[@naturesounds1895]

Hi Rami, I’m wondering if you can help this enthusiast understand how you find the exact coordinates for a point for the base station or a total station when needed. It seems to me many total station operations you need exact coordinates of a point and for the base station you also need exact coordinates. It seems to me it’s a bit like the chicken and the egg situation. How do you find that exact coordinates of that first point? I’m from the U.K. not the US if that changes anything. Thank you.

[@Richard_GIS]

Most governments have an open data portal or map where you can normally activate and deactivate layers, there should be all points (at least that one from the governments). Have a look for example in www data gov uk (urls do not work in yt), sometimes it also helps to go for a city data portal - or just ask a local surveyor

[@FrozenTint]

These were existing coordinates that you can find from different surveying agencies or the government.

[@marcusgilmore4311]

Can you go over logging when you don’t have a known gps point and correcting base location through opus?

[@fabianstevenne]

Hello, thanks to share all your knowledge! if there is no known point near the place we have to survey, how create a georeferenced landmark with the reach?

[@samrajdwivedi]

Depending on your location, you might find a geo-referenced point from hydrology department of your area, land survey companies near your location or a GTS benchmark. You can then use the baseline transfer to geo-reference your nearby point from the already existing geo-referenced point ( legs of transfer depend on the distance between both the points)

[@raffriff42]

Try searching for " CORS" (Continuously Operating Reference Stations, run by local government agencies)

[@jehnclavel7310]

what up should i use when finding the location coordinates.

[@kirkhusker6749]

Rami, It’s my understanding that if you enter northing and easting values for your base station and want to layout points in NEZ that the emlid software will make these conversions automatically. Is this your understanding?

[@ahmedhaneen5120]

Dear if we dont have the coordinate of control point , whats can we do .

[@sadathbadru9031]

You know the mining of control point

[@gruen89]

Is it possible to messure without without seeing the base? For example in the back of a building And second question Is the rover and base able to messure in a case rover has no connection to satalite? Maybe to get the hight of first floor in a building?

[@rahel602]

Kindly ,, I need how I can use the localization option in GPS Sokkia GRX3 ??

[@fabianstevenne]

Hi Rami, is the radio connection between the base and the rover can through a dense vegetation or a building. I’ve noticed that he rover lost the fix green each time there is something in between the two recievers.

[@droneoccitanie]

Do you have a video explaining WGSxxxx ? Thanks.

[@tedbain6904]

Hi, can the emlid reach R2 or R3 base and rover Proform cogo functions.

[@MatthewIvers]

Thanks Rami! Super informative. Do you have to have a known survey monument or control point with coordinates to set up the base station to achieve high level of precision? Or can the base station be placed anywhere as long as it is fixed to achieve the same level of accuracy?

[@Fringedweller1000]

Can use multiple bases with one rover, as the rover may be obscured by obstruction to the line of sight between rover and base but possibly visible to another base? In addition, if the rover loses connection with the base what happens to the accuracy of the rover? does it just revert to the satellites GPS position

[@seantorcello3325]

Great video! However, will the base lose its mobile connection when you're out in the field collecting coordinates with the rover? Basically will the hotspot range be a limitation, unless you have two smartphones to leave with the base and one to collect data on the rover?

[@islandsurveyor]

Good day. With these receivers, the base will not be transmitting corrections via wifi. The corrections will be transmitted via built-in uhf radio (Lo-Ra) or the internet. If the latter is used then both the base & rover will need 2 separate connections to the internet. So the short answer is no - the hotspot range will not be a limitation

[@davidkubitz5098]

I’m struggling to understand just one thing… How could you know the coordenate of this point that you setup your base station if you “rent or buy” the RTK just for that reason? In my case i picked up some points using a total station, so the only reason im renting an RTK GPS is to reference a materialized point that i used as a base point for the total station. I know that in someplaces you have a geodesic mark, a fisical mark, that has already known coordinates. But in a case that you don’t have this, can you just set up your base station anywhere you want and start yours measurements? I hope you understand my question, English is not my home language 😂 thanks for now

[@garyjoaquin]

1. What is the maximum distance permitted between the rover and the base station? 2. Is a direct line of sight required between the base station and rover? Will this technology work in a forest where trees may obstruct signals? 3. You referenced a known monument base station longitude and latitude coordinate. If you are in a wilderness setting how is this point obtained? If you are in an urban setting, how is this point obtained?

[@khalifaalyatama4658]

Can i measure elevation of the building from sea level ?

@Hey Rami. I notice your using the Emlid GNSS receivers. I wanted to know what do you think of them compared to older brands like Topcon, Trimble and Leica. Is the Emlid better or why would the other brands be better or not?

[@volantdrone]

Did you create that point using OPUS or did you use traditional survey methods?

[@mesfindelelegn1165]

Is RTK GPS/GNSS requires additional post-processing?

[@RamiTamimi]

No it does not! RTK stands for Real Time Kinematic, meaning you get the solution in Real Time.

[@westcoastaerialimagery4690]

You will if you want to use actual useful coordinates not wgs84, should have used a local project grid for pickup

[@aminabdo9760]

[@Ragtime456]

Hi Rami, I have two RS-2 (base and rover). My question is which is optimal connection between the base and rover. With my Base connection via MiFi (stationary) would you suggest the rover to use a sim card, LoRan or ??. I'm new to all of this and have sunk a few $$ in the equipment and want to get the best out of my investment.

[@SzaLeo559]

Great information Rami, thank you for posting. I've been using the Emlid Rs2 for a while now over Lora radio. Do you have any videos on how to diagnose when your Base and Rover recievers lose fixed connection intermittently? For example, how do you know when it can be a simple fix like changing the frequencies or something where the only way to achive fix is to switch from Lora to NTRIP?

[@FourthWayRanch]

what's the best gps to get for a rover now?

[@mahanmahani5907]

Nice video it really help me. I’m just wondering if we have a base and a rover set up, is it still necessary to have a p4pro with the rtk module or not ?

[@techwithchenchoep5818]

I have some concerns regarding the measurement of base station antenna height. You were measuring without installing the receiver on the tribrach. Doesn't the antenna reference point make sense? Shouldn't we measure the antenna height from phase of antenna?

[@oneputapigfarm]

Hi Rami, thanks for the video. I am curious, when you set up at a completely unknown place with no reference points, how do you calibrate your instrument?

[@islandsurveyor]

The point will have to be calibrated from a known point either by observing a known point nearby or connecting to a network of receiver(s) such as VRS or NTRIP.

Which is better on setting rtk survey? Just find a known trusted known point as base as u did then do rtk Or Make a control point lets say at the middle of two known point and then do a site calibrate to get the and compute the coordinates of the control u made for base? Bec. That what we did before Our boss doesnt want to put our based on already made primary control point, he want us to make a control at the middle of two primary control and do site calibrate on both primary control to get the coordinates for the base point weve made. Then after that we do the rtk.. Bec. The reason of that i heard our boss said What if theres error, how can we apply a correction im not sure but i heard something like that idk.
