Dual frequency GPS L1/L5 - available for Mavic?

I came across this article when reading some stuff on GPS.

Dual frequency GNSS for Android phones

It wasn't something I was aware of but apparently there is a new carrier frequency "L5" which is gradually being rolled out, which gives +/- 30cm accuracy without differential/RTK corrections.

The chipset is already available for Android phones and is not significantly more expensive than the single frequency chips.

I was wondering if anyone knew if this is a possible upgrade for DJI drones or if any current drones use a dual-frequency receiver?

It surely would be a very useful to get almost RTK accuracy without the expense or complexity.

I don't know, however there has been some discussion of this last year as I recall posting something on it. It had to do with elevation accuracy being off by 10-30 ft from takeoff to landing in a 15-20 min time frame. It would be nice if they would 'allow' us to have that kind of elevation accuracy but we just can't be trusted with that kind of accuracy.
