I have successfully incorporated the ublox NEO-M8U gps system with OPA13. it works great if placed the gps antenna correctly. what I learned from this installation are these
1) the GPS antenna need to be placed as high up in a car without much metal covering or nearby. the GPS signal can pass through plastic, glass but not metal.
2) it is important to put a metal foil at the bottom of the gps antenna to shield away from all kind of interferences from Bluetooth, Wifi, Ratio, etc. my car window tint is highly metallic dosed and it blocks away a lot of signals from external and bounces a lot of signals within the cabin. hence I was struggling getting the 3D fix. With placing a metal foil beneath the GPS antenna, it blocks all the random signal and GPS 3D fix is possible. best case, is still placing it on the external roof.
3) it is important to place Raspberry Pi away of the GPS antenna. those onboard bluetooth and wifi module can do more harm. I felt that it is better to get the RPI without bluetooth/WIFI.
