How Do Satellites Stay in Place? | In Orbit | BBC Earth Science

For Satellites to work most of them need to stay in one place. So you may think it's simple, the satellite needs to spin at the same pace as Earth. But nothing is ever that easy, because if a satellite was to spin at Earth's rotational speed it would crash back down into Earth.

How the thousands of satellites orbiting the Earth have transformed the modern world.

Nicely done! I have seen many explanations of geosynchronous orbit, but I basically had to figure it out for myself (decades ago). I hope this woman keeps making videos like this because this one was great!

Idk why This question randomly popped in my head but thanks for this video !

[tinytonymaloney]

I think this lady is brilliant at explaining stuff.
I already knew this but i just love listening to her, she makes stuff interesting.

[khadimhussain]

You teach very well, I like you but I like you

This only works for signals, but if you want to point a camera down at Earth, you can only keep it stationary on one spot, at the equator.

I consider gravity as a myth, and to change your vector in space without thrusters, and how can you do this in a vacuum. You can’t and how did you get past the firmament, and what about the Van Allen belt, you got a lot of explaining to do Lucy !

[j-dubtheOG]

Then why the need to hide all those fiberoptic lines under oceans???

[Drizzyixx]

Hey you. Yeah you. If you're reading this hope all is well and have a great day please 🤗

Should be noted this video is only about geosynchronous satellites which is a tiny percentage of satellites.

[shaunridley]

That makes no sense. You can’t keep up being that close but further away you can?? The further away, the more you have to travel now? But apparently they say because it’s less gravity, the satellite goes faster hahaha

[neilknightley]

She talks like Boris and with force haahah

The earth is not spinning. It is stable.

[seanle]

Magical points has to be perfect..no more no less..just perfect

[Sannidor]

ISS however flies with speed of 7.66 km/h and it's "always falling" 🤡
isn't scienceTM amazing?

Sorry, this does not explain how a satellite stays in a geocentric orbit. The earth spins at a speed between 1000 and 67000 mph depending upon location. The satellite is 300 to 1000 miles above the earth, it must travel at a speed much faster than the rotation of the earth below it. While gravity may be weak at that distance, it still has a drag effect. So by what means does the satellite propel itself through space to keep its geocentric position.

Now the next query, the earth has a 23.5 degree tilt at its axis. Each 365.25 days that tilt will vary 47 degrees from the winter to summer solstice. By what means does the satellite adjust to the constant movement of the axis tilt?

Once on a plane I met a person who worked in the industry and he had no answers for these questions, his only reply was “that’s not the department I work in”.

Consider the following:
a. Numbers: Modern science does not even know how numbers and certain mathematical constants exist for math to do what math does. (And nobody as of yet has been able to show me how numbers and certain mathematical constants can come from the Standard Model Of Particle Physics).

b. Space: Modern science does not even know what 'space' actually is nor how it could actually expand.

c. Time: Modern science does not even know what 'time' actually is nor how it could actually vary.

d. Gravity: Modern science does not even know what 'gravity' actually is nor how gravity actually does what it appears to do.

e. Speed of Light: 'Speed', distance divided by time, distance being two points in space with space between those two points. But yet, here again, modern science does not even know what space and time actually are that makes up 'speed' and they also claim that space can expand and time can vary, so how could they truly know even what the speed of light actually is that they utilize in many of the formulas? Speed of light should also vary depending upon what space and time it was in. And if the speed of light can vary in space and time, how then do far away astronomical observations actually work that are based upon light and the speed of light that could vary in actual reality?

[LawfulRebelTV]

BUT A GEOSTATIONARY ORBIT IS ONLY POSSIBLE AT THE EQUATOR. AND THEN, WHAT IS THE FUEL INPUT AND PROPULSION TO MAINTAIN ORBITAL SPEED? WHAT PROVIDES THE PUSH?

[TerenceHughes]

I'm more curious to know how satellites survive in space given the fact that the melting points of the metals used are far lower than the temperature in the "thermosphere" where they supposedly are.

Earth doesn’t rotate and satellites are on balloons! !!
