Frequently asked questions about the NAVIOTAB+ system

Q. What can I do with the chartplotter?
A. You can find your position, seamlessly pan and zoom on the map, query chart objects, search marinas, locate boat ramps, wrecks and anchorages, view tides and currents with graphic display, measure distance from point-to-point and from home marker or current position to target waypoint with speed and distance values shown in miles, Nautical miles or Kilometers. You can view Latitude and Longitude, detailed object information accessible by category, and user-selectable shaded depth contours allowing users to distinguish safe waters at a glance with depth units set to user's preference in Feet, Meters or Fathoms, and so much more. With every update, which are frequent, new features are added.

Q. What is AIS radar, and how is it different from a regular marine radar that transmits, and how is it useful to me?
A. AIS (Automatic Identification System) Radar is much like the radar transponder in an aircraft. It allows the GPS position of your boat and boats around you to be automatically reported to a central database and plotted in real-time on-screen. It is actually MORE accurate than traditional radar, because it doesn't rely on a microwave pulse to range nearby objects. As you may know from radar experience sometimes you may see "ghost" echoes or other false/interference reflections in traditional radar that can be confusing or misleading.

With AIS radar, the biggest advantage is that not only can you see the EXACT position of other boats/ships near you, they can see YOU as well, because the app is also reporting your coordinates to the system as well (assuming you have an Internet connection via the NAVIOTAB+ via SIM card/account or Wi-Fi hotspot on your cellphone). This is far more effective, accurate, and safe than relying upon a radar reflector to be seen. More FAQs on operation are available The AIS radar app (Boat Beacon AIS) included with NAVIOTAB+ relies on a network of shore based AIS stations for the live ship data. The coverage is global and amongst the best in the industry, typically showing 40,000 or more live ship movements at any one time and a database of over 150,000 ships world wide. Coverage is continuously increasing and if you would like to help by adding coverage for your area please let us know. For good locations we can sometimes provide the equipment for free or at a sizeable discount to the retail price. There is more info about how to do this here - Cover your area.

Q. Do I need an MMSI identify code to run the AIS Radar app?
A. No. You do not need an MMSI to see and be seen on the AIS Radar app, but having one is a good idea, especially since it is free. Maritime Mobile Service Identity (MMSI) is a series of nine digits which are sent in digital form over a radio frequency channel in order to uniquely identify ships, coast stations and Navigation Aids. If you have an MMSI or obtain one you will be able to use AIS Boat Beacon app advanced features to share your location and be seen on other Global AIS systems maps like AIS Hub, Marine Traffic and ShipFinder etc. Having a MMSI assigned in Boat Beacon also allows you to upload klm or klz waypoint overlays to your map - email the klm file as an attachment to your mmsi"at" boatbeaconapp.com

You can also view your current track on google maps by browsing to http://boatbeaconapp.com/go/mmsi where mmsi is your mmsi number. In the US you can obtain a MMSI for free in minutes by visiting the USCG approved agent and using their online form. We can provide you with a free Boat Beacon MMSI, email us at support@pocketmariner.com. In the UK visit Ofcom MMSI You can also use a Marine Traffic pseudo MMSI number after having registered your vessel for a unique vessel's ID at this form on marinetraffic.com. Please note that the Boat Beacon and Marine Traffic MMSI numbers are not official MMSI numbers and are only used for position reporting at MarineTraffic.com and Boat Beacon. This number is NOT to be programmed into any radio equipment such as AIS transponders or DSC radio.

Q. Do I need an external AIS antenna for the NAVIOTAB+ real-time AIS radar?
A. No, it receives its data via an Internet connection normally, though optional USB AIS antennas are available. If you have WiFi or a cellular data connection enabled in the NAVIOTAB+, that's all you need for the AIS radar to function.

Q. What is the coverage area of maps that NAVIOTAB+ comes with?

Q. How does the Weather Radar App work? Is there a cost for the data?
A. The ERadar HD app uses free data from NOAA's National Weather Service NEXRAD weather radar network. It only requires 3G/4G, WiFi or cellular connectivity to get near real-time weather radar data and weather alerts for your location. There is no charge for the data. The radar app is zoomable and will also loop the last several minutes of radar imagery to show your where rain, snow, and thunderstorms are approaching your location from.

Q. Does NAVIOTAB+ have a drift alarm for when I am anchored?
A. Yes. A separate app called SailSafe Pro is installed for this. You can set a drift radius in feet. If your position exceeds that radius, an audible alarm will sound.

Q. Does NAVIOTAB+ have a depth alarm?
A. Yes. In the chartplotter, you can set a value for "safety depth" in feet, meters, or fathoms. Based on your location on the chart, if this depth is less than your safety depth, and audible alarm will sound. Note that for lakes/reservoirs with wide seasonally variable levels, you may need to adjust the value.

Q. Can you measure distances on the chartplotter map?
A. Yes. There is a button in the lower right. Simply touch it, and it will give you two pushpins. You can move these pushpins anywhere on the map and get the distance between them in the distance units you've chose in the settings.

Q. How does NAVIOTAB+ operate using 12 volt power from my boat?
A. A 12 volt cigarette lighter to USB 5 volt adapter is included. Simply plug it into the cigarette lighter/12 volt receptacle and plug in the included USB power cable which then connects to the NAVIOTAB+. This arrangement can also be used in an automobile. For boats that have 120VAC power, the included 120VAC USB power adapter can also be used.

Q. How long does NAVIOTAB+ operate on the internal battery?
