Question: 1 / 400

Which system is critical for maintaining the trajectory of a satellite?

Solar Power System

Navigation Guidance Control System (NGC)

The Navigation Guidance Control System (NGC) is essential for maintaining the trajectory of a satellite. This system is responsible for determining the satellite's current position and velocity, as well as calculating the necessary adjustments needed to keep it on the correct path. The NGC utilizes various algorithms and data inputs, such as GPS signals or onboard sensors, to navigate effectively in orbit.

Moreover, the NGC can manage the orientation and thrust of the satellite, enabling it to perform maneuvers that are crucial for trajectory correction. This ensures that the satellite can fulfill its mission objectives, whether that involves communication, observation, or scientific research. The precision and accuracy of the NGC are vital for tasks such as orbit insertion, station-keeping, and any required orbital transfers, reinforcing its critical role in satellite operations.
