Futhermore problems of the error of astro gravimetric leveling and the nonlinear influence are discussed.

This idea is very novel and only our company has the patent. It was avoid human error in manual leveling, save the time and really did it once and for all.
To eliminate the influence of nonlinear error of PSD on the measurement scale and accuracy of laser leveling tester, a new method of Radical Basis Function (RBF) neural network was used.
