Quark-Elec AIS receiver review and Boat Beacon

Hot off the presses at Pocket Mariner a fantastic new review of our receiver working with their software.  They compared it with some other top sellers and their conclusion was:

 

If you are on a small boat and your AIS aerial is at most 10m above sea level the VHF ship spotting horizon range will be about 12NM (see note at end on calculating VHF horizon range). The Quark easily met that target for spotting ships.

Customer Video of QK-A026 set-up

Jim Ferguson aboard the Mischief Managed recently purchased a QK-A026.

He made a YouTube Video Guide to setting it up and had some really nice things to say about it:

After I bought this I had really high hopes for it.  As it turns out my hopes have been mostly realized.  I can connect iNavX on my iPad and MacENC on my Macintosh computer wirelessly and receive GPS and AIS data while the A026 is happily providing AIS target data to my Garmin GPSMap 3206 chart plotter.  Anyway, I am ecstatic with the way this has worked out. 

Simple guide to AIS Receivers

AIS Receivers – Why do I want one? Which one do I need?

 

Why do I want one?

AIS, which stands for Automatic Identification System, is a convenience which is becoming a necessity.  As a part of the safety suite of your small vessel it cannot be overstated how useful having AIS can be.  Although not yet mandatory, it is a natural partner to GPS and other navigation aids to augment your perception of the water around you.  In increasingly crowded waters, it is easy to stray into shipping lanes, with AIS it will be that much easier to stay out of danger.

 

It comes in 2 main types: Class A, which is mandatory for ships over 300 tonnes and passenger vessels and Class B, which is optional for everybody else. Class B is what we manufacture and they also come in two flavours: Transponder and receiver-only.  We specialise in receivers for the leisure and coastal fishing market.  These will collect information on shipping around you but don’t transmit any information from you.

So, what do they do?

 

The principal purpose of AIS is to enable everyone on the water to avoid everyone else.  Which, when the weather is against you, can be difficult to say the least.  The Class A Transponders are required to transmit a considerable volume of information but it boils down to who they are, where they are, and how fast they are travelling.  Our leisure models take advantage of this to receive these signals and use them to plot who’s where in the environment around your boat.  This is not a replacement for looking out of the window, many smaller vessels may not have AIS transponders and will not be transmitting, but it will plot all the larger shipping and (hopefully) keep you out of its way.

 

Staying with the ‘thing of two’s’, receivers also come in two types; channel hopping and dual channel.  Transponders transmit on two frequencies; 161.975 MHz and 162.025 MHz. Channel-hopping uses a sophisticated algorithm to listen to both AIS channels alternately and then combines the information, dual channel listens to both channels simultaneously.  The main difference is that dual channel receivers process the information faster as they are picking up all of it at the same time, this allows for faster plotting.  Equally, with channel hopping, it is possible to miss some messages while the unit is listening to the other frequency.

 

AIS works on a VHF signal and often the best choice is to install a dedicated antenna separately to the radio antenna.  However, for various reasons this may not be possible or desirable so signal splitters are available, however, the sharing protocol means no AIS signals will be picked up whilst you are using the radio. It is not good practise to rely solely on WiFi  under any circumstances.

Which one do I need?

 

We currently manufacture five AIS receivers. Two are channel-hopping, three are dual channel, all have a range of 55 nautical miles (LOS), work with Windows, Mac and Linux Laptops, work with chartplotters, output NMEA-0183 messages at 38400 bps on USB, are powered by USB and calibrated to a sensitivity of at least -106dBm at 30%PER. All but one interwork with GPS and that one has in-built GPS.  Three have WiFi and can output NMEA-0183 messages on that and two have RS422 connection as well.  

 

That’s a lot of information to take in so here it is in chart form:

[1] Next upgrade should increase this to -110dBm.

The A021 is a dongle about the same size as a large memory stick, the A022 and 23 are around 2” across (5cm) and less than ½” tall (1cm approx) so all three can be slipped into a pocket and taken anywhere and connected in the field.  (Is it still a field if it is on water?)

 

The A024/26 are a little larger, but still very portable. All are straightforward to integrate into your systems.  All but the A021 come in sturdy aluminium enclosures and the A024/6 has fixing lugs for permanent positioning.  

 

The choice is yours! The very economical option of the A021 is a chance to dip a toe in the water for £41.99 (+P&P), more features are added as you go up the range and are priced accordingly but  if you already know you need the sophistication of the A026 it is also competitively priced at £106.79 (+P&P).

Fantastic product A026

Jan. 30, 2017

I stumbled across this product while searching for ways to get AIS into OpenCPN with my Raspberry Pi. Not only does this provide AIS, but also GPS and connects to. NMEA 183 and routes that on wirelessly! I can’t believe it’s all there for a phenomenal price.

Excellent receiver

Feb. 26, 2017

Bought this unit at my first attempt of receiving AIS broadcasts. I was on the lookout for a dedicated dual channel AIS receiver of good quality and reasonable cost. I was not disappointed. Excellent service and fast delivery. The unit works perfectly.

Great product, works fine, excellent experience, we see important ships information and at moment works very well.

Shipping with no delay and client support works great.

Thanks guys.

Miguel, Portugal

 

Fantastic receiver. Almost as good as shipboard.

Nov. 16, 2016

I was so surprised at its size, especially for a dual channel receiver. The sensitivity and selectivity are excellent. Channel selection is automatic, no operator intervention required, it is truly plug and play. The performance of this receiver makes it worth at least 3 times the price.

AIS receiver QK-A023

Jan. 13, 2017

I am absolutely satisfied with the QK-A023 so far.

It was easy to install and to integrate into OpenCPN . Both connections, USB and Wireless, worked seamless and without any problems.

I have only tested the receiver at home which is a few kilometer away from the next ships but even with a home brew VHF emergency antenna the reception was brilliant. I could see every ship that was announced by marinetraffic.com. I am looking forward for the new sailing season to use the device on my boat.

 

Brilliant product!

The QK-G025 in Electromagnetic Valve and Pump applications

Applications

The QK-G025 module is an industrial grade product which is designed to provide remote control of pumps, valves and pipelines. As it can work in two modes, Dead Man and Timed Pulse, it can be used for a wide variety of remote applications. The two alarm inputs provide another mechanism for automatic remote monitoring and can act as either switches or input sources, ensuring your liquid/gas transit or storage system is entirely controllable from wherever the operator needs to be. The inputs can be from a wide variety of sensors, e.g. photocell receivers, CO2 monitors, leak detectors etc.

As you can set the QK-G025 up without a PC, it is easy to install in remote locations, you just need a power supply, a registered SIM and a phone signal. Access can be granted to up to four numbers, and incoming calls from any other number will be disregarded so your controller is secure from outside interference. In addition to controlling your system automatically or remotely, it can be interrogated by SMS for status updates. As the unit works on number recognition, the call is never answered thus the system is Toll free in use.

 Advantages

  • Secure, uses caller ID for identification, unknown callers are ignored.
  • Alarm inputs for automated control.
  • Dual working modes, ‘Dead Man’ and time pulsed for remote operation.
  • Easy to install and configure (no PC required).
  • Up to 4 mobile phones per unit.
  • Request status via SMS.
  • Compatible with all major GSM SIM networks.
  • Tri-band GSM for use in Europe & USA.
