EC25-E Locattion issue

I’m using EC25-E GSM module with microcontroller. I dumped code which works like grab the location coordinates and send it via an email.
It is working properly but I have to put antenna at very close to the window. In my room its very difficult to grab location coordinates.
So how can I grab the coordinates in my room…?
Is there any way to fix this…?

The module receives satellite signals indoors and is blocked. It is recommended that you enable the auxiliary positioning function, which may be better
