AIS receiver Page
Receiver devices and accessories equipment to track ships for marine surveillance.
AIS marine radar / navigation systems present the bearing and distance of nearby marine vessels in a radar-like display format, as well as unique identification, position, course, and speed, displayed on a computer screen, and even information about their destination, estimated time of arrival and the dimensions of each vessel.
Range is basically limited by line of sight, the relatively low power of ship transponders and the height and gain of your antenna. Typical range at sea level with a basic antenna is about 12Nm, or with a better antenna at an elevated antenna position is about 20-50Nm.
An AIS receiver requires that your PC or laptop will have loaded suitable plotting software that can understand AIS messages on a serial port, compatible with Windows XP/7/8.
To use an AIS receiver on a boat, without the need for internet connection, you will also need a VHF antenna (or a feed from an existing VHF antenna via a splitter), and a PC compatible GPS receiver (see Antenna & other Accessories page and Prices & Ordering page) or an adaptor from an existing boat GPS. Independent mapping software on your computer is still needed.
WEGMATT LLC, USA dAISy AIS receiver
dAISY AIS receiver with AIS whip (or telescopic) antenna: Part No dAISy.1kit
All you need to start tracking ships are a PC, Mac or Linux computer, and a clear view of the sea.
dAISy works with OpenCPN (free site - see https://opencpn.org/OpenCPN/info/about.html), Ship Plotter and any other software that accepts serial data input.
dAISy is also well suited for reporting local ship traffic to services like MarineTraffic and AISHub.
With it's small size, low cost and very low power consumption, dAISy is the perfect AIS device for DIY projects built around Raspberry Pi and other single-board computers. dAISy was designed around a modern single chip radio IC. This architecture is instrumental for the low price, small form factor and low power consumption, and can result in longer acquisition time, lower sensitivity and less range than commercial AIS receivers, but with a suitable antenna dAISy is more than adequate to monitor local ship traffic.
Specification· Single channel receiver
Receiving on channel A (161.975 MHz) and B (162.025 MHz)
Alternates between both channels through channel hopping (<10ms)
· Sensitivity down to -100 dBm· Very low power consumption, less than 100mW in receive mode (<20mA at 5V)
38400 baud serial over USB·
Does NOT include
0183 output - for NMEA requirement see
Part No dAISy+NMEAbelow.
· Small size: 63 x 44 x 23 mm· Sturdy aluminum enclosure
BNC connector for 50 Ohm VHF antenna supplied
· Mini-USB connector for data and power (USB cable included)
The Boat Beacon app on Android now officially supports dAISy - see http://pocketmariner.com/mobile-apps/boatbeacon/

OpenCPN, is a free, open source chart plotter and navigation software, can be used with devices like dAISy to track ships on a map. Any software running on a PC, Mac or small Linux computer that accepts AIS data from a serial input will work with dAISy. For location on map, computer will need input from GPS. (GPS dongles available from http://www.aircrafttrackingavionics.com.au ).
dAISy is professionally assembled by the manufacturer in Seattle, WA, USA, with a 12 month warranty .

Low-cost dual-channel AIS receiver with USB and NMEA 0183 output & wifi module
dAISy AIS receiver - all you need to start tracking ships are a VHF antenna, a Windows, Mac, Linux or Android device, and a clear view of the sea.
Does not include GPS, but can add separate GPS dongle - see price list GPSUSB-1 .
This true dual-channel marine AIS receiver works with OpenCPN, Ship Plotter and any other software that accepts serial data input. dAISy is also well suited for reporting local ship traffic to services like MarineTraffic.
Thanks to its two-channel design, dAISy 2+ receives twice as many messages as the single-channel dAISy. This improves acquisition time and update rate of AIS targets, while range is comparable for both models.
NMEA 0183 / RS-422 output
The dAISy 2+ AIS Receiver can directly talk to chart plotters and other marine electronics. In addition, the integrated DC/DC converter allows to power it from your boat's 12-36V power system, removing the need for a USB power source.
Auxiliary Serial Output
The serial data stream is available on a 0.1" header on the back of the unit. Users can combine dAISy2+ with a Bluetooth module to receive AIS on wireless devices, or connect a data logger like SparkFun OpenLog. The pin-out of the auxiliary serial port is compatible with the DT-06 TTL to WiFi module, which is included with this kit.

Some very useful 'Frequently Asked Questions' provided by Michael Barrett
I want to watch ships using my laptop from land,
what do I need?
.How far can I see ships?
Possible Fault remedies found by Mike,
1, Only one USB port on some Toshiba units is a high power supply. If the receiver is not receiving, you should changes to this port.
2, Plug both GPS and AIS receiver into the same
ports every time .
3, The centre box on the Opencpn tool bar is to allow the AIS to be received. You must check this box - X and red icon is replaced by no X and Green and yellow icons.
for the Safety of Life at Sea (SOLAS)
requires AIS to be fitted aboard all
international voyaging ships with
gross tonnage of 300
or more, and all passenger ships regardless of
size. It is estimated that hundreds of thousands
of vessels now carry AIS equipment.
