Bingo !!! You can downgrade your firmware with DJI Assistant 2
And guess what, it works like it used to on the old firmware. Home point in 30 seconds !!
It wasn't your imagination that it ran differently. And nothing to do with Cold vs Warm starts.
This isn't all good news though. In fact, I think it's bad news.
Very consistently, on V01.00.0400 it would establish Home Point at ~12 Sats.
Very consistently, on V01.00.0300 it would establish Home Point at ~8 Sats.
Now before the GPS police jump down my throat again. I'm well aware that all Sats are not equal and the requirement is not a SAT count. The requirement is an internal GPS accuracy and more Sats increases accuracy. The number of SATs just give us a rough estimate of the accuracy the receiver is getting and visibility to how the firmware labels those levels of accuracy.
It just so happens that around 8 SATS on the old firmware it had enough accuracy for Home Point.
it just so happens that around 12 SATS on the new firmware it had enough accuracy for Home Point.
It is quite clear to me that DJI increased the GPS accuracy requirements for home point and changed the "rating scale" as well. To reach that new accuracy it will typically need more Sats (or better ones).
Those accuracy requirements are now so high, they take a long time to achieve and the drone acts on those new levels. They changed the requirements drastically, in order for the end user see it jump from ~8 to ~12 to now reach Home Point. Not to mention the time it takes to achieve that.
The GPS "quality" didn't change between the different firmware revisions, the accuracy requirements did.
My Drone frequently dips to 12 Sats (old or new firmware) and takes a good while to reach 12.
But 12 is in the "Danger Zone" on the new firmware, it's well within the "Safe Zone" on the old firmware.
DJI saw it was necessary to raise the GPS accuracy requirements and now most of us are on the fringe of meeting it.
I'm now 99% sure this thing is going back. I have $4000.00 into this thing and this just doesn't smell right.
Mavic 3 is dud.
They are putting hacks in to compensate for a NEW weaker GPS system/chip design.
GPS Quality/accuracy will vary with location and time. Some users not having any issue might be in better locations and time that allowed them more margin, today. They may suffer like many of us in other locations and times, tomorrow. Those having issues today, may improve in other places and times, tomorrow. But the average looks bad based on responses.
I counted 17 seeing issues, maybe 4-5 not seeing issues.
