Intel aero RTK integration

Jump to solution

Hi

I'm working toward integrating the HERE+ rtk module with intel aero for RTK GPS testing.

I did come across the following link -

https://github.com/intel-aero/meta-intel-aero/issues/248 HERE+ with Intel RTF · Issue # 248 · intel-aero/meta-intel-aero · GitHub

which talks about the magnetometer selection (since the HERE+ has four mags I believe).

I'm not sure about the changes required to be made to the init.d startup file. Can i edit this file on my own?

 

What steps should I take after editing it?

HERE+ has following four magnetometers: HMC5983, LIS3MDL, AK09916 and MPU9250.

How can I check if these are already defined in the init.d file?

 

Also, any recommendations on which one of the mags to use (since the flight controller will only use of them at a time)?

Thanks

Ambika

Hi Ambika_Verma,

 

 

Thank you for your interest in the Intel Aero drone.

 

If you make changes to the init.d file, you may need to recompile the px4 from source.

 

I haven't tested it myself, but this guide should be useful:

Hi Alexandra,

Thanks for your reply. Will check on editing the init.d and building px4 from source.

I had another question regarding the magnetometer currently used -

1. how can I check which magnetometer/compass is currently being used? is it from the gps unit or the one available on the compute board?

 

2. i do see connections coming from the stock gps unit to the compass port, if I switch to another gps unit would i need to have a separate connection for compass?

Thanks!

Hi Ambika_Verma,

 

 

If you want to use an RTK you would need to connect it to the GPS port and continue to supply power the compass. We have not tested other modules and you may need to reconfigure the px4 firmware.

Hi Ambika_Verma,

I have also been working with the Intel Aero for a bit and may be able to provide a helpful link or two for your questions.

1. This post helped me a lot when trying to figure out what magnetometers were being used on the rtf kit as it comes out of the box: https://github.com/intel-aero/meta-intel-aero/issues/221 Pressure Sensor and Mag Sensor · Issue # 221 · intel-aero/meta-intel-aero · GitHub ; they troubleshoot for a while and go over a number of useful tricks to look uner the hood e.g. using the nuttx console built in QGC to look at what drivers and modules are being loaded).

2.The stock gps that comes with the intel aero is from Yuneec, and has a compass inside of it. in the link above, this is mentioned when they go over the fact that the stock gps uses a driver for "ist8310_ext". if you use another gps with an integrated compass, you would need a connector for that interface

https://github.com/intel-aero/meta-intel-aero/issues/221# issuecomment-319512026 Pressure Sensor and Mag Sensor · Issue # 221 · intel-aero/meta-intel-aero · GitHub (exact post where the magnetometers on the rtf kit are listed)\

hope this provides some useful information
