This will show how to setup a raspberry pi to upload an image including GPS location to a server. 







# 1 > REQUIRED DEVICE: Raspberry Pi

You will need a raspberry pi version 3





# 2 > REQUIRED: GPS HAT (version A)

This is the gps HAT that can be mounted directly on the raspberry pi

PURCHASE: Adafruit Ultimate GPS HAT for Raspberry Pi A+ or B+ - Mini Kit

NOTE: ensure you also purchase the GPS antenna connector (not the antenna, but the wire the WILL connect to your antenna

You will also need an ANTENNA
GPS Antenna - External Active Antenna with SMA to u.FL Cable Assembly





# 3 > REQUIRED: GPS usb (version B)

Optionally you can use a USB gps device to connect to your raspberry PI

Stratux Vk-162 Remote Mount USB GPS

 





# 4 > Install raspberry PI

You should follow other in depth instructions to install a raspberry PI
-> Here are the step by step instructions

sudo apt-get update
sudo apt-get dist-upgrade
raspi-config

Configure wifi,etc

sudo reboot
ps axf
sudo raspi-config
ifconfig
sudo /sbin/shutdown -h now

deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi

sudo apt-get install php5





# 5 > Install software

Setting up the software is straight forward and easy 

#Paste this into your command line

sudo apt-get install subversion && svn export https://github.com/sacha-lewis/offlineBox/trunk/raspberryPi/install.sh install.sh && chmod +x install.sh && ./install.sh

This will download all the files needed from github and run the install command
-> remove install if you want to read the source before proceeding





# 6 > Install GPS

Plug in your GPS device using USB OR connect your GPS hat to the Raspberry PI

lsusb

Ensure you see the GPS module in the list
-> In our scenerio we have U-Blox AG

Bus 001 Device 006: ID 1546:01a7 U-Blox AG
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

#reset
sudo killall gpsd

#now to test
php testGps.php

#You should see lat/lng information in the output





# 7 > Setting up server

Create a PHP file on a server: raspberry.php

//VIEW the post information

$this->writeToLog('raspberryPi.log', 'Receiving a new packet...', TRUE);
//$this->writeToLog('raspberryPi.log', 'POST: '.json_encode($_POST), TRUE);

//lookup the IMEI
//write a new marker

$lat = $_POST['lat'];
$lng = $_POST['lng'];
$course = $_POST['course'];
$imei = $_POST['imei'];
$date = $_POST['date'];
$speed = $_POST['speed'];
$gps_valid = $_POST['gps_valid'];

$imageName = $imei.date('YmdHis').'.jpg';
$image = $_POST['picture'];
$image = base64_decode($image);

#save the image to the server
file_put_contents($imageName, $image);

$this->writeToLog('raspberryPi.log', 'lat: '.$lat, TRUE);
$this->writeToLog('raspberryPi.log', 'lng: '.$lng, TRUE);
$this->writeToLog('raspberryPi.log', 'imei: '.$imei, TRUE);
$this->writeToLog('raspberryPi.log', 'date: '.$date, TRUE);
