logging nmea data

[Bikerwookie]

I am attempting to chart a local harbour using my on board system.

I have simrad nss7 with triple frequency single beam echo sounders. All this is linked to an iPad via wifi.

Does anyone know of a logging app or a way on the nss7 to log position and depth and output in a text string or nmea file?

Not on an iPad - I do have code on a Raspberry Pi that does this - bit flaky - it's still in development.

Follow up - I think it can be done quite easily just using a Windows PC with Telnet. The Microsoft telnet client allows you to log all traffic to a text file and you should be able to log into the wifi stream provided you can find out what port number the NSS7 is listening on. As an experiment, make sure you have telnet installed on a PC (look in the Windows Features section of the Control Panel), then open a command prompt window and try typing:

telnet {nss7 ip address} {nss7 port number}

if you get a connection, then you should see the NMEA stream displayed to the screen - if that works, then read the help file to work out how to turn on logging.

I use the NMEA data logger from Aggsoft (http://www.aggsoft.com/nmea-data-logger.htm). Not wildly intuitive but it has enabled me to do the charts you will see on the Updates page on my web site. Of course you have to reduce the data to a chart datum.

Thanks for the suggestions.

I have Hypack, Caris and Quinsy to log with but was after an easier way with just the iPad or NSS. Its not the software that is the issue I make charts for a living, its having to crack open the binnacle to solder a serial cable to get the nmea out. Even then it is not clear from the simrad manual if the N2K data is output on nmea 0183.

Simrad says you can log the data to the memory card but does not go any further in the manual.

Aggsoft data logger looks like a sweet bit of software though.

OpenCPN has a plugin for NMEA data logging
I think you can do it with Navmon as well ?
Both PC based of course

As another option (though you probably don't need one): kplex will do that and, if you want it to, add a timestamp for each sentence in NMEA-0183v4 TAG format. Not available for windows but there are pre-built binaries for Pi and 64-bit ubuntu and it'll compile on several other posix-like systems including mac OS X. It should also support GoFree (if your nss7 does that) meaning you don't have to muck about with sticking in IP addresses.

Have I missed something or isn't Hyperterminal (on a PC) OK?
You can run multiple sessions to save multiple instruments (NMEA timestamps will help combine them in due course) or use Angus' YAPP to combine NMEA feeds. Andrew

Unfortunately teamsurv hardware logger does not cover my area. However I will be sharing the results. I'll just send the xyz data to the uk hydrographic office for inclusion on their next update. That way all charts and s57s get updated.

Looks like it will have to be the PC route so I will be using Hypack for data collection with a tcp connection to my nmea strings over wifi.

You don't actually need the hardware.
