How do Satellites work? | ICT #10

We live our lives knowing that many satellites orbit our planet everyday, and that they are helping us in several ways. You might be surprised to know that there are almost 4,900 satellites orbiting the earth. The most obvious questions that come to mind are: Why are these satellites in totally different orbits? How does a satellite carry out all of its functions? And, what are the components inside them, which help them to accomplish all of their allotted tasks? Let's explore the answers to all these questions in detail.

Yeah, he didn't stress much on satellite communication. He said it's not efficient because the wave has to travel a distance of 22000 miles but EM waves travels with the speed of light 🤔

[@ReflectiveLayerFilm]

@@lbmetei7596 The further the satellite is the weaker the signal will be be when it reaches earth. Also at that distance the delay is about 140 millisecond which may not be a big deal. But the signal may have to travel that distance up to 4 times. So that's more than half a sec of delay which is not good for real time communication such as gaming or voice.

[@Testequip]

@Walking Speech If it's pics of satellites from earth you looking for - well that's not going to be easy. Even with the best ground based optical telescopes. Satellites range in size from a Rubiks cube (cube sats) to the size of an SUV in the geosynchronous 36000km orbit. Trying to seem them through a telescope or a zoom lens of a camera is equivalent to observing an ant 2 miles away through a telescope. You ain't going to see it.

[@GyanerDisha]

Thank you for such a easy and best explanation 😊

[@LIOTBs]

It's a great video, but one thing, as a physicist there is one thing the has sneaked into the public vernacular that is not correct: There is no such thing as centrifical force. What they mean to say is: Centripetal = center seeking force (centri = center). Ex. Gravity Centrifugal = away from center force (fug = away). Ex. The velocity of the satellite

[@patrickthompson5513]

the velocity- either angular or linear- of the satellite is not away from the center. The linear velocity is tangential to the orbit. And for angular velocity, inwards/outwards it is meaningless. Gravitational force is the centripetal force. But yes centrifugal force is make believe.

[@NoName-ef3jq]

1:06 Hate to be the nerd here but, that is not true. Small air particles escape the atmosphere and all satellites hit these particles. This creates a very small amount of deceleration called "Orbital Decay". While this is a slow process, most satellites use RCS or Ion engines to counter this. Sorry for my nerd lesson, it was your fault for reading the entire thing. Also there are more reasons for orbital decay but, this was one of the more simple ones.

[@jakub.kubicek]

0:30 There ain't no centrifugal force. There's only a centripetal force: one that points inwards. In a satellite's case, this centripetal force is the gravitational pull. What keeps an orbiting satellite in orbit is the balance between its centripetal acceleration (caused by the centripetal force) and its lateral velocity with regard to whatever it's orbiting.

They are not refueled, the amount of fueled they carry is calculated beforehand in order to last for the entirety of its lifetime. Then, as it has been mentioned in the video, when the satellite is about to run out of fuel, they move it to the graveyard orbit and leave it there.

A waste of materials would be to go and refuel them, remember you have to launch a rocket to get to them so it is much better to just launch a new one. This obviously increases the amount of space debris up there and that's the main issue that needs to be solved.

[@bradnoyes7955]

0:38 sigh, again, there is no such thing as a centrifugal force. "Centrifugal Force" is a fictitious idea that is used to describe the apparent outward force on an object in radial motion. Centripetal force is the actual force that causes an object to travel in an arc and in this case, gravity is the centripetal force.

[@JaySmith91]

The centrifugal force appears in a rotating frame of reference. There is nothing wrong with considering the centrifugal force in rotational motion, because it's sometimes easier and more useful to choose a rotating frame. People go from being okay with it (high school) to hating it and crucifying those who mention it and saying (incorrectly) that there's "no such thing" (woke high school kids and undergrads) to being perfectly fine with the concept (engineering/physics graduates and professionals). Centrifugal force as a concept becomes useful in doing free body diagram at a fixed time point (i.e. turning a dynamics problem into a statics problem. Source: xkcd.com/123/
