[FOSS-GPS] Amateur NTRIP casters

[John Morris]

I'm setting up a small ntrip caster which runs on a RaspberryPi. It takes data from an Lea-Xt and  can broadcast both raw and RTCM 3.1 messages.  It doesn't support all the variations of Ntrip - just Ntrip 2 over tcp with simple password protection - but that is all I need for my purposes.

Over all, I'd like to set up a series of local, community base stations, and then do a mobile app for short static positions. I haven't started the mobile app yet, but the base station software is close to being usable.

I'd be interested in collaborating.

I have seen some things about NTRIP casters as references.  They're
supposed to be useful, but few and far between.  Long-distance baselines
are likely.

I was talking to a local ham radio group the other day, which was into
setting up stations... repeaters I think, as a grassroots public
service.  I think there was some sort of internet connection involved there.

Would it be useful to use something like LEA-6T or NV08-C L1 stuff as an
amateur, but more likely to be local (low baseline), NTRIP caster?

It really doesn't seem difficult to add this functionality to the sort
of physical stations they do.  Is it useful for accuracy?  Is there an
existing framework by which amateur, local NTRIP data could be located
and accessed?
