Influência da solução da ambiguidade GPS na qualidade posicional do CSRS- PPP [PDF]

O Posicionamento por Ponto Preciso (PPP) evidencia-se como alternativa ao método de posicionamento relativo. Trata-se de um método que faz uso das órbitas precisas e correções dos relógios de várias fontes, requer, para que se alcance alta acurácia, que a maioria das fontes de erros seja considerada ou modelada.
