Building your own Chartplotter with AIS, Radar, & Autopilot Matt Brown

So who the #&^*!$ is Matt Brown Been coding since 1983 Attended Pacific Lutheran University Majoring in Earth Sciences and Computer Sciences Minor in Mathematics Professional Software Developer since 1994 “Real” Boat owner since 1998 https://mvcesc.files.wordpress.com Self-described maker and tinkerer

No really, who is he? That guy!

So why are we here?

What the #&^*!$ was that? Hardware Software Raspberry Pi 2 “Puck” style GPS dAISy AIS receiver from Adrian Studer Television Software Raspbian OS and Debian packages OpenCPN chartplotter and navigation software NOAA Charts RaspBMC

No. Really. What the #&^*!$ was that? An extendable chartplotter GPS Location AIS targets

Can’t I just buy something and put it on my boat? Of course you can Simrad NSS9 $4,198 NSS8 Sport $2,100 Raymarine A78 $2,299 Garmin 92sv $1,999 This system Around $500

Can’t I just buy something and put it on my boat? Hardware Raspberry Pi 2 $35 “Puck” style GPS $40 dAISy AIS receiver from Adrian Studer $55 Keyboard, USB Wifi modules, Cables, case, etc $50 Television $100 - $300 Software Raspbian OS and Debian packages - Free OpenCPN chartplotter and navigation software - Free NOAA Charts - Free RaspBMC - Free

About the Raspberry Pi It’s a credit card sized computer, that plugs into a TV (HDMI), designed to teach kids how to program Well supported by online community Now used by hobbyists as well as professional engineers to build integrated systems Latest version 900Mhz quad-core ARM Cortex-A7 CPU 1GB SDRAM 1080p HDMI video (VideoCore IV 3D graphics core) Micro SD card slot Equivalent to a top of the line desktop computer circa 2004

Alternative SOCs to the Raspberry Pi Banana Pi $45 1Ghz dual core ARM Cortex-A7 CPU Mali-400 MP2 GPU 1GB DDR3 CubieTruck $85 2GB DDR3, 8GB NAND flash + microSD slot Onboard Wifi, Bluetooth, Ethernet, 2 USB ports Beaglebone $60 1Ghz ARM Cortex-A8 CPU PowerVR SGX 2D/3D GPU supporting dual displays

Alternatives to the Raspberry Pi iPad $500 64bit A8x CPU 10” screen Bluetooth GPS receiver ~$70 Navionics Navigation Suite $10-$149 Laptop $300+ Specs vary USB or Bluetooth GPS receiver OpenCPN capable Android devices $100+ May need Bluetooth GPS receiver ~$70

What Does It Do? Chartplotter GPS Location

What Does It Do? Weather Overlay AIS Data

What Does It Do? Ships & Maintenance Log Route Planning

What Else Can It Do? Autopilot Radar Overlay

What else can it do? Fishfinder Simple Computer Movie and Music Player Web browser Email client Basic business apps Messaging Apps Movie and Music Player Camera System

Building the System

Building the System Complete step-by-step instructions at https://mvcesc.wordpress.com/2013/09/20/detailed-raspberry- pi-setup-documentation/ Download OS Image from the internet Burn OS image to micro SD Card Install SD Card, Keyboard, Mouse, HDMI Cable, USB GPS, USB AIS Boot Expand File System Set to US Boot to desktop Reboot

Building the System Connect to Internet Update and upgrade Ethernet WiFi Update and upgrade sudo apt-get update sudo apt-get upgrade Install Tools geany mesa-utils git-core cmake gpsd gpsd-clients

Building the System Download charts from NOAA Raster (RNC) vs Vector (ENC) Pull code down from the internet git clone Compile and Install cmake, make Run and add charts -unit_test_1 Install additional plugins Watchdog Logbook

AIS dAISy module from Adrian Struder - $55 https://github.com/astuder/dAISy Channel hops between A (161.975 MHz) and B (162.025 MHz) Serial data stream (9600/8/N/1) NMEA 0183 sentences (AIVDM) !AIVDM,1,1,,A,1CF4kT3000Nm`Kl@BHKJC@IH0000,0*37 !AIVDM,1,1,,B,4028jOQur1laeNlMIL@<`8O00@JU,0*5F OpenCPN AIS compatible, simply open serial data connection in settings to receive information
