Thank you. That explains the factor of two discrepancy in our two evaluations for rotation rate.vasya said:look more closely on first picture in this thread. thruster has offset of 0.25m of y-piersing-through-the-center-of-mass axis
Linear momentum refers to the motion of an object in a straight line, while rotational momentum refers to the motion of an object around a fixed point. In satellite mechanics, linear momentum is important for determining the trajectory and velocity of a satellite, while rotational momentum is important for maintaining the orientation and stability of the satellite.
In satellite mechanics, linear momentum is conserved through the principle of conservation of angular momentum. This means that the total momentum of a satellite in orbit remains constant, even as it moves through different points in its orbit. This is due to the fact that there are no external forces acting on the satellite in space, so its momentum cannot change.
The rotational momentum of a satellite is affected by its mass, shape, and the distribution of its mass. A larger and more massive satellite will have a greater rotational momentum, while a satellite with an irregular shape or uneven mass distribution will have a more complex rotational momentum.
In satellite mechanics, rotational momentum plays a crucial role in the stability of a satellite. If the rotational momentum is too high, the satellite may experience unwanted tumbling or spinning, which can disrupt its orbit and functionality. Therefore, it is important for engineers to carefully design and control the rotational momentum of a satellite to ensure its stability.
Yes, satellite mechanics can be used to predict and correct orbital anomalies such as changes in orbit or unexpected movements. By analyzing the linear and rotational momentum of a satellite, engineers can identify the cause of the anomaly and make adjustments to the satellite's trajectory or orientation to correct it. This is crucial for maintaining the functionality and safety of satellites in orbit.
