That Adafruit Ultimate GPS Breakout works quite well indoors. I live in 
an older house with tongue & groove roof topped by slate and plaster & 
lath walls with thick stone on the outside. That GPS usually has 8+ 
satellites anywhere in the house except the basement. Basement not as 
good, often no reception at all.
