Network RTK in Michigan and Ohio

[@manusairsoft6359]

I've been finding my geographical science course pretty difficult in college, my motivation was slipping but with these high quality, entertaining videos I've gotten that passionate interest back!! Thanks alot for that and keep up the great work!

[@MARTIN-xd6ot]

It took me 6 months of learning Pix 4d Mapper and using an Enlid RS3 Rover to create a point cloud for 3D measuring. This video cleared up a lot of Enlid information I was not understanding. Thank you for putting out your educational and entertaining videos. You are a Teachers teacher. WISCONSIN

[@scotth1469]

I do aerial mapping with UAVs and have been recommending your videos left and right to my clients who ask me about how ground control setting and GPS surveying works. Your content is great, keep it up!

[@shafibajauri4988]

My man traveled to another state to make this video as credible as it could get . Bravo and thanks man !

[@Anthonyg909]

Hi Rami, found your channel and I'm hooked. Can you do a video on State Plane Coordinate Systems and Grid vs Ground survey?

[@grigoryaneric]

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.

[@arnaudlrc]

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]

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.

[@MeasuringMasters]

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 !!

[@DroneMappingTools]

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.

[@itsjared]

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.

[@Drone360pilot]

Great video, Rami . Appreciated ! Pls keep publishing more content about GNSS PPK & RTK . Thank you!

[@gabrielsastre2873]

Great video. In Argentina NTRIP is working very good. I have used it few times and it saved me a lo of field work time. What i normaly do is measure a point with ntrip, and then use that one as a base point for my recivers, so my work is already georeferenced. Greetings from the south..

[@wenjieji9699]

Thank you a lot!!

[@landivarscott]

Thank you for your video. I found your explanation of CORS very easy to understand. I will share this video for anyone requiring training on how to setup the equipment. 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.

[@gorandiaye50]

Thank you dear Rami for your great video!

[@maxhudsonchaves]

funny and very interesting. great content

[@josemanuelvalladares1831]

Great channel!

[@tszabon]

this is very interesting channel. Subscribed.

[@freedomhillbilly348]

Didn't expect that. If you want to get out and do some REAL surveying outside of a flat campus or manicured backyard, you have a standing invitation to join me in the backwoods of NH and really put that kit to the test! Don't worry, I usually carry a compass so it's unlikely we'd get lost. lol.

[@RamiTamimi]

That sounds like an adventure!

[@lztoniolo]

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!

[@deanhanchett379]

Very helpful!

[@tadamb1]

We find that using our Trimble and Topcon gear with NTRIP they are drastically more susceptible to losing fix around obstructions and overall drastically less accurate. Still awfully handy for many applications though... Just not for final staking in a "fine grade" situation!

[@Chief.Surveyor.AliQassim]

Great video mate

[@M--oy1pe]

your pole is in meters America: *cries inside*

[@ammarelgazzar8782]

Great job 👌

[@prukutkin]

Here in Mexico we have Cores from INEGI, but you can just download de RINEX, doesn't have NTRIP. I hope you make a video showing how to posproces a static point using RINEX from a core and from the Emlid Rover.

[@kadry93]

Puedes levantar un punto estatico en tu casa, postprocesarlo contra inegi y despues usar emlid caster (que es gratis) para usar la base por ntrip con el rover. emlid caster es gratis

[@prukutkin]

@EL NUEVO MUNDO - RADIO PODCAST lo que quiero saber es cómo procesarlo. Lo intente con TBC y no pude, algún paso me salió mal y no he encontrado mucha información. Además de que sólo tengo 1 Emlid.

[@BERNARDIN_1986]

Awesome video, thanks for sharing ;)

[@BERNARDIN_1986]

is it possible to do the same with emlid rs+ ?

[@zeraimebrahtuhabtu226]

Brilliant and eloquent explanation Thanks buddy. One extra question outside GPS/GNSS, that's Leica ' sets of Angel' if possible . Thanks

[@jasperlawrence5361]

thx

[@fawazalfaydi3048]

Hi Rami, thank you for the beneficial information you gave us, would you explain how to do the same method in middle east (Saudi Arabia) please?

[@marcusgilmore4311]

Ntrip in Texas is $500 a month or $1500 a year

[@stalingrado1953]

In Ecuador is free.

[@deanhanchett379]

Could you do a video showing how to find coordinates of section corners that are on imbedded in roads in Michigan?

[@johnwalker2542]

Rami why are those gnss receivers so cheap compared to a name brand receivers ? Also how much were the import taxes on your receivers? Also, would you recommend these receivers for some one who is just starting out? Your videos are awesome! Keep them coming !

[@RichMilennials]

awesome!!!

[@moisemayali]

Interesting

[@Chief.Surveyor.AliQassim]

Thank you very much Is it possible to get a video explaining the processing file observation static ?

[@zinedine9939]

The NTRIP protocol (Networked Transport of RTCM via Internet Protocol)

[@SantiagoVelezRestrepo]

Love ya bro!

[@biencruz9993]

We call it Active Geodetic Network System (AGNS).....

