Do you mean this one? http://www.proficnc.com/all-products/163-gps-module.html
No. It has Android device built-in, our Android app supports DJI drones only.
Alexey, Yes that one.
Do you think it would be possible to upload the UgCS mission via direct USB connection on the ground and then fly the waypoint mission while monitoring on the Android running Qgroundcontrol or similar app?
Yes, why not. After mission upload from UgCS you can connect to the drone using Herelink and download mission into QGroundControl.
I can't find any documentation for this device. May be it can bridge own connection to the drone somehow?
Alexey, Sounds good. I will try this out and report back with my findings. Thanks!
