Potencialidades do serviço on-line de Posicionamento por Ponto Preciso (CSRS-PPP) em aplicações geodésicas
Bibliographic record
Abstract
O metodo de Posicionamento por Ponto Preciso (PPP) com a utilizacao de GPS ( Global Positioning System ) vem se popularizando nos ultimos anos, principalmente, com o surgimento de servicos gratuitos e de processamento on-line , tais como, o Natural Resource Canada (NRCan), denominado Canadian Spatial Reference System – Precise Point Positioning (CSRS-PPP). Neste metodo, o posicionamento utiliza dados de somente um receptor e, fundamentalmente, requer apenas o uso de efemerides e correcoes dos relogios dos satelites precisos. Neste artigo, avaliou-se seu desempenho mediante a utilizacao de um longo periodo de dados (1.596 dias), obtidos na estacao POAL da Rede Brasileira de Monitoramento ContInuo (RBMC), localizada em Porto Alegre, RS, Brasil. A analise das series temporais das coordenadas diarias estimadas pelo CSRS-PPP mostraram discrepâncias de poucos centimetros, quando comparadas com os valores oficiais adotados para a estacao POAL. Palavras-chave: GPS, Posicionamento por Ponto Preciso (PPP), servicos on-line de PPP, CSRS-PPP.

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.
