Some customers have been experiencing Russian GPS Jamming in Baltic countries, where the GPS doesn’t return to the correct location and it has to be fully rebooted. A way around this is would be to operate the units in GLONASS only mode and this is probably the easiest way to safeguard against GPS Jamming. The signals of the two types of satellites are very close together and it is extremely difficult to jam one frequency and keep the other frequency unaffected. GPS, the centre frequencies are 1575.42 MHz (L1), 1227.6 MHz (L2) and 1176.45 MHz (L5). GLONASS operates as frequency divisional multiple access (FDMA) andRead More →

Unfortunately it isn’t as simple as just downloading the app on the new Mac and transferring the data over. If you backup/transfer your old mac to a new one, sometimes the problem is that the charts are still locked to the old computer. To transfer the data across, you will need to use the Mac OSX Terminal window. You need to use a ‘command line’ command to clear out the corrupted charts directory on your new Mac. 1) Exit NavLink Uk on your Mac 2) Open Terminal on your Mac and enter: rm -rf /Users/yourusername/Library/Containers/com.pocketmariner.seanav.gb.mac.dy/Data/Library/Application Support/NavLink UK/chartSets/gb/* Replacing yourusername with the user name you useRead More →

The 4G /5G Xtream has two SIM card slots which can be manually switched between, or you can use the automatic SIM switch feature to automatically switch between them. When the automatic SIM switching feature is enabled, the 4G/5G Xtream will monitor the current SIM network and if a certain condition occurs, it will switch to using the other SIM network as detailed below. The SIM Switch section provides you with the possibility to configure SIM switching rules, i.e., set up circumstances under which the device will perform a switch from using one SIM card to another. Refer to the figure and table below forRead More →

If you have a very low internet speed (less than 5m/sec) then several factors can interfere with your internet speed. When a device is connected to one of our wireless 4G routers, the router has to “route” the data, which takes time. The typical 2.4GHz speed of 50Mbps is shared across all devices on the wireless network: more devices, less speed It is not uncommon for other 2.4GHz wireless networks to be present on a modern boat; MFD, Charger/Inverter, AIS, etc. Each network, will potentially cause interference and slower speeds To get a better speed, the best solution is to connect your laptop via Ethernet.Read More →
