PX4 Sync / Q&A: April 30, 2025

Hi

I’ve made a PR to display only the parameters compatible with the receiver in the base station menu.

I’ll be there at the Q&A to discuss it and give a little presentation if you still have time!

This PR aim to develop base station menu and depend on this PR for [GPS Driver](…https://github.com/PX4/PX4-GPSDrivers/pull/178) Description ----------- UBlox menu | Septentrio menu | Manufacturer list :-------------------------:|:-------------------------: | :---: ![](https://imgur.com/iR8IdIk.png) | ![](https://i.imgur.com/fnYAx7w.png) | ![](https://i.imgur.com/NZzPxcP.png) 1) Proposing different settings according to receiver manufacturer 2) Base Station mode change from bool to int. That will allow a future PR that have base station (for example, moving base station on boat) 3) Implement base station menu for Septentrio (base infos, base config) ### Explanation. 1) Manufacturer allow the hide and show of some settings to keep only theses that are implemented. We use bit mask defined like this : ``` readonly property var _standard: 0b00001 readonly property var _trimble: 0b00010 readonly property var _septentrio: 0b00100 readonly property var _femtomes: 0b01000 readonly property var _ublox: 0b10000 ``` To restrict a parameters' visibility to U-Blox + Septentrio : (You can use either | or +) ``` visible: manufacturer & (_ublox | _septentrio) ``` If implemented by all manufacturer : ``` visible: manufacturer & _standard ``` This parameter is always visible because it is implemented by everyone, but I think that specifying it each time avoids uncertainties such as, how compatible is this parameter with the receiver? Has the developer thought this through? Don't hesitate to tell me what you think :) To show parameters available for U-blox, set manufacturer to `_standard + _ublox` Manufacturer is set automatically when plugin a receiver. 2) Base station mode is now : 0 : Survey-in 1 : Fixed This change is compatible with the 4 different drivers that use BaseSettingsType (base_station.h). 3) a) Base stations info is display by using PosGeodetic information. b) Some parameters like Ublox min precision don't have an equivalent in Septentrio, here is a quick recap of with parameters is available or not : | Parameters | | Ublox | Septentrio | Femtomes | Trimble | | -----------------|------------------ | :----------:| :-----------: | :---------: | :--------: | | Survey-in (auto) | Min duration | ✅ | | ✅ | ✅ | | | Min precision | ✅ | | | | | Specify location | Long, Lat, Alt | ✅ | ✅ | ✅ | ✅ | | | Base precision | ✅ | | | | | | Set from position | ✅ | ✅ | ✅ | ✅ | Survey-in options don't have equivalents for Septentrio receivers. Test Steps ----------- I have followed this procedure and another intern (@Duck) have done the same on another computer. ```bash git clone https://github.com/Louis-max-H/qgroundcontrol cd qgroundcontrol git checkout pr-base-qgc git submodule update --init --force --recursive chmod +x tools/setup/*.sh docker build --file ./deploy/docker/Dockerfile-build-ubuntu -t qgc-linux-docker . ``` Edit the file src/GPS/CMakeLists.txt To have ``` CPMAddPackage( NAME px4-gpsdrivers GITHUB_REPOSITORY Louis-max-H/PX4-GPSDrivers GIT_TAG pr-base-station-px4 SOURCE_SUBDIR src ) ``` Instead of : ``` CPMAddPackage( NAME px4-gpsdrivers GITHUB_REPOSITORY PX4/PX4-GPSDrivers GIT_TAG main SOURCE_SUBDIR src ) ``` You can now build QGC using : ``` docker run --privileged --rm -v ${PWD}:/project/source -v ${PWD}/build:/project/build qgc-linux-docker ./build/AppDir/AppRun ``` - Unplug all - Plug CubeOrangePlus - Select a different manufacturer than the board tested - Select the config you want to test - Plug base station - See if : - Precision is improved, position is RTK - Information are displayed - Manufacturer is autautomaticallyt Do these steps for Survey-In, Set location Test have been made on Ublox and Septentrio, I don't have the equipment to test other GPS systems but they should work has Ublox does. Checklist: ---------- - [x ] [Review Contribution Guidelines](https://github.com/mavlink/qgroundcontrol/blob/master/.github/CONTRIBUTING.md). - [ x] [Review Code of Conduct](https://github.com/mavlink/qgroundcontrol/blob/master/.github/CODE_OF_CONDUCT.md). - [ x] I have tested my changes. Please let me know if I need to make any changes to this RP so that it can be accepted by the community, this would be my first PR :partying_face: Ps: The automatic tests could fail because of the need to modify the Makefile, so I'm putting the PR in draft form and I'll come back to you once the PR for the GPS driver has been accepted.
