Pocket Mariner – Page 3 – Marine Apps and Services

Boat Beacon can now share its real time AIS feed from our global AIS aerial network via NMEA with Navionics on the same device or on the same Wifi Network. Boat Beacon acts as a “Virtual AIS Receiver” and is the first and currently only app out there that offers this .

Navionics have worked closely with us on this with their Boating app AIS feature and recommend Boat Beacon in its own category in their Boating app – AIS Devices Compatibility Guide.

The new Boat Beacon AIS Share feature is free to try. If you find it useful you can use it any time when you are out boating for a small monthly or annual subscription via IAP.

You can get the latest version of Boat Beacon from the Apple App Store here and Google PlayStore here.

This is a step by step guide on how to configure Boat Beacon AIS Sharing with Navionics on iOS (Android guide here). The guide uses Boat Beacon’s demo mode so you can try for free at home away from the coast and without having to purchase an AIS sharing subscription.

1. Launch Boat Beacon and go into Boat Beacon settings and turn on “Demo Mode”, then turn on AIS Sharing. It will show the default TCP port number to use 5353 and will be orange ( not connected). N.B. If you are not in the UK the demo mode will be centred on San Francisco bay in the US.

2. Tap Done top left and go back to the chart view. This will position the map on a virtual boat in the Solent ( or San Francisco Bay). All the other boats in view are real and live. Tap the sailboat icon bottom left to start sailing the demo route.

3. Now switch to the Navionics Boating app (on the same device) and position the Navionics map on the Solent ( or San Francisco Bay) and then tap Menu so you can configure AIS.

Scroll down to “Paired Devices”

You should then see this screen*, tap “Add Device” at the bottom.

(* If you already have a device set up you can add another by tapping the + at the top right on the device list screen.)

Fill out the Name as “Boat Beacon” ( or whatever you want to call the connection), the Host as 127.0.0.1 and the Port Number as 5353 and make sure the protocol is set as TCP.

Tap “Save” top right and go back to the map view. You should now see live AIS boat and ship icons on the Navionics map. (You need to have “Display AIS targets” enabled in the Map Options in Navionics. )

Now every time you run Boat Beacon in Sailing mode Navionics will automatically connect and receive the live AIS data from around your GPS location out to 30NM.

If you check back in Menu/Paired devices you will see Boat Beacon as Connected and AIS: Receiving data

Notes:

Boat Beacon must be in Sailing mode to maintain the AIS feed when it is in the background ( e.g. when you are viewing the Navionics Boating app) on your device.
Make sure you have Location sharing for Boat Beacon set to “While using” in your device Privacy/Location settings. Please note Boat Beacon will only use your location when it is running ( foreground) or in the background when in Sailing mode.
You do not need to have a WiFi connection to your device to use Boat Beacon and Navionics on the same device. You must have an internet connection though (e.g. Cellular/Mobile).
You can share to Navionics on other devices too if they are on the same local WiFi network using the IP address shown in Boat Beacon’s AIS Sharing setting instead of 127.0.0.1 in the Navionics Devices setting.
iOS14 has introduced a new privacy permission if apps want to use local network resources which both Boat Beacon and Navionics need to have set to yes. The OS will prompt you the first time either app tries to use a connection. You can manually set/change the permission in your device’s Settings/Privacy/Local network. See screenshot below for how we have it set.

Might sound obvious, but it has caught a couple of people out. You need to subscribe to the monthly or yearly AIS Sharing feature via IAP ( tap the AIS Sharing row in Settings to bring up the IAP screen) to use Boat Beacon with Navionics when not in demo mode.
If you have any questions or problems getting it working please email us at help@pocketmariner.com

Relocating our Portsmouth Harbour AIS aerial

For several years we have been successfully running one of our network of AIS stations in the house of Digital Yacht’s CTO, Paul Sumpner, up on Portsdown Hill overlooking Portsmouth Harbour. All of the AIS equipped vessels operating out of Portsmouth and the central Solent were picked up and transmitted over a 4G data connection to our AIS servers. The aerial position was especially important for picking up vessels in the Northern reaches of Portsmouth Harbour.

Many users of our Boat Beacon and SeaNav apps and Portsmouth International Port benefit from this data. Paul has decided to move house and area and the pressure was on to find an alternative location in time. Fortunately, following Paul’s suggestion the wonderful people at WicorMarine volunteered to become the new custodians and yesterday we went down to help them install the system.

WicorMarine Yacht Haven is located at the top of Portsmouth Harbour, with clear line of sight across the whole harbour and we hoped that the AIS reception would be as good as before.

