About ZephrFix

ZephrFix turns your Android phone into a professional-grade GNSS position source — delivering sub-meter accuracy using cloud correction streams (PPP/DGNSS), with no dedicated hardware needed. Position data streams at up to 10 Hz over TCP or Bluetooth SPP in standard NMEA format, making it a drop-in replacement for expensive GNSS rovers in ArcGIS Field Maps, SW Maps, Mapit GIS, FieldGenius, and any other NMEA-compatible field software.

Free tier uses standard Android location. ZephrFix Pro unlocks the Zephr positioning engine with Zephr corrections. ZephrFix Pro+ adds Rx Networks premium corrections, available in the US, Europe, Japan, South Korea and Taiwan.

Team mode (experimental). See nearby teammates' positions and talk with push-to-talk, with no cell service or server needed. Phones connect directly to each other over Wi-Fi Aware, and everything is encrypted, so only invited teammates can see it. Needs a phone that supports Wi-Fi Aware.

Turn on experimental features by long-pressing the ZephrFix name at the top of the Home screen.
