What about a statistical and weighted elements of fix applied to methods as Metcalf (Lagrange multiplier) and Watkins&Janiczek (matrices) using only, gha,dec and ho (true altitude of sight).
Unlike MPP (Most Probable Position) where azimuts and intercepts are known, the above methods does not compute azimuts and
intercepts and does not need an AP (Assumed Position) for three observed bodies and more.
I have no found any paper about this case, to get ellipse of confidence must use the Covariance matrix and other maths objects as eigenvalue an eigenvector.
