Visible Float & Fix solution status, elevation & antenna height, collection time & Moving the Base

Normally only up to a kilometre or two but if I get a series of poles to collect data for it can go out to several MK’s, in urban areas the distances are much shorter but the line of sight and obstacles & buildings is much worse and could cause loss of radio signal.

I’m hoping to get RTK to save time & effort and I haven’t ventured into the area of PPK yet.
I’m also toying with NTRIP using AUSCORS at to moment, so that’s another learning curve I’m on right now too.

At what point or how long should I wait between selecting Collect and selecting Accept when collecting survey points?

Thanks heaps for all the support so far Tatiana.

Hi @Bruce_Power_Comm_Ass,

In the line of sight, LoRa achieves the range up to 8 km, so 1-2 km might work for your conditions.

I’d not recommend changing the base location, as it might not allow you to gain the accuracy you need.

What’s the distance to the this NTRIP station?

5 seconds should be more than enough.

Hi again @tatiana.andreeva,

I’d like to be able to get to a site and if I have internet service grab just the rover turn on and log in to NTRIP and start collecting points OR if no internet is not available setup my base and setup LoRa and start collecting points :slightly_smiling_face:

Just another question; I want to change the survey data output from LLH to ENU but don’t seem to be able to and my exported CSV data is still LLH even though I change it in the Position output tab, what am I doing wrong please?

We only have around 40 AUSCORS NTRIP Broadcaster points across Queensland, so I’ll rarely be within the ICSM recommended 20 km; what is the error margin as I get outside the 20 kms from a Broadcaster points?

@Bruce_Power_Comm_Ass,

Take a look at the Working with NTRIP guide, it might be helpful.

At the moment, only the LLH format is available for Survey projects.

For RTK, we usually recommend not exceeding the 10-km baseline. Accuracy is decreased approximately by 1mm each km of baseline.

Thanks heaps for your help @tatiana.andreeva

It is so disappointing and to find out now that what is in the Emlid Docs and the ReachView App is misleading, because having the ENU position output format was a major point for me in purchasing the Reach RS+ because the ENU output format would allow me to upload the data straight into the modelling tool without having to do LLH to ENU conversions on everything :rage:

Emlid obviously intend to include this functionality because its in their documentation and App so does anyone know if and or when Emlid intend getting this function operational?

Can you point to the phrase where it is misleading, so it can be corrected?

Hi @ Christian Grüner

Surly it would be better if EMLID got the function operational rather than remove the options from the documentation and application!

In the meantime, you could use the “Position output” to send the live position data to your mobile device where a third party survey app can do what you want and work in ENU.

The page you link to is not the survey output, but the position output :slight_smile:

Hi @bide

Can you suggest a comparable, easy to setup & use 3rd party survey app to send the live position data to.

Cheers @ Christian Grüner
That’s the setting I was told I could change if I wanted ENU instead of LLH format for my survey export data. Its a shame the only support for such a popular product is via its user community forum and not by the company’s own customer support area. Anyway, glad I didn’t pre-order the RS2 now.

Here on the forum, by a reseller, or by Emlid support?

But they do have that? :slight_smile: they helped me when I bought my RS+’s last summer.

I thought it was on this forum but I cant find it now, so it must have been elsewhere, Ill troll back through my emails. :frowning:

The Emlid support outside the forums is sparse.

Anyway; enough wasting everyone time, it cant do what I need so that’s it!

The tool does exactly what you need. The current reachview app does not. Send position output to mobile topographer pro or QField. That reachview does as @bide already said. Or just use reachview as is and import survey into QGIS and apply whatever transformation you desire. Again the tool works for your needs just not the app.

Here is way in QGIS:

Hi @Bruce_Power_Comm_Ass,

As @bide said, ENU format is available for position output in the ReachView, not for the Survey tool. It means you can transfer the ENU data to any third-party software. You also can record the log with ENU positions in the ReachView.

We usually answer to all of our users here and on support@emlid.com within 24 hours. We always strive to resolve all the issues as soon as possible.

We recommend creating threads on the forum as there are a lot of users that experienced the same issues earlier and might participate in the discussion. It allows getting an answer faster. It also helps other users to find a solution to their issues because most questions were already discussed here.

Thanks for everything @tatiana.andreeva

Can anyone tell me in terms of sky visibility the affects of setting up my RS+ base on a pole-mounted bracket on a power pole for corrections over LoRa (is there a preferred quadrant of the sky in Australia that visibility should always be maintained) and is there a substantial interference and error risk of surveying the centre line under power lines with my rover RS+ in LoRa and or NTRIP modes.

You are giving your units a chance now? :sunglasses: This would be your best location for a clear skyview assuming no nearby foliage. However, you may get some electrical interference on the equipment but I have nothing scientific to show it has an affect on precision. What size lines we talking here? Use fiberglass survey rods…

I had base very near the lines and LoRa held for almost 2km. What is your anticipated baseline? NTRIP may be better option over wifi. See a thread I started below:

Hi & thanks for you response @RTK_Hunter

Instead of using a tripod out in the open my intention is to mount a temporary bracket on one of the power poles in the survey (2m to 3m up for security from stock and the public) so being only 200mm to 400mm of the pole I thought to pole may block a portion of skyview, hence my question about what would be the best side of the pole to mount it in Australia to reduce this.
Powerlines range from low voltage (240V) to sub-transmission 66kv in urban, ruran and remote locations.

2km will cover 80% of what i do. I will use NTRIP where possible but the we only haveing around 40 AUSCORS NTRIP Broadcaster points across Queensland accuracy will be diminished in a lot of cases not to mention internet access is limited.
