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.
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.
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.
