From 4d3b80c338f34d7dc9516e7cdff7782aaf922b9c Mon Sep 17 00:00:00 2001 From: Moritz Fischer Date: Fri, 1 May 2015 12:17:10 -0700 Subject: e300: gps: Keep antenna power supply and pps running all the time. This is a change from behaviour so far. Before the GPS was only on while UHD is running. This behaviour was confusing users, and didn't match our other devices.
