⟨Sewer Clown⟩ I'd rather ask for just bite hte bullet instead of not asking for help but..So this is on 'ECEF' mode, but when I switch modes, it looks rather normal..
<queqiao->
What's the cool reasonable explanation for this eye sore?
<queqiao->
⟨lpg⟩ the earth rotates
<queqiao->
⟨Sewer Clown⟩ To ECEF is based on the earth's rotation? Or at least its POV

⟨egg⟩ ⟪Sewer Clown⟫ I'd rather ask for just bite hte bullet […] ⮪ The Sun revolves around the Earth, which is fixed in the centre of the universe.

⟨ProtonEnjoyer⟩ ECEF is referencing the earth's surface perspective
<queqiao->
⟨ProtonEnjoyer⟩ by it's equator and rotation, etc.
<queqiao->
⟨ProtonEnjoyer⟩ While in orbit of the earth, if you hit ECEF you'll understand better
<queqiao->
⟨ProtonEnjoyer⟩ Kind of as if "one orbit you'll cross africa, next you'll cross moscow"

⟨leudaimon⟩ A good example is the bunch of diagrams of the predicted decay location of the long march 5 upper stage in the news the last couple gets

⟨Mayo⟩ ECEF should be used if you are trying to land somewhere

⟨(ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ ECEF is used when you are doing things that involve the Earth. These include ground station passes, Earth observation and imaging, launch and landing, etc.
<queqiao->
⟨(ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ In ECEF, a geostationary satellite is fixed and does not move. Hence the name geostationary.

⟨(ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ ECI is an inertial frame that you are probably used to by now since it's used in stock KSP. Orbits in ECI "look normal" (e.g. are Keplerian conics: circles, ellipses, hyperbolæ) since the frame is inertial and non-rotating
