ROLAVI HELICAL
ROLAVI HELICAL is a pocket device that works
With your Android smartphone or tablet. It can used for
Windows device too.
This is a perfect solution to get centimeter level of
precision in your projects.
Description:
The ROLAVI HELICAL is a high-precision GNSS receiver that operates connected to an
Android smartphone or tablet and you can get high precision via RTK, NTRIP and PPK. Apart
from that, the ROLAVI HELICAL has a SD port to save UBX.
This can receive data via USB cable or Bluetooth.
