Excellent and easy way of explanation, many doubts have been clarified! Thanks alot for your great work.
Thanks mam naku ee roje telisindi miru s&t start chesaru ani thanks for this support
Waw mam no one can teach like that... please continue this lecture series ....
Best explanation after searching a lot all of my doubt are cleared after see this....thank u soooo much mam....
Ma'am best and easiest explanation that I have ever heard
Thanks ma'am
Excellent mam.
nice mam you are amazing teacher
crystal Clear and best explanation.......! Thank u madam.....!
Best explained by u
On what basis the orbits are classified mam which is that are they classified based on orientation ?
Thank you
Thanks alot mam.. 😊😊
Thank you very much for the video madam 🙏
Chala Baga chepparu mam....👍👍👍
Very nicely explained Mam
Mam, Can you please explain about the Sun Synchronous Orbit ?
A Sun-synchronous orbit matches the rate at which the Earth goes around the Sun. It is a low-Earth orbit.
Advantage: consistent lighting conditions of the Earth’s surface enable us to compare images from the same season over several years
Altitude: typically 600-800 km
Satellite period: 96-100 minutes
Satellite examples: Landsat 7, CloudSat
Transcript
Dr Allan McInnes
Sun-synchronous orbit is a special kind of orbit. Wow, this is where we get into the complexities or orbit mechanics. So orbits are not fixed in space, they tend to change over time, and one of the things that makes an orbit change is the shape of the Earth. And in the case of the shape of the Earth, one of the changes that we see with orbits is something called precession of the orbit, and precession basically means that the orbit moves relative to the Earth over time. So you’re not just orbiting around the Earth - the circle of the orbit is actually shifting in space as well.
Normally that’s something that we either ignore or counter the effects of by manoeuvring the spacecraft. But with a Sun-synchronous orbit, what we actually try to do is take advantage of that. If we pick the right altitude and the right inclination relative to the equator, we can actually get a precession rate at which that orbit changes that just happens to exactly match the rate at which the Earth goes around the Sun.
And what that means is that, if we put a spacecraft into an orbit where, when it initially takes off and is flying around the Earth, it spends part of its time directly over a point that’s seeing midday Sun and the other half of its orbit over the side of the Earth where it’s exactly at midnight, we’re going to maintain that all the way through the year, because as the Earth moves around the Sun, the orbit’s also shifting. If we weren’t in a Sun-synchronous orbit, then we might start out seeing noon and midnight and then later in the year we’d be seeing some other time of day, and it would change over time.
With the Sun-synchronous orbit, we’re locked to the Sun essentially, and so if we start out seeing noon and midnight, we’ll always see noon and midnight. And that can be quite useful for observation and scientific missions where we want to get consistent lighting conditions on the ground. So if we always want to be over something with nice bright midday Sun then we’ll make sure we always see that with the Sun-synchronous orbit.
Wow so nicely explained mam , thanks a lot mam
Crystal clear explanation ... thanks mam
Nice Explanation madam, i am from Ethiopia
What is Sun Synchronous Polar Orbit??
Make a video on this regarding.... Please
Very simple and nice explanation🙏🙏🙏
What is the meaning of Zenith location mam ?
what is the need of geosynchronous orbit
Very nice explanation Ma'am thank you.👍🙏🙏
Nice explanation. please upload a video for radio occultation.
Mam how statilite work in geostationary orbit or Geosynchrnus
Mam, why we put satellites more through pslv rather than gslv
because most of our launching stuffs are not so heavy and build for polar orbit
Hello Mam
Does the magnetic poles are nothing to do with Orbits of the Satellites?
mam it help me a lot
Madam excellent explaination..pls continue the topics..
Easiest way to understand, thank you madam.
Great
Thanks alot Madam... thank you so much..
Excellent explanation mam
How long this satellite runs with fuel ? If it is not fuel how it’s been running for long time
Solar energy
Kamal ka xplanatn
Wonderful explanation
Mam awesome.. i was actually scared about this part and u made it very easy. Could u do imp 2019 CA as well?
people... its not the velocity that equals the gravitational force.Gravity is balanced by Centripetal force which is resultant of changing direction of velocity
Very nicely explained,thanks.
Thank you mam.
Pls also enlighten us by making difference between sun synchronous and leo
The Best explanation Madam
Respect Madam Tell me about Why we live in Earth and What is the Purpose of our Living? Actually I'm Frustrated bcz UPSC mains preparation
Plz tell about MEO also
7.42 , how come it will again come to the same point after 90 mins , when u said before that in polar orbit satellite takes 90 mins to travel from North to South which means it takes 90 mins to travel 180 degrees dn how come the same satellite will travel 360 degrees in 90 mins .. if I m wrong plz clear it for me may b through comment if possible
Polar orbit lo rotate avadaniki object ki energy avasarama
Thank you very much mum.,
Can you please explain in Telugu medium.
Thank you ma’am 😌
Thank you madam.. . Telugu lo explain chyyandi.. .
Thank you so much ma'am.... All my doubts got clarified 🙏
Thanks a lot mam for the lucid explanation☺🙏
Thank you so much madam
*THANK Q MAM*
Loved the explanation. Thanks ma'am 🙏
Much informative...!
Super
Geo= synchronize?
What is lowest length orbit from earth, it's hight from land
Low earth orbit 150 to 2000 km
Thank you miss
Upload more about space, DRDO, Oil exploration man..it will be helpful for us
Plz increase your speed madam
If possible plz explain in telugu.
Very nice video though...But frequent "Particular" distracts
Clarity is missing in this video...
Subtitles vaste bagunnu madam
I think u r from telgu
Indian English Gonna Kill me!
Very
Nice
Thanks ma'am 🙏
Super
