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 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-setupdocumentation/ • 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 Ethernet • Wi. Fi • • Update and upgrade sudo apt-get update • sudo apt-get upgrade • • Install Tools geany • mesa-utils • git-core cmake • gpsd-clients •

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

AIS • d. AISy module from Adrian Struder - $55 • https: //github. com/astuder/d. AISy • 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, 1 CF 4 k. T 3000 Nm`Kl@BHKJC@IH 0000, 0*37 !AIVDM, 1, 1, , B, 4028 j. OQur 1 lae. Nl. MIL@<`8 O 00@JU, 0*5 F • • Open. CPN • AIS compatible, simply open serial data connection in settings to receive information

AIS

Xbee modules • Create a wireless mesh network between devices • Satellite screens • • Share NMEA data (GPS, AIS, Radar) from the main chartplotter Sensors Wind • Weather • Temperature • • Autopilot Control (planned)
