  # Fakes a GNSS fix (a loop around Bratislava, see
  # bin/gnss_simulator.rb/docs/development.adoc) since there's no real
  # receiver attached here — the "GNSS" control would otherwise just show
  # "no fix" always. Remove this service (and nothing else) whenever a real
  # receiver/gpsd setup replaces it. network_mode ties it to maptool's own
  # network namespace rather than a bridge network, since GpsdClient
  # connects to a hardcoded 127.0.0.1:2947 — same as gpsd itself normally
  # being local to the machine it serves.
