Raspberry Pi Embedded Cap With GPS & 10DOF

In this post we will show you how to geotag and capture the “attitude”  of photos taken with the Raspberry Pi camera and record these values within the photo itself using EXIF metadata

We used a modified (hacked?) cap to take the images in this post. The cap took photos, geo-tagged and recorded attitude as we walked around Sydney Harbour.

Components used were;

  • Raspberry Pi Zero W
  • BerryGPS-IMU
  • Raspberry Camera V2
  • A cap

The BerryGPS-IMU was used to capture the GPS coordinates as well as “attitude”.   No external antenna was needed as the BerryGPS-IMU includes an internal antenna.

The “attitude” would include values such as pitch, roll, direction. Some of this data you can see annotate in the image below.

Other programs can use some of this data to plot the image on a map and even show the direction of the camera at the time the image was taken.  A good example of this is seen in  GeoSetter

The Cap

The cap has the BerryGPS-IMU sitting on top of the visor, with the Raspberry Pi sitting under the viso.  Some holes where made in the visor to allow connectivity between the BerryGPS-IMU and Raspberry Pi.
We also created a basic camera mount out of 3mm laser cut acrylic. M2.5 Nylon screws were used to hold everything in place.

Navigating with Navit on the Raspberry Pi

navit running on a Raspberry Pi


Navit is an open source navigation system with GPS tracking.
It works great with a Raspberry Pi,  a GPS module and a small TFT with touch, jut like the official Raspberry Pi Display or PiScreen.


In this guide, we will be using;

Setting up the GPS

Navit can be installed without a GPS connected to your Raspberry Pi, but you will not be able to use the real-time turn by turn navigation. You will however be able to browse maps. If you are not going to use a GPS, you can skip to the next step.

As we are using the BerryGPS-IMU, we will be following the guide in the link below.  As most GPS modules use serial to communication, this guide can be followed for other GPS modules.

BerryGPS Setup Guide for the Raspberry Pi


The images below shows how we have connected the BerryGPS-IMU to the Raspberry Pi 3 whilst it is in the SmartPi Touch case.

If you plan on testing this out in your car,  you need to be mindfully of where you place your BerryGPS. In my setup and I have placed it in the air vent as shown below, and BerryGPS gets a good strong signal.

If you are using an external antenna, then there is no need to worry about where your BerryGPS is placed.

GPS Data logger using a BerryGPS

This post explains how to log GPS data from a BerryGPS or a BerryGPS-IMU and then how to plot this data onto Google Maps and many other maps E.g. OpenStreet, WorldStreet, National Maps, etc..

Raspberry Pi GPS

1. Setup GPS

Follow the instructions on this page to setup your Raspberry Pi for a BerryGPS. Ensure GPSD is set to automatically start and confirm that you can see the NMEA sentences when using gpsipe;

pi@raspberrypi ~ $ gpspipe -r


2.  Automatically Capture Data on Boot.

We will be using gpspipe to capture the NMEA sentence from the BerryGPS and storing these into a file. The command to use is;

pi@raspberrypi ~ $ gpspipe -r -d -l -o /home/pi/`date +”%Y%m%d-%H-%M-%S”`.nmea

-r = Output raw NMEA sentences.
-d = Causes gpspipe to run as a daemon.
-l = Causes gpspipe to sleep for ten seconds before attempting to connect to gpsd.
-o = Output to file.

The date the file is created is also added to the name.

Now we need to force the above command to run at boot. This can be done by editing the rc.local file.

pi@raspberrypi ~ $ sudo nano /etc/rc.local


Just before the last line, which will be ‘exit 0’, paste in the below line;

gpspipe -r -d -l -o /home/pi/`date +"%Y%m%d-%H-%M-%S"`.nmea

Reboot and confirm that you can see a .nmea file in the home directory.

New Products : BerryGPS and BerryGPS-IMU

We have released two new products:

BerryGPSGPS for the Raspberry Pi

BerryGPS-IMU GPS and IMU for the Raspberry Pi

Both GPS modules use the  M10478-A2 from Antenova, which is a high quality GPS module which is able to track 22 satellites and has an internal antenna. This means no external antenna is needed if the module has clear access to sky.  Both feature a SuperCap to store ephemeris data for up to four hours. This and many more features are included.

Raspberry Pi GPS




Both have been specifically designed for the Raspberry Pi Zero, however they will work with any version of Raspberry Pi.


The BerryGPS-IMU also includes all the components found on the BerryIMU.  And is compatible with the existing code in our repository. The BerryGPS-IMU present a lot of sensors in a very, very small package.
