KASCADE GRANDE is an extension of the KASCADE experiment to measure high-energetic air showers in the energy region of 10¹⁶ eV to 10¹⁸ eV. Different algorithms have been performed to estimate the main EAS observables at the Experiment; these offer the possibility to calculate the position of the shower core, the zenithal and azimuthal angles of the shower axis and the integrated number of charged particles at the detection level. Additionally muonic and hadronic observables of the original KASCADE experiment are at disposal for each single event. CORSIKA simulations at high energies have been used for preliminary optimisation of the algorithms. By including them in the designated code for the shower event reconstruction the algorithms have been combined with the full KASCADE GRANDE detector response simulation.
