GNSS Quectel L26-DR PSTMDRGNSA command

Hi, I am receiving the PSTMDRGNSA command when connecting my GNSS to a serial terminal but the L26-DR GNSS Protocol Specification v1.1 does not mention it, what is this command used for?

It seems that I have never seen this message.
Please help provide firmware version and save data log.The firmware version can be queried by the following command: $PSTMGETPAR,1500

Best Regards
