Beta firmware v06 0829 support for HAS on LG290P

Hi @sparky
Thanks for the clarification on this.
Did they mention any probable date for v07?
A Quectel post in Germany mentioned the last quarter of 2025.
We’re already there. jaja
Best regards

Hi everyone.
Has anyone seen different precision results depending on the parameters in the PPP command?
$PQTMCFGPPP,W,2,2,90,0.01,0.01
The 0.01s in the example represent horizontal and vertical precision, but it seems to me that the results are the same regardless of the changes.
Can anyone confirm my observations?

Regards, Angel

Yes there are the same also in 5.00 meters,
if U can see at the age count,it go beside 12 aka 120 and not 90 the minimum…

Hello.

The document shared above regarding the deployment status of Galileo HAS states that Phase 1 is not yet fully operational, and the service currently only provides code bias corrections, as well as orbit and clock corrections. Phase corrections will have to wait. And if I understand correctly, it is these corrections that will allow for an accuracy of <20cm horizontally and <40cm vertically. Personally, in France, using in rover mode, I obtain a horizontal accuracy of 50cm and a vertical accuracy of 100cm with an antenna on my rooftop. I live in urban areas, buildings of 3 to 5 stories can interfere with the line of sight to satellites to the north and south. I have configured my receiver for GPS and Galileo only. I will conduct further tests soon, adding GLONASS, then BeiDou, and then both, to see if uncorrected constellations interfere with the observation. I’d also like to test the integration of the HAS function in Survey-in base mode to see what the results are, but for now I’m struggling a bit with the configuration. I’ll be sure to share my results here, and if it works, I’ll post my configuration on the Quectel forum since I’m a Mozihao user.

We’re seeing improvement from 1’st Quarter to 2’nd Quarter this year :slight_smile:



But unfortunately, users in the USA will never receive the benefit atmospheric corrections or phase bias corrections, since Service Level 2 will be for Europe only :broken_heart:

@2M2C, Hopefully you will be able to report wonderful accuracy in France when Service Level 2 hits :wink:

Are you sure the United States won’t be able to benefit from phase correction? The ESA’s datasheet seems to indicate that phase correction is included in the SL1 service level and that, as you say, atmospheric corrections are reserved for SL2. It also seems that we still have a few years before we see SL2 deployed :confused:

Have you been able to run any tests yourself with the LG290P? I’d like to compare my results with other users around the world. Comparing them with the UM980 results could also be interesting :slight_smile:

rftop, don’t worry, I found your posts where you share your tests with the UM980. I’ll read them with great interest. Thank you for sharing all your observations :+1:

No, not now :slight_smile:
I should amend my previous statement. It appears the US/Global will get the benefit of Phase bias corrections once SL2 is reached for Europe. Thanks for questioning that :+1:

SL1 does include Code (pseudorange) measurements, however, Carrier-phase measurements will be SL2. The documentation uses a trick with the “fine print”. Link

Hi everyone.

November is already underway and the Galileo HAS fixes in a final firmware update from Quectel still haven’t appeared. Does anyone have any new information?
Cheers

Hi everyone.
We contacted Quectel and they informed us that they have a new firmware version:
LG290P03AANR01A06S_PPP_TEMP1107.zip
But they refused to provide it.
Does anyone know anything about this firmware?

Regards, Angel

This issue seemed to be getting resolved with the first beta firmware releases.

But now it’s slowing down again. More questions and more waiting.

The idea behind a beta firmware is precisely that: to test it and provide feedback. But…

Jasper Wan from Quectel sent (thanks to Angel @amlago) beta_fw…
Gst seem work now:

$GAGST,091202.100,1.981,0.785,0.143,42.020,0.536,0.591,2.609*46
$GAGST,091306.000,1.663,0.559,0.135,42.444,0.390,0.422,1.862*46
$GNGST,093312.800,1.468,0.128,0.048,1.521,0.048,0.128,0.144*76
$GNGST,093857.900,1.626,0.973,0.963,108.535,0.972,0.964,0.995*7A

note: -in galileo only setup H is different 4m from gps…
-HAS began in differential (2) mode and got float (5) when ready?
-diff.age reach even 2 to 12 despite different setup in $PQTMCFGPPP

Hi Marco (@bamarcant)
The firmware arrived in my country in the early hours of the morning, and it was raining the next morning.

So I’ll have to wait to be able to test it.
Your tests look promising.
Let’s keep in touch.
Regards, Angel

Initial tests with the Postcard inside a nylon bag due to the rain.

Oops, that’s all I had.
I have the Postcard connected to the CHC Landstar 8 software.
As Marco says, it started in dgps (2) and took quite a while to switch to float (5), and that’s when the accuracy dropped below 0.20 m.
That’s what it seemed like to me.
Currently, the indicated horizontal accuracy is below 0.10 m.
I’m collecting data points to do some statistical analysis.
I’ll share the results later.
Now it looks more promising.

Regards

Hi Marcos (@bamarcant)
I think this firmware works much better than the previous ones.
I’ve obtained positions with deviations from the fixed point with coordinates known by PPP Canada of less than 0.10 m in most measurements.
Your image seems to be one of the best we’ve seen.

Here’s an image of the Landstar 8.

The small circle has a radius of 5 cm and the larger one a radius of 10 cm.

The circles are centered on the coordinates of the point by PPP Canada.

I also managed to stake out the point in real time with deviations of less than 10 cm.
I took the postcard and walked around for about 30 meters, then asked the Landstar 8 to stake out the point using coordinates known to PPP Canada.
I located it very precisely, within a radius of 10 cm or less, almost like with RTK.
I don’t want to say we have everything solved yet, and I’d like to determine the best configuration: frequency (either 1 Hz or 10 Hz), GPS and Galileo alone or with all constellations, etc.

But we’ve made a lot of progress.

Wow Marco, that looks good !
Since it’s a GN message, I assume you are using both GPS + Galileo for that test ?

Your report sounds great too Angel !
