relaying data from buoy via land-based GOES


jankplus Nov 16, 2015 04:13 PM

I've got a buoy that communicates via RF401 with a local field station's laptop, running LoggerNet. Both the station and the buoy are very remote, beyond the reach of cellular signals. The field station has satellite-based internet which we use to ftp the buoy's datafiles on an hourly basis but the sat internet is flakey and has frequent outages. As of right now it's been down for 12 days.

At other sites in the past I've connected a CR1000 and TX312 to use GOES for hourly data messages, but this was on a stable platform mounted in shallow water on the ocean floor and the buoy I'm talking about is too bouncy to connect to satellites in this way.

We're wondering if we can use GOES as a backup for RF/ftp, just for some high-level hourly numbers. In this case the CR1000 is on a buoy and the GOES transmitter/antenna would be on land. Is there a way to make this work? I'm guessing we'd need a second datalogger on land with a GOES transmitter, and somehow connect the two loggers via RF, but what would this second logger's programming look like, and how would the two loggers need to communicate? Or is there a simpler approach?

Any ideas/suggestions would be most welcome. Thanks.