Between the rain showers, the WicorMarine team mounted the VHF antenna on top of their weather sensor mast, while we powered up the Digital Yacht AISNet and 4GConnect router and tested that the AIS data was being received and forwarded to the internet web server.

The results were much better than we had expected and if anything we were actually getting better all round range, than previously. As you can see from the image below, 175 targets all the way up Southampton water, as far West as Lymington and way out in to the Channel beyond Nab Tower.

Everyone at Pocket Mariner, Digital Yacht and WicorMarine are very pleased with the new installation and we hope it will continue to give perfect service for many years to come.

A big thank you to Scott Waddington and his team at WicorMarine for the use of their facilities and the professional and efficient manner in which they handled this new project.

Real-time internet AIS Sharing to Navionics, iNavX, AquaMap, OpenCPN, etc. with Boat Beacon

Boat Beacon can now share its real time AIS feed from our global AIS aerial network via NMEA with other apps on the same device or on the same Wifi Network. Boat Beacon acts as a “Virtual AIS Receiver” with over the horizon coverage and is the first and currently only app out there that offers this.

Boat Beacon’s global realtime AIS coverage.

We hope this will prove popular with folks who already have other Marine Navigation apps/charts like Navionics, iNavX, Aqua Map and OpenCPN etc. which support an external NMEA AIS feed but don’t have their own Internet based AIS network or feed available.

Navionics have worked closely with us on this with their Boating app AIS feature and recommend Boat Beacon in its own category in their Boating app – AIS Devices Compatibility Guide.

The new Boat Beacon AIS Share feature is free to trial. If you find it useful you can use it any time when you are out boating for a small monthly or annual subscription via IAP.

You can get the latest version of Boat Beacon from the Apple App Store here and Google PlayStore here.

By the way, our own top selling marine charts navigation app SeaNav already has AIS built in as standard and if you haven’t tried SeaNav why don’t you give it a spin for free first, you can download it from here now https://apps.apple.com/app/seanav/id857841271 .

Here are some screenshots from Navionics, iNavX and OpenCPN using it.

Navionics connected to Boat Beacon on 127.0.0.1 TCP port 5353

On iOS

On Android

iNavX on same device ( using TCP 127.0.0.1 port 5353 )

AquaMap

OpenCPN running on a Mac via Wifi to Boat Beacon running on an iPhone ( TCP to 192.168.1.106 port 5353).

There are some simple step by step instructions on how to set up Boat Beacon AIS Sharing with the Navionics Boating app here:- https://pocketmariner.com/setup-boat-beacon-share-ais-navionics/

and here is the description in our user guide:-

AIS Sharing

Share Boat Beacon’s real time internet AIS feed via NMEA with other apps on your device and on the same Wifi network, like Navionics, OpenCPN on your Mac, iNavX , AquaMap etc. so you can see live ship positions around you on their charts as well. Pocket Mariner’s AIS service is fed by one of the largest network of AIS shore receivers world-wide covering most major ports, harbours and popular coastal areas with over 60,000 live ship positions at any time. Boat Beacon acts like a virtual AIS receiver and can also share your live position via Internet AIS with other users and internet based AIS services like MarineTraffic. After purchasing the Boat Beacon AIS Sharing IAP (monthly or yearly subscriptions available) just set your other apps NMEA TCP settings to connect to the IP address and TCP port (default is 5353) shown in Boat Beacon’s AIS Share setting. If you are sharing with an app on the same device you should use 127.0.0.1 as the IP address to connect to instead of the actual device IP address so you never have to change the setting when you are on a different network. Boat Beacon must be in sailing mode when sharing with other apps on the same device so it can track your position and continually update the live AIS data around you in the background. Tap the SailBoat icon bottom left to enable Sailing mode. In the unlikely event that you need to change the TCP port number in Boat Beacon to another number, tap on the AIS Share setting row and enter it.

On iOS you can try it out at home when there are no boats around your location by putting Boat Beacon into Demo mode ( Settings/Demo mode) first and then set sailing mode. Make sure the other app is showing the same map location as the demo mode is. Make sure to turn sailing and demo mode off when you are done. If Boat Beacon is not displaying any ships around your location then no ships will appear in the other apps either.

On Android get a 3 day free trial to try it out when you sign up for one of the subscription options. You can cancel the subscription at any time and will not be charged anything if you cancel before the end of free trial period.

Get the latest version of Boat Beacon from the App Store from here now and Google PlayStore here.

Here’s our guide on iPhone which also has some relevance to Mac. You can also export/import routes between the iOS SeaNav and Mac SeaNav app and also view them in Google Earth.

https://pocketmariner.com/create-route-seanav/

You can view the routes at any time by tapping the Navigation tab – there is a Demo route in the Solent included with the app that you can use to play with (tap the i button to view the route details and select Edit Route) :-

Simple 3dB dipole VHF AIS Marine Aerial from co-ax cable

Here’s how we make an AIS tuned 3dB gain VHF aerial using RF-coax cable.

