Hi, I have M10 GPS running on Matek F405-WING v2 mounted on an aluminium boom on a 450 size helicopter.
I get error message ‘Unhealthy GPS signal’ but it’s got 18 sats and HDOP of 0.71, position on map is spot on as well.
GPS_AUTO_CONFIG,1
GPS_AUTO_SWITCH,1
GPS_DRV_OPTIONS,0
GPS_HDOP_GOOD,240
GPS_INJECT_TO,127
GPS_MIN_ELEV,-100
GPS_NAVFILTER,8
GPS_PRIMARY,0
GPS_RAW_DATA,0
GPS_SAVE_CFG,2
GPS_SBAS_MODE,2
Can somebody advise what is the problem please?
Thank You
Steve
What is the update rate? If it is below 5Hz then the signal is Unhealthy.
Where do i find update rate? I’ve looked but can’t find it 
Need to check the GPS* message time intervals in the .bin log files.
So it looks like my rate is too slow..
I’ve increase to 100mS (10Hz) using GPS1_RATE_MS and I’ll try that this afternoon.
Thank you for your help guys, much appreciated
Steve
Usually the solution is not to reduce GPS1_RATE_MS but to reduce the number of tracked satellite constellations.
But do tell us the results.
As @amilcarlucas suggests that will typically make things worse. Which M10 module is it?
The GPS is a Foxeer M10Q 250 5883 Compass GPS M10 Chip
You guys were correct, I still got the ‘unhealthy’ message and no change here…
even though GPS1_RATE_MS = 100
Should I know restrict what it’s looking for using GPS1_GNSS_MODE ? being in the UK my (INAV) choice is usually GPS, GLONASS, Galileo
Thanks
Steve
Set the rate back to 200msec and try only 2 constellations. GPS and Galileo I suppose for you.
I assume you are referring to the message being displayed by GCS? Or do you have evidence in the flight log as well?
Will do, but I don’t have access to the ‘copter again until mid-next week, I’ll report back then.
Thanks
Steve
The ‘unhealthy’ message is seen on the MP screen
The rate was pulled from the log .bin file
Please post a log when you are able to connect to the fc
