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 Tara Holloway

I've had this for a few weeks. It worked fine. It could acquire GPS and GLONASS satellites fairly quickly (much faster than NEO6M). When I used the u-blox configuration settings it worked with this program and I was able to change the baud rate and other settings. This saves the settings across reboots. However, after a few minutes, it reverts to the default settings. I am building an Arduino based system that requires a high baud rate and refresh rate, this has made me very frustrated and now I will choose another GPS module. It works great with the default settings, but don't expect any customizations with this product.
