What is GPS/GNSS

In this video we will cover the concept of GNSS and how receivers on earth are a part of a three segment network that allow for a high accuracy position utilizing satellites in space.

I don't know a thing about surveying, but I think that it is fascinating what surveyors do! I look forward to learning from your channel, Rami.

[sudipshrestha]

thats really a helpful video sir for understanding at a basic level

[ivan]

My profession has absolutely nothing to do with this, but I find your video's really fascinating.

" _Imagine_ the earth is a sphere."

Rami confirms his position on a flat vs spherical earth 😂

The GNSS explanation was very good. Take a good look at the full video. Take care. See you often. ^^

I wish this series had been available when I was learning all of this the hard way! Good info Rami. Keep it coming.

Hello Tamimi. Excellent content. I'm so close to be a surveyor in Peru. And you channel is perfect, because I learn about my field and also I get closer to be a bilingual. Please, continue with the awesome content.

[sebastiankrzos]

Set this up for my first time at my new job. Thank you!

I'm an Excavation & Utility contractor and have no formal survey training. While I do have a head for math, Rami makes this appear to be so simple to understand. While I have been using a Total station to do layout, I'm jumping in with GNSS !

[rodrigosuarezcastano]

Beautiful explanation, the graphics made me finally understand dilution of precision, hope you keep this topic up for a while

[tehpiratezorz]

GNSS lesson over lofi beats = 👁️👄👁️

Edit: Seriously though, this is an excellent distillation of what I found to be a rabbit hole of information when I was first learning this stuff. Subbed.

[lyndonarden-wong]

Great! Now please do a series on how to get the most out of Emlid RS!!! :) :)

[gunningopher]

Pretty good video. I'm impressed that you actually called the measurement method correctly. Most people get that wrong. You were pretty much on the mark except for the control segment. You sort of hit on it when you talked about the ephemeris, but the reference station is not part of the control segment, it is part of the user segment. The control segment are the distributed tracking stations, central command location (and backup location) and all the similar parts of the system that control the satellites and messages from the ground. It computes and uploads the ephemerides, for instance, to the satellites. Newer (Block IIF maybe?) satellites can measure their own position, now, by the way.

Thank you Rami, you explain things so easily! Greetings from Nicaragua.

[torecrash]

Great stuff. Looking forward for more content !

[jaymoex]

I might havecommented on two posts in 15 yrs on youtube so take this as an honor lol. I work in GNSS Machine Control and Site survey and I love your videos. Make your next video on RTK technology and I will use it in my classrooms like I would share this one!

[carlwynmanguhekautengemoan]

Thank you Mr. Tamimi. Regards from Solomon Islands 🇸🇧

[MrJafar]

ما شاء الله لا قوة إلا بالله
معلومات قيمة و مبسطة و ممتعة
جزيتم ألف ألف خير

[waaos]

Finally, an internet explanation which is useful/ THANKS

[getinetteshome]

Thank you Mr. Rami. Please add another videos showing how to setup GNSS receiver, data collection and data processing.
