Mavic Mini drifting

[CroatianMavic]

Hello,

i noticed my MM is drifting quite a bit when above sea. It’s not ascending or descending, just going in the direction of the wind(breeze). When I fly above beach it stays rock solid. I think that gps should hold its position a bit better :/ Do you guys have a same experience?

Sound like it's too windy to hold position and therefore drifting with the wind. It's a mini don't forget

its not too windy. I have 250 flights with it and it never does this thing when above solid ground and in much stronger winds. When I ascended today to 120 m it was rock solid. It only happened when 6-10 m above sea. Had 13 sattelites and no interference.

perhaps it was lower than you show on app and it is trying to hold its position using optical sensor? If it happens only in lower altitude that is a strong option. Another cause can be the fact that GPS signals can be reflected (as all radio signals) and near to a such reflective body like water the IMU does a hard work to determine the rigth position.

The explanation is on p16 of your manual.

yes but a question still remaiins... it is always use the Vision System for position holding (under, say, 10m) or when it has strong GPS signal it use Vision System only for smart landing?

It's no question.
The OP proved it for himself.
When he was down in VPS range, the VPS attempted to hold position and failed.
When he climbed above VPS range, the drone was rock solid.

btw .. GPS reflection isn't the issue.
Without VPS, DJI drones easily hold position close above water using just GPS.

Yeah I know that vps is affected by water but I find insane that I have to tape my vps sensors if I want to fly <10 m above water. Logically it should switch to gps hold if it senses movement without stick input when in vps mode.
Thank you guys for answers
