2) Send corrections to your GNSS receiver from in-built NTRIP Client (V1 & V2), and PointPerfect
3) Output your GNSS receiver data to NTRIP Server (V1/V2), TCP Client or TCP Server

Ratings and reviews

I can connect to NTRIP and external GNSS devices great. The only problem is that I believe the app is intended to allow re-serving NTRIP (eg, an NTRIP Proxy). However, the "Receiver Data Output" which appears to provide that capability, doesn't function in that manner. If I'm wrong, please post details to help other users and I'll update my review. Thank you!

not sure why this app does not show up when searching for "USB GPS", i found this app thru google after many days of searching. very pleased with this app. connects quickly and easily to USB GNSS/GPS u-blox 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 Trackaddict and Racechrono, works well on both. thank you for making this great app!

Finally a supported RTK App! Works like a charm. Only bug I've found is that after the first start, the permissions were requested (and granted) but the app showed an error that permissions were not correct and only showed an empty screen. After completely closing and reopening it, everything worked.
