A partir del método de Gauss de determinación orbital, ofrecemos distintos métodos numéricos libres de derivadas que mejoran al método original diseñando una nueva familia de métodos de tipo Steffensen, de orden óptimo ...
A modified classical method for preliminary orbit determination is presented. In our proposal, the spread of the observations is considerably wider than in the original method, as well as the order of convergence of the ...
