The Gooding algorithm is currently the most widely used angles-only method for estimating the orbit of a spacecraft. Two modifications to Gooding's angles-only initial orbit determination algorithm are presented. The first method is an extension to N measurements, whereas the state of the art algorithm is restricted to three measurements. The second modification is an optimization method which searches in the neighborhood of the output of the classical Gooding algorithm for a more optimal orbit estimation. The theory is developed and examples are given.
