Abstract:
Disclosed is a method for controlling the attitude guidance of a satellite with respect to an orbital reference system including a velocity axis, an orbital axis, and a Nadir axis; the satellite moving in the direction of the velocity axis, the satellite including an optical instrument having an observation axis, a solar generator defining a functional surface having a normal, an attitude control device, and a control unit. The method includes a step ( 104 ) of transmitting guidance commands so as to direct the observation axis of the optical instrument towards regions to be imaged or to orient the normal to the functional surface in the direction of the solar radiation. The guidance commands are commands to rotate the satellite about the velocity axis only, the angle of rotation about the orbital axis and Nadir axis within the orbital reference system being kept substantially at zero.

Claim (Index 1):
Method for controlling the attitude guidance of a satellite ( 1 ) with respect to an orthogonal orbital reference system (OXYZ) comprising a velocity axis (X), an orbital axis (Y), and a Nadir axis (Z), along a portion of its orbit (A) around the Earth (T), said orbit portion (A) being illuminated by solar radiation; the satellite moving in the direction of the velocity axis (X), the satellite ( 1 ) comprising a main body ( 3 ), an optical instrument ( 2 ) having a fixed observation axis (V) relative to the main body ( 3 ), at least one solar generator ( 4 ) that is fixed relative to the main body ( 3 ) and defining a functional surface whose normal (N, Na, Nb) has at least one component perpendicular to the velocity axis (X), at least one attitude control device ( 100 ), and a control unit ( 102 ) connected to the attitude control device ( 100 ), said method comprising a first step ( 104 ) of transmitting guidance commands from the control unit ( 102 ) to the attitude control unit ( 100 ) in order to direct the observation axis (V) of the optical instrument towards the regions ( 7 ) to be imaged,\n wherein the method comprises a second step ( 104 ) of transmitting guidance commands from the control unit ( 102 ) to the attitude control unit ( 100 ) so as to orient the normal (N, Na, Nb) to the functional surface in the direction of the solar radiation, and wherein the guidance commands of the first and second steps are commands to rotate the satellite about the velocity axis (X) only, the angle of rotation about the orbital axis (Y) and the Nadir axis (Z) within the orbital reference system being kept substantially at zero.
