The correct option pertains to the responsibility of satellite systems in maintaining a satellite's intended orbit. The function described is accurately fulfilled by systems that control the satellite's path and adjust its trajectory as needed.

The Navigation Guidance Control (NGC) system plays a vital role in this context. It is responsible for calculating the required maneuvers to ensure that the satellite remains in its designated orbit, which includes handling both position and movement adjustments based on external influences like gravitational forces and atmospheric drag.

While the other systems have essential roles, they do not primarily focus on orbit maintenance. The Attitude Determination and Control System (ADCS) manages the orientation of the satellite, while the Onboard Computer System (OCS) handles data processing and command execution. The Attitude Control System (ACS) similarly pertains to maintaining proper orientation rather than orbital position. Thus, the NGC is distinctly tasked with managing the satellite's movement through space to achieve and maintain its intended orbit.
