Best um980 i have found
Due to my location I cannot test it performance using SBAS but, provided with RTK correction it's a great GNSS rover. The firmware can be upgraded via USB port. The 982, for it's dual antennas, is a perfect solution for a Rover device.
after 2 hours of runtime it's really hot. probably needs heatsink at the back. Tried to enable Galileo satellite corrections but FW is not recent enough
As the reset pin is missing from the breakout I don't think FW upgrade is possible.
overall it's not bad, but due to old FW it doesn't worth 5 stars
