Used to create a PTP/NTP server. Worked great indoors too. It takes approximately 2 minutes to acquire a GPS signal indoors. I haven't tested it outdoors, but it's a very reliable card. I was able to get it up and running very quickly using a Raspberry Pi 2 and a Raspberry Pi 3 B. The Pi 3B was more of a challenge, but I overcame it after a few hours of fiddling. Even if it goes well with the smart case.
