초록 ▼

A satellite embodying at least one surface intended mainly for exposure to solar radiation and extending away from the satellite in a predetermined direction (Y), an on-board computer having connected thereto an attitude sensing system, an orbit control system for imparting thrust to the satellite along predetermined axes, and an attitude control system. The satellite further embodies a device for controlling the tilt of the surface in parallel with a plurality of planes containing the predetermined direction; and, therefore, particularly in parallel with the plane of a solar panel forming the surface. The tilt control device is controlled by the on-board computer. The tilting can generate a moment of pitch or relocate the center of gravity onto the axis of the orbit control system.

대표청구항 ▼

An attitude control system for a satellite, said attitude control system comprising: a satellite having attitude stabilizing means for controlling said attitude about a pitch, yaw and roll axis while said satellite is in a geostationary orbit; an onboard computer mounted to said satellite, said attitude stabilizing means being in communication with said onboard computer; at least one surface member extending from said satellite in a first direction away from said satellite, said at least one surface member adapted to be exposed to solar radiation; orbit control means mounted to said satellite for applying to said satellite thrusts along said pitch, yaw and roll axis; said orbit control means further comprising thruster means symmetrically spaced about said pitch and yaw axis; said thruster means being inclined at a predetermined angle at least with respect to said pitch axis such that a resultant force vector of said thrusts generated by said thruster means is in a first resultant force direction; and moving means mounted to said satellite for moving said at lest one surface member with respect to said satellite whereby the movement of said at least one surface member causes the center of gravity of said satellite to shift from a first position to a second position such that said first resultant force direction of the vector generated by said thruster means acts through aid second position of said center of gravity.
