The S-star cluster in the Galactic center allows us to study the physics close to a supermassive black hole, including distinctive dynamical tests of general relativity. We aim at a new and practical method to investigate the relativistic orbits of stars in the gravitational field near Sgr A(*). We use a first-order postNewtonian approximation to calculate the stellar orbits with a broad range of periapse distance r(p) We present a method that employs the changes in orbital elements derived from elliptical fits to different sections of the orbit.