[@bobdoby9178]

Very informative! I watched the P4P vs P4RTK with GCP's. This one introduced the COORS network. Will you consider doing a video using an RTK drone, a Base/Rover unit utilizing COORS and setting out GCP's? 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.

[@mwaledex]

Is it possible to setup your own cors network in an area that already has an existing network?? Let’s say the one that’s currently existing only covers a small area and you want to setup one that will cover the entire state.

[@SebastianZehner]

Your videos are very helpful. Thank you for this. I am still learning to improve the accuracy. Do you know how to use the CORS network in Paraguay?

[@tszabon]

@Rami Tamimi Could you explain how passive GNSS data works?

[@arcangel85]

Great videos! can you show how to take ground control points using emlid rs2 for photogrametry? greetings from Peru!

[@dewmelo]

Can you review the walker rtk and compare it with the rs2?

[@zwiftfrance]

I don't catch the difference between base location and mountpoint.

[@tomthomsen11]

One thing I've not seen/heard you discuss is grid vs. ground distances. It looks like you do everything in grid. Your thoughts on this?

[@pedroflores3417]

Hi Mr Rami how are you? I have a question what type of program do you have on your iPhone and can I use the iPhone 12?

[@AerialImagingResourcesLLC]

I also live in Michigan and am looking at the exact same document you are and entering in all the info correctly and have a stable internet connection to my controller and my rover (DJI) drone with RTK, but no matter what port or mount point I try, it always fails to connect. Its driving me nuts. Do you have any idea what I'm doing wrong?

[@dnash57]

Rami- Any experience with the Reach RX unit?

[@volantdrone]

What do you mean by taking 10 shots and averaging them? Are you shootijg ground control or are you taking 10 shots at each location and averaging the results?

[@RamiTamimi]

The GNSS receiver is measuring the same location 10 times, and averaging the 10 observations into one.

[@spazoq]

Is there a distance issue using CORS over cellphone? Everything I've read said 6 Km or less. How does distance effect a correction signal sent over the internet?

[@extremely_average8296]

How accurate is this compared to a typical base station and rover setup?

[@M0JHN]

Rami he do you get a 3rd dime Timon in another plane on a surface ie you have x and y but how do you point a z value for example the corner of a door for referencing guns into point cloud scan data

[@LhounJaaf]

Thank you, Rami, for these educational videos. My question is, do you have a page on Facebook where you publish information about geodesy?

[@RamiTamimi]

I really should start one. I just have a community page for all my followers to interact with.

[@luistoledo1402]

in texas?🤝🙏

[@raymondokyere4040]

Is it possible to connect two rovers to the cor station and at the same time both to the reachriew3 to collect points?

[@TheJoncic]

Do you need a sim card for cors network? If so, does the Emlid come with one or do you have to get one with a specific wireless provider?

[@deanmartin6222]

Is this also applicable for D-RTK 2 GNSS Mobile Station?

[@EdgardsGranados]

Is there no problem to travel with the receiver as a hand luggage? I think in battery risk or even pass thru x rays and officers asking questions about what that device is?

[@iloveamerica1966]

Why can't the iPhone correct its own GNSS using CORS?? IPhone is a dual frequency GNSS receiver- albeit not high grade, and it's an internet device that can get CORS directly. Why can't it do RTK on its own GNSS; does it just need someone to write the app??

[@0eyesopen065]

Rami what an amazingly helpful video! Quick question: how do you manage to connect your iphone to the Rs2 without using the wifi connection? My iphone x will not connect via bluetooth. In the emlid user forum, it seems that iOS does not support bluetooth connection to the Emlid, but in your video, it looks like your iphone is still connected to the verizon network for internet. Do you have the time to explain this to me?

[@RamiTamimi]

So in RS2 I added my hotspot information. So everytime I use the units, I turn on the hotspot on my phone and connect to the devices and to NTRIP

[@chrismoore9672]

Is it possible to do this with the NGS CORS network as well?

[@benjaminlim328]

do you need a SIM card in the Rover for NTRIP?

[@elrey5523]

Rami I have topcon base and rover and fc5000 controller how can i use mdot or what other companies can i use here in california. So i can just use my rover and not my base station ?

[@EdgardsGranados]

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?

[@trollenz]

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.

[@many_worlds]

If there is no CORS we can use PPP

[@zwiftfrance]

My understanding is that you do the same process in 2 different locations. True ?

[@razvanafloarei6256]

Is CORS the same as GNSS?

[@sie4431]

Is there any way to set up a standard GPS or smart phone to do corrections for higher accuracy?

[@jwangosho]

The basic requirement for RTK is that the GNSS receiver must be able to make phase measurements.

[@tszabon]

@@jwangosho Could you explain?

[@jwangosho]

@@tszabon These things are able to resolve their positions to a cm by making use of the GNSS carrier wave whereas the ordinary receivers just use the code. The "corrections" transmitted via NTRIP and received by his rover are simply code and carrier wave measurements made by the base or computed by a software in case of VRS, FKP, etc.

[@iloveamerica1966]

Anyone tried to connect iPhone 13/14 to CORS? There must be an app for that, no? Then a cellphone/ iPhone becomes its own RTK base station.
