NMEA -> Wifi

I'm trying to put output the NMEA data on our sailboat to WiFi so that I can use the data on wireless devices (such as iPhone/iPad running iNavX). We currently have an NMEA multiplexer from which our instrument, gps and ais data is fed to our computer running Vista (I believe) and the Adveto nav software. Is this something I could use GPS Gate Client for? I.e., could I install it, read the NMEA data and make it available over wifi (after I connect a wifi router)?

GpsGate can easily be set to output your NMEA via TCP/IP but you would need a suitable server to receive & forward it.

As a feasibility study you could set up GpsGate on your PC to output NMEA to your free account at ( (Send) option).

Your mobile device also running GpsGate (if possible) could then be set up to receive NMEA from your account using WiFi Internet connectivity.

I have used this method the other way round to send position from my phone's built in GPS to my laptop.

Hmm, so GPSGate is not the server that I could hook into from another device on the network? Then it may not be what I need. I already have the NMEA stream coming into our nav pc (and it is used by apps on that pc). What I need is software that will make that same stream available over TCP/IP so that another app on another device on the network can listen to it by specifying IP address and port. I was hoping that GpgGate would be the solution for that.

I need to make some purchase decisions soon so any help would be worth while. GpsGate + Router would cost me $200 and getting a dedicated NMEA->Wifi box such as SeaMate lite or Digi Wi-Sp would cost twice as much (and would not be useful for sharing an internet connection since they set up a dedicated network.

Create a "TCP/IP Server" output in GpsGate, then connect over the network to that port.

Set GpsGate to receive your NMEA stream as input.
Then create Virtual COM Ports as outputs, to which you connect your GPS/navigation apps.
And create a TCP/IP Server as output, to which it is possible to connect to over the network to get the NMEA stream.

Thanks Johan,

That is what I hoped to hear. I'll definitely go with the GPSGate+Router solution then since it is much cheaper and more flexible.
