LTAP mini and GPS

Hi
I can not find in the command menu system GPS.
My LTAP mini is this one:
Modem
manufacturer: MikroTik
model: R11e-4G
revision: R11e-4G_V005

system routeboard print
routerboard: yes
board-name: LtAP mini
model: RB912R-2nD
serial-number: 9E0409xxxxx
firmware-type: qca9531L
factory-firmware: 6.43.3
current-firmware: 6.43.3
upgrade-firmware: 6.46.6

and there is a 9-pins serial port
Can you please explain me why I do not have this option in the menu??

Make sure you didn’t install only some selected packages upon upgrade, or maybe did not disable GPS package in the “system packages” menu.
Upload this and reboot it:

Hi again and thank you for your quick answer.
I uploaded the linked file and rebooted the router but still no system gps command is available.
here is the result of system package print command
[admin@MikroTik] > system package print
Flags: X - disabled
