Setting up a Base Station Over a Known Point
Вставка
- Опубліковано 3 гру 2024
- When conducting RTK field surveys, we usually establish a base station with an Emlid RS2 GNSS receiver setup over a known point. In this video we explain how we:
1) Locate a Permanent Survey Mark (PSM)
2) Setup our base station (Emlid's RS2 GNSS receiver) above the PSM
3) Configure the RS2 with the coordinates of the PSM and set the base station to transmit corrections via LoRA radio.
By correcting the data received by our rover GNSS receiver in real time using a technique called Real Time Kinematics (RTK) we can obtain survey grade accuracy for our rover.
Keep in mind that your RTK rover may be a second GNSS on a survey pole, a drone capturing photogrammetry data or even a hydrographic survey vessel!
The benefits of establishing our own base is that we can work in many locations independent of NTRIP or other services which can provide corrections.
Fantastic presentation mate love it
I’m not a surveyor, I operate excavators etc and love my gps .
Keep the videos coming mate 👍
Hi Michael - thanks for that feedback. Not sure which model you're using but you may be interested in our latest video by our partner company Map Gear - here's a link : ua-cam.com/video/o8BUzffeIxY/v-deo.html
A great way to showcase workflows in the field and promote the industry. Keep up the great work.
Always helps to have the right tools 🙂!
Excellent explanation! ! Thanks for sharing knowledge!
Thanks Gilberto - we have plenty more to share! Stay tuned 🙂
Thank you so very much, I get out in the field so rarely that I forget small steps each time. I never knew the tip about adjusting level 2 points at a time, handy. Handy that youre even using the same GNSS stuff i am, didnt know that you could take GPS to 1 HZ without having to play with the bandwidth.
Excellent and helpful video all around - thanks so much!!
Really good information, thank you for a clear video on this.
This is a great video Alistair, well done.
It's only the first one of yours that I have seen, but I have subscribed as I suspect you will have many more that I will enjoy and learn from.
Looking forward to following along
Regards Ben
Hey thanks Ben, looks like you've been creating some great material too! You've been at it a bit longer than us - it must be great to be able to look back at the huge amount of material and see what has changed and what has stayed the same. Definitely subscribing to your channel :-)
@@MangoesmappingAU hahah, thanks mate.
Yeah its a bit of yes and no. It is good looking back but at the same time, there are some videos that I have done that I find annoying and cringeworthy and so want to go and edit them, but I can't hahahahhaha
I have actually been pretty slack lately, I don't post as often as I use to.
I find the video part easy, it's the editing and the copy and the heading and the captions and the thumbnail and all that sort of stuff that I find time consuming and boring.
Last few years I have sort of moved over to Instagram and I find that a lot easier, as it is just point and shoot and that is it, it is up and I can move on.
But unfortunately, its too had to search for stuff on there, so I think UA-cam will always be the place people go when looking for something in particular.
So I guess this is a bit of a kick up the butt for me to get a move on and start posting again hahahahahahah
@@GeelongCableLocations Yes - completely agree - it does take heaps of time but you can't beat the search factor of AI Google :-) ...
"The Mangoesmapping online videos show me new and amazing things which I would really love to use. Things like the Benchmrk app and using a smartphone as a controller. It's a really great source of new information and could allow me to work with more speed and convenience. I love these amazing videos.".

Thank you for your feedback Shahayaz Khan. We have a long list of material we are keen to film and share. Stay tuned!
Can you guys shoot and post a video on how to create a new Known Point? I think you can do this using a procedure called Static Processing. Thanks!
Hi Eric - we do a heap of projects to create known points using static logging so we will definitely make a video to share the finer points of this process.
I'll shuffle it up the priority level on the 'to do' list!
@@MangoesmappingAU awesome, thanks, I really appreciate it!
@eturn23 We just published a webinar yesterday that detailed this process. I hope you find it useful!

Hi. Thanks for the video. What is the app you used for benchmarks? Thanks.
Hi thanks for that feedback - sorry about the delay! We use Benchmrk by Geolocata. Here's a link: play.google.com/store/apps/details?id=com.storytellermaps.benchmrk&hl=en_AU&gl=US. or for IOS: apps.apple.com/au/app/benchmrk/id943242395
@@MangoesmappingAUanything for USA?
@@timd9430 Not that we are aware of. I imagine it might be a bit more complicated getting unified data into a single point for the USA.
Thank you Sir for all your useful information. We have been using the Emlid RS2 for several months and very happy with it.
What do you consider is an acceptable margin of error when staking a point to verify accuracy
Maybe it depends what brought are staking, drainage on sloppy sight needs less accuracy compared to bolts for precast steel
Hi Eddie, how is Emlid RS2 comparing with Leica/Trimble? Thanks!
Not taking curvature into consideration? 🤔

Hi Wheeler. Could you elaborate on that?
Don't need to on such a small project, generally only used on long terrestrial traverses or large survey projects. The software he's using is based on a projection and will allow grid surface to ground surface corrections.

Alistair was making the tripod legs shorter to help the cameraman (James) with filming 🙂
