Paper examines feasibility of scientific earth satellite that is guided in drag-free orbit by shielded, free-falling proof mass and some of applications of scheme; control and guidance system is analyzed with respect to system performance and gas usage requirements; trajectory errors, due to vehicle gravity, stray electric and magnetic fields, and sensor forces are investigated; it is found that drag and solar radiation pressure forces may be effectively reduced by three to five orders of magnitude for 100- to 500-mi orbits and that deviation from purely-gravitational orbit may be made as small as 1 m/yr; satellite could be used to make precise measurements in geodesy and aeronomy.
