Like the way that it works, and how low resource it is however it never seems to get better than a 10ft accuracy. When other GPS app that connects to my generic UBlox GNSS receiver will get down to a 3-ft accuracy. So I use this app to connect to my GNSS receiver, updates frequency then switch to another one for my mock location in order to get that 3 ft accuracy.

Not sure why this app does not show up when searching for "USB GPS", I found this app through google after many days of searching. Very pleased with this app. Connects quickly and easily to USB GNSS/GPS unbox m8030 receiver set at 16hz. Stable software, no frills, straight forward gps status presentation/layout without fancy (and often lagging) visual gimmicks. Output as mock location accurately, tested with Track addict and Racechrono, works well on both. Thank you for making this great app!

Stay DGPS despite BT & NTRIP connected..... Sorry finally works by setting V1 instead of V2 for NTRIP. Get RTK fixed OK now. But no morphometric alt. Used sats=0 HDOP VDOP =0

The obvious choice for RTK / RTCM corrections / mock location from external devices. Lightweight and reliable with all needed features and no clutter.

Unfortunately does not work with Qstarz BL-818GT. It does connect to the dongle, but with 0 B/s data transfer. :-(
