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.
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.
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 !
Thank you Rami, you explain things so easily! Greetings from Nicaragua.
I wish this series had been available when I was learning all of this the hard way! Good info Rami. Keep it coming.
Beautiful explanation, the graphics made me finally understand dilution of precision, hope you keep this topic up for a while

Thanks a lot for this video man, you just saved me my Satellite Surveying Course
Looking forward to this series!!!!
This is so informative. Thanks so much for explaining this!
Thank you Mr. Rami. Please add another videos showing how to setup GNSS receiver, data collection and data processing.
Very nice initiative! waiting for the next episodes!
Wonderfully explained! Thank you!
i’ve been waiting for this!!!!
Great! Now please do a series on how to get the most out of Emlid RS!!! :) :)
You have a gift for explaining my friend!
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.
Great stuff. Looking forward for more content !

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!

I teach this stuff myself, you have it really polished video and it's really well explained, demonstrated and analyzed.
Este video está genial, incluso con los subtítulos en español. Me ayudó mucho 😀
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.
All the way from Namibia 🇳🇦 ❤
Awesome! Thank you rami!!!
Thx for the simplification !
Thank you fro the video it really helped me understand more about trilaterlation.
Found it great,, thank you

Hello that was a great work done. Please can you work on converting the coordinates into longitude and latitude and plotting them on Google earth. Thanks
Sir, I want to buy a GPS receiver, I have two preferences as my budget is constrained, either Comnav N3 or ChcNav i83. I would appreciate it if you could suggest which one is better out of these two.
Thank you for this video! I have two questions: How can I check if I have a "reference frame" close to me? And what is the max allowed distance in order to use it?

ask your survey office in your country, most times distances vary from 5km to about 80km

Thanks for your videos. Can one purchase a receiver that can produce GPS measurements to the nearest inch? It would be extremely helpful if 2-4 GPS readings were commonly integrated into property surveys (at various extents) to better address accurate positioning of property corners in GIS applications. In areas without any clear aerial points of reference, I'd be happy if it were accurate to 1 foot. If only orthophotography (along with multiple GPS readings) were also commonly integrated into surveys.

We only use javad gnss. And surveyors measure in tenths not inchs just fyi. Our equipment is around 30,000$ gets down to the thousandths of a tenth .000
Hello Rami. I have some surveying equipment that I would like to have tested. Do you have any suggestions on how and where I can get this done ?

Please, make a video about multiple traverses in same project and how to adjust them in Civil 3D. There is no tutorial like this in entire KZread, mainly when you have like 2 or 3 days of different traverses and how to make them to interact and process them to get the whole drawing. Thnks!

Nautix X6 pro vs IPhone 13 pro Which is useful in surveying. More accurately
There is a satellite for India (INSAT). Which is a part of GNSS.
Good 👍
Today l was trying to understand the difference between two methods while l was working at office.( l am a civil engineer) Now after two hours came home and watched your video about the same topic .Such a coincidence or my brainwaves sent signals to the your satallite .

Hello good video but there is a small inacuracy in your statement. 3 satelites is not enough not because it is not accurate enough. But because to solve the position of your receiver, you need to solve 4 free parameters. Then yoo you need at least 4 satelites (4 measurements). With 3 satelites you cannot get a position. I guess you know what are the 4 parameters. X, Y, Z and ... the clock shift between the satellites and your receiver.

You are correct, the “solution” you get with the third satellite isn’t enough. I guess I should clarify that not accurate means not enough parameters solved to have a practical solution. We use three satellites for mathematical testing.
