982 with the rescue, in Canada, of three people from the crash of a light aircraft. Since 1982 the Cospas-Sarsat search and rescue satellite system has provided location information to rescue services searching for people in distress as a result of either an air plane crash, boat sinking or land-based emergency. It has been estimated that this worldwide satellite system has been responsible for assisting in saving of more than 14,250 lives during the 23 years of operation from 19822001 [1]. Unfortunately, the 121.5 MHz frequency band used in this system is being subjected to interference from sources such as consumer products, unauthorized communication devices, and industrial equipment. These interference sources have caused Cospas-Sarsat system false emergency reports. Recently, Canada has been experiencing numerous false alerts in some of its major cities. This paper presents the methodology for the characterisation of these interfering signals and examines the possible signal sources.

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.
