@kestrelsystemsbp Take a look at Python MPA interface: https://gitlab.com/voxl-public/voxl-sdk/core-libs/libmodal-pipe/-/tree/dev/python?ref_type=heads

@kestrelsystemsbp ,

Thank for clarifying. Indeed the camera-calibration app does not work well for high resolution camera calibration because the processing is not optimized for the large image size (takes too long to process a frame).

The workaround for now is to use down-scaled image for calibration. I will follow up with instructions for the easiest way to do this.

@tom It's okay, I managed to figure it out. Just had to change the RC protocol in the px4-conf file.

@tom That did the trick, thanks for the help!

Hi @kestrelsystemsbp , the GPS interference is an ongoing investigation and there are several threads about this on the forum. For Starling 2, we found that moving the wifi dongle to a different location (or offsetting the GPS receiver) helps with interference (it is located right under the gps receiver). Also, elevating the gps receiver and shielding, should help. Please also read through the following discussion related to Starling 2 Max : https://forum.modalai.com/topic/4226/starling-2-max-no-gps-data/

I am not saying that you need such a big mast, but you may need to experiment a bit to figure out how to improve.

I am sorry for the inconvenience and let me know if you need any guidance for checking the signal strength, as described in the other thread. You do not have to use the live streaming plot for checking the individual signal strength -- you could do it directly using the terminal.

In open sky conditions, you should have a number of satellites above 40dB (which is not the case in this example i just pasted above). You can see the examples of the good and bad signal in the Starling 2 MAX thread i mentioned above.
