If there is no GPS signal, the drone will enter ATTI mode and an additional message about ASA mode will be written to the log. What is the difference between these modes?

This is a fragment of the log:

U 03m 40s 68.0 m 719 m Low Risk Weak GNSS signal. ASA mode activated. Drone cannot hover. Fly with caution (Code: 30022). Low severity, impact on safety is likely not significantDrone in ASA mode. Positioning is impossible. Fly with caution (Code: 30004). Insufficient lighting. Vision and recognition system

That just sounds like Atti Mode

I almost missed you posted the flight, so much of I can't read, but there IS a Atti in there.
Hummmm, I have my thoughts.
I'm not a good annalist like others, I will watch.

Here is an example of spoofing
This is what the flight looks like, the drone does not respond to the sticks, only rotation around the axis is possible.

Hi, welcome.

Can you share the log of this flight? So interesting.

But these are different messages and I would like to know what ASA means.
"Mode changed to Atti" "ASA mode activated".
It's Atti Mode but the language has screwed it up.
If the flight was done with an English language version of the app, it wouldn't make any mention of ASA.
There is no such thing as ASA Mode.

Это Atti Mode, но язык все испортил.
Если бы полет выполнялся с использованием англоязычной версии приложения, в нем не было бы никакого упоминания об ASA.
Режима ASA не существует.
No, it is not. The English version has the same message.
I have tested it and found different behavior. In ATTI mode, the drone does not hold the position of the lower sensors.
In ASA mode, at low altitude, the lower positioning system works and the drone stabilizes.

I've not seen that message in 10 years of flying the English version of the apps.
There is Atti Mode and Opti Mode, with Opti Mode being Atti Mode + VPS.

Opti Mode
Opti Mode ? Is this message also written in the log? Can you give an example? Based on your information, it is possible that this is the ASA in the version for other countries.
"Opti Mode being Atti Mode + VPS" this is exactly what I observe.
I have only encountered Opti Mode in the GO 4 app
 
HUM?

0m 13.8s Flight Mode goes to ATTI Note the satellite count.
1m 1.9s Flight Mode goes to P-GPS

"If there is no GPS signal, the drone will enter ATTI mode and an additional message about ASA mode will be written to the log"
Where is the log file that has "ASA"?

Also, I assumed you where posted in this section for others to help identify why there was a crash?

There is a message about ASA mode in the log, but it is in Russian, but it is not ATTI)
I have provided the translation earlier.
The reason for the crash is clear to me and does not require explanation, it is spoofing.

"spoofing" ?
I use that word like, they are spoofing a phone number.

You must be meaning spinning?
If you know why the crash happened Thumbswayup 👌

GPS spoofing is sort of the same thing:

"GPS spoofing involves the transmission of false GPS signals to trick a receiver into thinking it’s in a different location or time than it actually is. Unlike simple jamming, which merely blocks GPS signals, spoofing creates a false reality for the targeted device."

@waynorth Thanks!

I'm making the connections now, I'm sure it does exist.
I really don't know much about Russia.

I will stay in the back ground. 👌

Hi,

I believe you are referring to this warning. This was shown at 13.9 sec of the flight.

The direct translation of the warning is:
Aca Mode. Be careful.; Positioning is impossible. Be careful (Code: 30004)

Immediately afterward, the drone turned to Atti Mode.

Some other Russian speaker pilot also seems to support that ACA mode and Atti mode are the same:
