Connecting older RADAR & GPS to a tablet.

[Uricanejack]

I was just wonder if this is possible and what you need to do it.
Thought I might as well start a new thread after reading the AIS thread. Not sure if I want to fit an AIS. If I did. I would want a more integrated rather than stand alone. Cost wise stand alone might be only option.
The RADAR is now out of production a 1712 and GPS is quite old as well. I don't have a plotter. Both work just fine. So it seams silly to replace them. Particularly since my budget is quite tight.
The idea would be to use a tablet instead of a plotter. I was wondering if the GPS info and RADAR could be input and displayed by a tablet. I have heard there are chart programs which can be used to display electronic charts on the tablet.

I've answered most of this a few minutes ago on the AIS thread.

I don't think you will be able to get radar on the tablet but AIS and GPS is not difficult using wifi as described on the other thread.

I have charts on my tablet and overlay the AIS data as here from just off Venice last July.

Schematic of my setup below, which is probably way beyond what you want and no doubt no bit intimidating if you're not into techy stuff.
For you it might be well worth looking nat something like a standard horizon gx2100 or similar, and maybe a remote mic for the cockpit. Little bit power hungry at around 0.5a standby but it means you get ais and DSC from one box and antenna.

I use a Sony Xperia tablet, lovely piece of kit, with a chart plotter app called Opencpn. Then a really cheap little computer called a Raspberry Pi takes the gps and ais signals and spits them out over wifi for the tablet to display.

There's an error in the schematic, the raspberry pi can't do email offshore using the ham radio, need a windows laptop for that.

Radar not possible as far as I know.

Thanks. much to my surprise I managed to copy your schematic.
It does have more on it than I was contemplating. I am definitely not an up to date techy. so it will still take some thinking.
Pitty the RADAR wont work.
GPS and AIS on a tablet might be a good plan. Like you say if the need arises you can still go look at the RADAR.

Thanks
I am assuming you have GPS into it as well or does your AIS have a GPS.

I have GPS connected to the chartplotter and GPS integrated with the AIS (all AIS transceivers must have this) and the signal from either of them can be broadcast over wifi by the AIS unit. I use the GPS built into the AIS unit and send that to the tablet as it's the AIS data I'm really interested in so that must obviously have to be turned on whereas the plotter might be off.

There's also a GPS chip in the Android tablet, of course, which I can use with the charts if I just want to navigate without AIS.
