Review on 🌍 BN-180 GPS Module: Dual Glonass GPS Car Navigation with GPS Antenna for Arduino, Raspberry Pi, Pixhawk Aircraft, CC3D F3 Flight Controller - Geekstory by Lloyd Rodriguez

You have to make sure it's literally on the window if you want to get any data at all. It is very position sensitive and will take some time to fix even if it is in a good place. Because of this, it is difficult to guess where to get it. Put it near the window once, waited 15 minutes and nothing. I moved it two inches and two minutes later it worked. With that in mind, it can be quite frustrating when you turn it on and off and move around slightly, especially since it has no memory at all. A previously made lock is lost after shutdown. Besides, it serves my purpose. NMEA statements are presented clearly and in an easy-to-read format.
