That's an old receiver.  Modern receivers are much more sensitive and much 
more likely to work indoors.

I suggest getting a modern chip.  Some of them come packaged with an antenna.

Then you can play around with it from a PC, arduino, or Raspberry Pi to 
figure out what you will have to do and how well it will work.

Here is one to consider:
  Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz updates - Version 3

If you have room on the display, you can display the offset between the time 
as derived from GPS and the time from the power line.  :)

These are my opinions.  I hate spam.
