-See [[file:../setup/README.org][Main Setup]] procedures.
+Follow the [[file:../setup/README.org][Main Setup]] procedures to obtain required files from this
+repository.
+
+Install ~gpsd~, ~gpsd-clients~, and ~gpsbabel~.
+
+: $ sudo apt install gpsd gpsd-clients gpsbabel
+
+***** Setup Serial for BerryGPS
+The Ozzmaker BerryGPS-IMU unit requires that the serial console be
+disabled and the serial port enabled. (see [[https://ozzmaker.com/berrygps-setup-guide-raspberry-pi/][ref]]).
+
+: $ sudo raspi-config
+
+Navigate to ~5 Interfacing Options~, then ~P6 Serial~.
+
+When prompted "Would you like a login shell to be accessible over
+serial?", answer ~No~.
+
+When prompted "Would you like the serial port hardware to be
+enabled?", answer ~Yes~.
+
+***** Setup ~gpsd~
+~gpsd~ needs to know which serial port to look at for NMEA location
+data generated by the GPS unit. This can be done by modifying the
+~gpsd~ configuration file at ~/etc/default/gpsd~.
+
+: sudo nano /etc/default/gpsd
+
+Make sure the following lines are present:
+
+#+BEGIN_EXAMPLE
+START_DAEMON="true"
+USBAUTO="false"
+DEVICES="/dev/ttyAMA0"
+GPSD_OPTIONS="-n"
+#+END_EXAMPLE
+
+NOTE: The ~DEVICES=~ line must be adjusted if the the ~ninfacyzga~
+device is configured to also track time. (See [[file:../time/README.org::*Setup%20~gpsd~][ref]]).
+
+NOTE: The ~-n~ option causes ~gpsd~ to begin polling GPS devices
+without waiting for a client to connect. This is important if ~gpsd~
+provides data to other applications (ex: ~gpspipe~, ~chrony~).
+
+Enable ~gpsd~ to run automatically via:
+
+: $ sudo systemctl enable gpsd
+
+Restart ~gpsd~ via:
+
+: $ sudo systemctl restart gpsd
+
+Run ~gpsmon~ to verify that location data is being recorded.

 
 

-Install ~gpsd~, ~gpspipe~, ~git~, and this repository for location
-logging capability.
+: $ gpsmon
