The ICCD speckle camera of the Astronomical Observatory R. M. Aller has already been used with the Spanish 1.2-m telescope and it is pending to be attached to the German 3.5-m telescope at Calar Alto Observatory (Almería, Spain). In recent years, almost three hundred double and multiple stars have been observed with this instrumentation. All these data are analyzed at the Astronomical Observatory R.. Aller and the angular separation and the position angle of each binary system is obtained with the corresponding uncertainty. Along with the whole set of previous measurements, we are able to calculate new orbits or improve the former one. These objectives are accomplished by using the Docobo's method to calculate the orbits of binary systems. As an outstanding result of these accurate orbits an the estimation of the mass for some systems with a special astrophysical interest are made.
