Unhealty GPS

Here GPS
1

Hello,
Seen this on several topic already but never seem to see an actual solution.

I have Cube Orange + (version 4.5.7)
Here4 GPS - also update to the latest (HW version 4.19 / SW version 1.14.5AC6523C ).

I seem to have all configured right, I get 32 sats and 0.5 hdop with 3dfix.
I keen on getting either gps1 unhealthy (arming denied) or “unhealthy gps”.

Steps taken to eliminate the issue:

Reinstalled Arducopter
Recalibrated compass /accl /etc…
Replaced Cobe Orange.

Any support will be appreciated.

Thanks.

@philip Hi,
Any response / support is expected here …

When selling top tier product (at least at from a price perspective)…any support is kind of expected. (FYI reseller also waiting for any kind of response )
Thanks.

Can you provide a .bin log with LOG_DISARMED,1 set please
I suspect it’s actual GNSS conditions, but there might be some config we can do to make life easier for the Here4

Try setting these if not already:

BRD_BOOT_DELAY,3000
GPS_AUTO_CONFIG,2
GPS1_GNSS_MODE,5

and let us know how that goes.

@xfacta , Thanks for your reply.
I will send it over tomorrow
as an FYI - I have other setup (not exact, but same cube o+ and here4) that work flawless in the same location.
I recall have tried both GPS_AUTO_CONFIG and GNSS_MODE - but i will try again and will send the log over.
Thanks again for the reply.

Looking forward to hear your conclusion.

Number of Sats and HDOP is OK, but the update rate is poor.

This should be a straight line across at 200ms (5Hz)

There’s also a bunch of config errors is the messages, like these:

You should try the update process in the manual at section 3 to see if it helps with the config errors.

Possibly related to the errors too, but mostly the poor positioning and “unhealthy” status is your location - it’s lucky that you get a position at all. Check the GPS Jam map:

@xfacta Thank you again for the reply.

Update Rate - What is the cause for that issue ? (we have lowered the constellations to only GPS/Galileo)

Erros - Gps is updated as seen in my first message in the thread.

Interferance - Yes, some times there are interferences, yet two other copters (with the same HW) are working flawless. - I believe in science not in luck.

Is there any other debugging could be done to understand why these 2 brand new unites are not performing as should ?

Thanks in advance.
