2016年8月8日 · Launch azimuth is constrained at the Cape between 35 and 120 degrees due to land mass overflight restrictions. All launches from Cape Canaveral are therefore restricted in inclination between 28.5 and 59 degrees." So what I don't understand is how the orbital inclination is calculated knowing the azimuth. $\endgroup$ –

2020年1月13日 · If the launch site was on the equator, it's not difficult to imagine that if you launch exactly due East, i.e. tangential to the target orbit, the orbital plane is coincident with the equatorial plane, so your orbital inclination equals the latitude of your launch location: 0 degrees. But as your launch location moves away from the equation ...

2017年6月6日 · Yes. While you can change your inclination over a burn, in a classic "plain" launch your starting latitude is the inclination peaks where your orbit is directly above them relative to the launch site location.

2021年3月9日 · The idea is that inclined orbits spend most of their time above latitudes that are near their inclination. Let's say you can talk with a Starlink satellite as long as it's 30° above the horizon. A 60° degree half-angle cone from a satellite 400 km above the Earth has a radius of 700 km, which is about +/- 6° in latitude.

2019年8月15日 · Consider a transfer between two circular orbits of similar radius, the only difference being the inclination difference, $\alpha$. What's the minimal $\Delta v$ required to perform this transfer? Inclination change strategies I have considered so far: A single burn inclination change.

2019年3月26日 · Normally inclination is kept between 0 and 180 deg since, as you hint yourself, it is the angle of the orbital plane wrt the reference plane (e.g. equator) at the ascending node. Mathematically speaking and without knowing the context, I would think the same as you, that a negative inclination somehow is supposed to indicate the ascending node ...

2020年7月21日 · $\begingroup$ @RossPresser You could burn elsewhere to raise the ascending/descending node, then do the inclination-change burn at the higher AN/DN, and do a final burn to return to the original orbital altitude. For large inclination changes when the AN/DN is low, this can be more efficient than just going straight for the inclination change ...

Yes, it is possible to determine the orbital inclination from the Longitude of the Ascending Node, and a position vector that is not the Ascending node or the Descending Node, because both the ascending node and your position are points in the orbital plane, and the vectors pointing to each from the body being orbited uniquely define that plane.

2019年7月6日 · The latitude of a launch site determines the minimum inclination that can be directly reached; launching from 28.5º latitude in the due-East direction achieves a 28.5º orbital inclination. Launching to any higher inclination is straightforward, simply by steering continuously North-of-East during the ascent.

2024年2月12日 · "a" is desired inclination change "b" is optimum thrust direction. Blue vector is the thrust vector to achieve red orbit inclination "a" without affecting scalar velocity or apoapsis. Purple vector is the thrust vector at right angle to the green orbit needed to achieve desired new orbital inclination "a".
