轨道根数的英文怎么说?
<1>轨道根数的英文怎么说?1> Orbital root numbers refer to the different numbers assigned to orbits of a spacecraft depending on its orbital characteristics. They make it easier to identify different orbits and track their changes over time. Orbit root numbers are designated by the two primary orbital parameters of a spacecraft: inclination, or angle of inclination relative to the equatorial plane, and mean anomaly, or the angle of a spacecraft’s position relative to its perigee (the point at which it is closest to the ast earth). Each combination of varying orbit parameters, such as inclination and mean anomaly, produces a unique orbit root number. 您可能还想了解: 操组词大全|操组词详解 糙组词大全|糙组词详解 舱组词大全|舱组词详解 An orbit root number is assigned for a particular mission based on the orbit parameters at launch. As the spacecraft travels its orbit, these orbital parameters are continuously changing, resulting in the orbit’s orbital root number changing too. Every time the spacecraft orbits the Earth, its orbit root number is updated to reflect the changing parameters of its orbit. Tracking a spacecraft’s current orbit root number helps mission controllers to accurately predict its trajectory. Armed with this knowledge, mission controllers have the ability to more effectively respond to any changes in a spacecraft’s parameters. Orbit root numbers are widely used by mission controllers to keep track of their spacecraft’s present movements. For a spacecraft to remain in a particular orbit, its inclinations and mean anomaly must remain the same or they will cause the spacecraft’s orbit root number to change, resulting in the spacecraft’s movement to a new orbit. Orbit root numbers are also extremely helpful for spacecrafts that may have been launched simultaneously but into different orbits. By tracking their respective orbit root numbers mission controllers can identify which spacecraft is in which particular orbit. The primary benefit of orbit root numbers is that they provide an easy way to identify, describe, and track the changing orbits of inpidual spacecraft. They allow mission controllers to more easily observe changes in their spacecraft’s orbital parameters, better allowing them to predict the trajectory of their spacecraft and more effectively respond to any changes that may happen. |