Buy a 5 or 10m length of 50 ohm RF coax cable with bnc connectors already attached – this makes two – http://www.amazon.co.uk/dp/B00JVUP0L4. Cut to required length. Strip back the outer coating at the cut end to a length of 44.4cm + 5cm to make a loop (1/4wave for AIS frequencies). Pull the inner core through the outer sheath and lay the outer sheath back along the length of the coax and trim to 44.4cm. I add a couple of cm to the length so I can bend the tip of the inner core back on itself to hook it over something. Make sure the length of the inner is 44.4cm excluding the looped over end. Cover in heat shrink wrap if you want to make it waterproof and you have a 3dB gain AIS Aerial.

There is a useful video here showing how to do it here :-

https://www.youtube.com/watch?v=SdEglNHyHB4

and a photo of a 5m long one we made earlier. This one had a range of over 25NM when we put it on the 20th floor of a high rise in Singapore.

You could also go one step further and make a 6dB collinear like this from Neil Arundale (I have made and used one of these too and it compared equally with a £120 commercial collinear).

http://arundale.com/docs/ais/aerial.html

I hope that this inspires someone. If you get connected up please consider sharing your AIS data with us. We can provide a dedicated port and web view for your data.

The Danish charts and others can be obtained via a simple In App Purchase (IAP ) in SeaNav and SeaNav UK. All SeaNav charts are regularly updated while you have a valid chart subscription in place. You can read more about SeaNav and how to download our free version here – SeaNav

How to import lots of Points of Interest using SeaNav POI csv to kmz converter

SeaNav lets you add individual Point of Interest (POI) at a tap of the screen in the app but what about importing a list of POIs that you already have? We have set up a service to make creating SeaNav Points of Interest from a list of latitudes and longitudes easier and faster. Simply upload a CSV file ( spreadsheet comma separated values) of the POIs using this web link

https://seanav.net/charts/poi_upload.form.php

A SeaNav ready kmz file will be downloaded to your desktop which you can then share and import to SeaNav via email or Dropbox. You can also view the kmz file in Google Earth.
The format for the csv file is very simple and contains one or more lines with:-
name,type (integer 1-6),description,longitude(DD.DDD),latitude (DD.DDD)

e.g. Bass here,3,Good spot,-0.473850,50.291134
The POI types are:

1. general
2. hazard
3. fishing spot
4. diving location
5. race markers for club racing
6. favourite harbour or anchorage spot
7. bridge

These set the POI icon to be used as well.

The description can be html markup including an image link e.g.

“<img src=’http://myserver.com/mypicture.png’><br>Inlet</br>”

Be sure to wrap html descriptions in quotes as above.

Alexa Boat Beacon skill – talk with your boat

Boat Beacon now works with the amazing Amazon Alexa and Echo devices using our free Alexa Boat Beacon skill.

“Alexa, ask Boat Beacon my position”

“Sarita is travelling North East at 6 Knots in the English channel currently 5 miles south west of Plymouth”.

Or ask for “exact position” and hear : “Sarita. Latitude 52 degrees 1 minute North, Longitude 1 degree 52 minutes 34 seconds West, course 55 degrees true, speed 5 Knots.”

You can see a short 19s video clip of the Boat Beacon Alexa skill in action here :-http://boatbeaconapp.com/BoatBeaconAlexa.mp4

Just ask Alexa to register your Boat Beacon 9 digit BBSI number (without the BB prefix) to associate the Alexa Boat Beacon skill with your own Boat Beacon app and put Boat Beacon in transmit mode (sailing) to update your location, speed and course in real time.

“Alexa, ask Boat Beacon to register 617648992”

Response: “Boat Beacon BBSI 617648992 has been successfully registered. You may now ask for its position”.

You can find your unique Boat Beacon BBSI number at the bottom of Settings/My Boat Details in the Boat Beacon app on your iPhone or Android device. See the iPhone screenshot below.

Friends and family can also use the Boat Beacon Alexa skill to follow your progress when you share your Boat Beacon BBSI 9 digit number with them.

We have lots of other ideas up our sleeves for the Alexa Boat Beacon skill if it proves popular. “Alexa, ask Boat Beacon to alert me on CPA” , “Alexa, ask Boat Beacon to tell me if the wind exceeds 6 knots” and would love to hear your ideas. And if you want to know where another boat is by name or MMSI number you can use our free Boat Watch Alexa skill
