POSICIONAMENTO RELATIVO COMBINANDO AS OBSERVÁVEIS GPS E SBAS
Bibliographic record
Abstract
O sistema SBAS fornece aos seus usuarios, em tempo real, informacoes de acuracia e integridade, atraves das correcoes diferenciais que sao transmitidas pelos satelites geoestacionarios. Este sistema esta disponivel em regioes especificas do globo terrestre, dentre elas: Estados Unidos, Canada e Europa. No Brasil este sinal e transmitido na mesma frequencia L1 do sistema GPS, porem nao em tempo real, mas atraves de um protocolo chamado MT27 e alguns receptores possuem canais de frequencia especifica que captam estes sinais, com a promessa de que estes dados melhoram as condicoes do rastreio e a precisao das coordenadas. Utilizou-se a observavel fase da onda portadora (L1) para inferir sobre a sua contribuicao para o posicionamento. Os dados dos satelites SBAS foram processados e analisados conjuntamente (GPS+SBAS) e separadamente (apenas GPS); assim podem-se comparar as coordenadas e analisar a contribuicao que os dados SBAS produzem no posicionamento, em bases curtas (ate 10 km), utilizando-se de posicionamento relativo.

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; both teacher heads agree on what is shown here.
