INS drift and correction

[Red_Camarada]

Hi everyone, I was flying with some friends a mission dated before the GPS (1990) and noticed some INS error, the TGT WP were 2.5Km off:

1 - Is INS error/deviation modeled?

2 - Is there a way to correct this deviation?

thanks

1) Yes
2) No, not yet.

Yes, this makes flying and navigating in GPS restricted conditions quite painful, especially on longer flights.

Interesting, didn't experience this so far.

@QuiGonwhat kind of GPS restricted conditions would this be? I am not aware DCS has a kill switch for GPS reception.
I think the longest flight I had so far with the Apache was 3+ hours on the Syria map and there was no noticable drift.

There are two ways to disable GPS currently:
1) Set the mission date prior to 1994
2) Fly on non NATO coaliton and have the UNRESTRICTED SATNAV option disabled in the difficulty settings

Thank you!
