Calculate the delta-V budget for the DIRECTV 15 propulsion system, after it has already been inserted into its operational orbit. DIRECTV is a GEO spacecraft at 0° inclination, 100° West longitude, and 35,792 km altitude (orbit velocity of 3.07 km/s). The satellite has a mass of 6,200 kg and an approximate area of 225 m^2. Assuming worst case values, a disposal orbit of 300 km above the operating altitude after 15 years, and that the solar radiation pressure is not considered for the propulsion system, the delta-V budget for the spacecraft is _______ m/s.
