[FOSS-GPS] Ntrip servers and casters?

[Joseph Reeves]

Dear all,

I was talking with Juan Lucas Domínguez Rubio this morning, asking
what improvements Juan Guillermo Jordán's libLocation would make to
his unofficial gvSIG Mobile port:

One of the improvements I was told about was access to Ntrip data,
which I'm particularly interested in. I've seen sites such as:

http://www.ntrip-systems.com/

Which would happily sell me an Ntrip server and caster that I would
just need to plug an (expensive) GPS receiver into, but does anyone
know of software I could download to perform the same role?
ntrip-systems' products are all linux based, so I'm guessing there's
likely an alternative available to run on my home server. Hardware
could be an issue, however; does anyone know of any consumer receivers
that could provide the appropriate data?

Apologies for not looking into this in great detail before sending an
email to the list, but I was hoping that someone might be able to
point me towards some targeted reading.

Thanks in adance,

Joseph
