GPS not working

@daniel I think that's all I did, but here is my /etc/modalai/voxl-px4.config, in case you want to look for any differences:

# PX4 commands need the 'px4-' prefix in bash.
# (px4-alias.sh is expected to be in the PATH)

# Eventually there will be a utility called voxl-platform that will
# return the platform tag or an error code. This utility is not yet
# ubiquitous so it may be that it isn't available. Trying to call a
# non existent program will generate an error code by the OS. If the
# program exists and doesn't return an error code then use the results.

If your config is like this and it still doesn't work, maybe @Eric-Katzfey can help you better.

daniel

@Andre-Moura Thank You! We fixed our GPS setting problem.

JustinDev23

@daniel what ended up being your fix? I was seeing the same issues yesterday with our Sentinel trying to do GPS only outdoor flights. It wouldn't ARM due to the GPS Speed Accuracy. Flashing blue for a minute or two and then turning green after what i assumed was VIO getting healthy.

@Eric-Katzfey I don't want to use the Sentinel VIO so was hoping there was a GPS Only No VIO params file. It seems like the one posted on the git is still looking at VIO.

James Strawson

you will likely want to configure px4 params to suit your exact use case, e.g. some people will want it to arm without a gps lock, some won't. As a starting point we have "helper" files that can be loaded through QGC that set up the handful of relevant PX4 params for indoor vs outdoor flight

Here is the outdoor helper for px4 1.12:
https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-px4-params/-/blob/master/params/v1.12/ekf2_outdoor_gps_mag.params

And the helpers for PX4 1.14:
https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-px4-params/-/tree/master/params/v1.14/EKF2_helpers

JustinDev23

@James-Strawson Awesome, thanks I am going to load the outdoor params. Just didn't know if someone had already blessed us all with a known good config.

JustinDev23

@James-Strawson If i stop and disable the VIO server will that still allow GPS to pass through? I am getting good satellite and HDOP but the GPS never transitions from flashing blue to green with the ekf2_outdoor_gps_baro params. it is causing the platform to not allow me to put it in POSCTL. I do not intend to do GPS denied flights at this time and am trying to focus on outdoor 5G flights for a while to build confidence in our GCS software interactions with VOXL.

Eric Katzfey

@JustinDev23 These parameter settings won't affect the ability of the GPS receiver to get a lock. It is an independent unit and not affected by VIO in any way.

JustinDev23

@Eric-Katzfey, thanks for the response and clarifying.

I had a 3D Fix but wasnt able to switch from Manual to Position. I have worked on other projects with Ardupilot mission planner and it could blend or use best from different sources. I wasnt sure exactly how your implementation of GPS and VIO were working together on feeding positional data to the PX4 autopilot.

Andre Moura

@JustinDev23 You can have GPS fix and not have GPS lock on the PX4. Have you checked the number of satellites on QGC? From my experience, GPS lock (required to switch to Position mode) is achieved with 12 satellites or more.
Maybe test the drone on a new location with more open space, that did the trick for me.

JustinDev23

@Andre-Moura sat and hdop have not been an issue on QGC. ekf2_req_nsats is set to 6 and i have had no obstructions and in open space.

GPS Horizontal Pos Error too high with 9 sats and 1.4 hdop

JustinDev23

And if it is not that it is GPS Speed Accuracy too low

I would hate to disable those checks but i feel like it is something else that is causing this to occur.

@Eric-Katzfey Is there a flow chart for what all is feeding position information to PX4 from VOXL2?

tom

@JustinDev23 This is the closest to what you're looking for: https://docs.modalai.com/voxl-px4-developer-guide/

JustinDev23

@tom Thanks! Looks like what i needed.

@Captain-7th Are you saying that the GPS is not working? I don't see anything in the included logs to indicate that GPS is not working.

Captain 7th

@Eric-Katzfey Dear Eric,

The log shows that the voxl-px4 is does not get completed and it crashes after a while:

WARN  [uORB] orb_advertise_multi: failed to set queue size

what are these errors? after these messages, I couldn't run again the voxl-px4 again! so I decided the follow this way:

After reading some posts, I decided to upgrade the SDK version to the latest. I tried to upgrade the SDK from 1.0.0 to 1.3.0. Then running "apt update && apt upgrade"

Then, followed some hints from you that you mentioned in some other post. I found the /usr/bin/voxl-px4-start file and added these commands at the end of the file:

qshell gps stop
/bin/sleep 1
qshell gps start -b 9600

Then, in my browser (HTTP://ip.address), it shows 255 satellites, but the GPS is still blinking in red color (should it be blue color?) Also, I checked the QGS app, it does not show the number of satellites and the drone location on the map. (I am in an indoor env, but I put the drone very close to the open window.)

Eric Katzfey

@Captain-7th The connection to ground station has nothing to do with GPS. That is probably something related to your wireless network link. So I still don't see why you think GPS wasn't working.

Captain 7th

@Eric-Katzfey Could you please tell me when the GPS is working, should it start blinking blue or red? Currently, mine is red! Please also let me know how I can check my GPS is working properly or not.

Eric Katzfey

@Captain-7th That LED is a general PX4 status LED. If it is red it could indicate any number of different problems. It is not specifically tied to the GPS.
