SOLAR SYSTEM

Detailed explanation-1: -The attitude of a satellite refers to its orientation in space. Attitude control of a satellite refers to the maintenance of the satellite stability at its assigned position. Attitude control is necessary to keep the antenna pointed towards the desired region on the surface of the earth.

Detailed explanation-2: -The attitude of a satellite is its position in space-its orientation. Attitude determines what a satellite looks at-which way its cameras are facing, and the angle the satellite makes with the object it is orbiting.

Detailed explanation-3: -When NASA scientists or engineers talk about attitude, they mean the way that the ship is positioned in 3-dimensional space. Attitude is in effect, the way that the ship is “pointed.” In order for the ship to go in the right direction, attitude must be monitored and controlled.

Detailed explanation-4: -Altitude and Orbit Control (AOC) subsystem consists of rocket motors, which are capable of placing the satellite into the right orbit, whenever it is deviated from the respective orbit. AOC subsystem is helpful in order to make the antennas, which are of narrow beam type points towards earth.

Detailed explanation-5: -Satellite attitude control systems are divided into two categories-passive and active control systems. The various elements which contribute to each type of system are discussed.

Detailed explanation-6: -Passive Magnetic Attitude Control (PMAC) aligns a CubeSat to within ±15◦ of the Earth’s local magnetic field line throughout each orbit, maximizing particle counts available for onboard science instrumentation.

Detailed explanation-7: -Methods used to generate active control torques include momentum wheels, electromagnetic coils, and mass expulsion devices, such as gas jets and ion thrusters. The three axes which define a satellite’s attitude are its roll, pitch, and yaw (RPY) axes.
