PX4 1.16 RC1 - no longer has COM_POS_FS_DELAY

PX4 Autopilot

I’m working through a problem with my Holybro Micro M9N gnss receiver and a Holybro Pixhawk 6C Mini running PX4 1.16 RC1.

The issue appears to be excessive sensitivity to “noise” which causes inability to arm in some modes, and failsafes from modes requiring gps. (example: position mode failsafe to altitude mode)

I’ve explored reducing the options on EK2_GPS_CHECK - down to just bits 0-4. Even with these minimal checks, I still get frequent errors. It was suggested that I increase the delay for detecting these errors but the parameter EK2_POS_FS_DELAY is no longer in 1.16 RC1. According to my inquiries, these delays are now part of the codebase.

I can try downgrading to version 1.15, but I thought I should bring up this topic in case it’s being reviewed.

I’d like to stay with 1.16 if possible - I like that it deactivates the internal compass when doing a compass calibration where an external compass is present.

Here’s a log showing the issue: https://review.px4.io/plot_app?log=60c71be8-8e70-43b1-be1a-f607a0a2621a

Thanks!
