A great video would be comparing the CORS network vs having a personal base station and the difference with pros and cons. That would be an interesting video to watch.
@arnaudlrc2 жыл бұрын
I was asking myself the exact same thing. I suppose that a surveyor obtains the precise location of his base thanks to an Cors network, right? So that means that if you have an error of 2-3cm with the base station's location, every point recorded by the rover will have the same error, plus another error induced by the rover itself. So i guess that if a surveyor wants ABSOLUTE precision, he is better of using a cors network directly on the rover rather than his own basestation connected to a cors. But if a surveyor wants RELATIVE precision, he will be more precise with a basestation + a rover. Can someone confirm?
@landivarscott Жыл бұрын
The closer you are to your "base station", the more accurate your position will be. Using CORS is very accurate, but if you have a local base station on an accurately measured known point that should be even more accurate than using CORS.

Hello Rami, very nice your video, here in Brazil we have a total of 133 stations to connect, it's a small amount due to the size of the country, but we are evolving. Greetings from Brazil !!

Another great video Rami. In Mississippi you can get free access to 1 station and that station can not change. Tennessee only offers paid access and it is expensive. I think Florida has one of the best free networks in the USA. So for many states in the USA it is more cost effective to buy two Emlid Reach RS/ RS2 devices and use your own Base/Rover NTRIP setup for RTK like your previous video. With the RS (L1 only) they would simply need to use a Jetpack to provide Internet access to the Device. I have found that Tmobile has the best low data rates you can find which is what I use in my RS2 units.. With 2 units folks just need to plan ahead and do PPK processing on the Base unit if they want true RTK with a Base that is broadcasting with absolute accuracy. Keep the awesome videos coming! You have an awesome channel.

Sadly, here in Texas RTKNet is locked down to either Trimble users or contractors for TXDOT. It has a hefty subscription fee as well. So like you said Tim, we operate two Emlid Units. I found these Unreal Mobile prepaid cards ($15) at Target work ok for 3g connectivity.

I think it will also be useful to share your GNSS settings for EMLID. At the same time, how long do you average your measurement (less than 5 minutes) to obtain precise location and the coordinate system that you use. Many people find this difficult to understand and make mistakes including myself when I started working using EMLID.

PLEASE, make a video telling about how to work with GNSS receiver and Total Station at local system. I mean, how do you place a point using RTK GNSS and then use the same point for total station to stakeout a building for example. How do you apply the "K" scale factor to points, so you can work with GNSS and Total Station for the same project? When working with GNSS and UTM coordinates, there are always a difference in distance and coordinates compared to total station. How to overcome this? Sorry for this basic question, but you are the right guy to make a video about this topic. Thanks!

I'm interested in seeing the unit going from a COORS Rover, setting up the GCP's to a COORS base and then the drone becoming the rover. Thanks.

Considering the distance between rover and vrs base (+9000 km acoording to the screen) I hoped less accuracy in fixed data. We learn that we have 1 mm for each km between base and rover... Or that doesn't work in vrs NTRIP mode?

That must be an error, the VRS is a virtual station calculated around your position from a network of real bases. From 150-300km away it would be hard to get a fix.
