# No GPS Satellites in the R2A GUI!

## Check your antenna connections on both ends.

If the status screen of you GUI is showing 0 satellites this most likely means that one end of your GNSS antenna is loose. There are three 2mm screws into the base of the antenna, unscrew those and check that the SMA cable is tight into the GNSS antenna.

Last thing is to make sure that you are using the PRI port on your LiDAR and that it is tight as well.
