Altitude and Orbit control

1. A ltitude And Orbit Control Mrs.R.Krishnaveni

2. Introduction 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.

3. Satellite Orbits Overview Satellites undergo an elliptical orbit around the Earth . The shape and size of ellipse can be defined by i) eccentricity ( e ): degree of perturbation from the perfect circle ii) the semi-major angle ( a ): the half distance between the perigee and apogee in the ellipse.

4. Altitude Control and Orbit Control The Attitude and Orbit Control System provides three-axis stabilized Earth-pointing attitude control during all mission modes and measures spacecraft rates and orbital position .

5. Altitude Control Methods Thrusters Magnetic Torquers Gravity Gradient Stabilization

6. Orbit Control Methods Propellant-Based Maneuvers Electric Propulsion Reaction Wheels

7. Challenges in Altitude and Orbit Control Fuel consumption Space debris Environmental factors

8. Benefits of Altitude and Orbit Control The Attitude and Orbit Control System provides three-axis stabilized Earth-pointing attitude control during all mission modes and measures spacecraft rates and orbital position .

9. Real-World Applications Earth observation Global positioning systems (GPS) Satellite TV and internet

10. Future Trends The 'Satellite Attitude and Orbit Control System Market' continues to adapt to shifting consumer demands and corporate needs, thus the forecast is still positive. The market is expected to experience significant expansion between 2023 and 2030 with increased investment and strategic alliances .
