Simulations and ResultsInter Satellite LinksFigure 6-14 Visibility of Galileo Option 1 Constellation6.1.1.8 Galileo 2 (GEO/MEO)The second option for Galileo is a mixed constellation, consisting of a MEO 27/3/1 Walkerconstellation and three GEO. The MEOs have an inclination of 56° and an orbit altitude of19424 km, the GEOs are located at 10°W, 10°E and 30°E. The following picture shows theground tracks and S/V positions, as well as the station locations of the proposed groundnetwork.Page 104R. Wolf
