Geostationary orbit satellites sizes and mass

The first step is to examine a number of geostationary orbit (GSO) satellites from the open literature and determine a representative reference value. The goal is to generate a ''reference GSO satellite'' that is heavy enough to represent future satellites and provide a reasonable estimate of the orbital propellant required. Table 5.5 gives the dimensions of the satellite main body, with all antennas folded. The mass ratio determined by the ''beginning-of-life'' mass and the ''empty'' mass is the propellant required for maintaining the GSO orbit and station-keeping due to orbital precession.

Referring to Aviation Week and Space Technology of 31 October 2003, the cover has a picture of the Boeing Satellite Systems 601B for broadcast and broadband multimedia services. This is not unlike the reference satellite in Table 5.5. Given a reference satellite, how much propellant is required to change its altitude and orbital inclination?
