Your USRP-E Series device comes with an internal GPS.
In order to get a lock on a satellite an external GPS antenna is required.
+The PPS from the internal GPS can be used to discipline the internal reference clock. This feature is automatically

The device provides a 3.3V supply voltage to an external antenna connected to the *GPS* port
of your device. Note that this supply voltage is turned off in order to safe power upon destruction of the software object.
