I would like to know if there is a way of using gpsd (together with a gpsd client) to check whether a (locar or remote) NTRIP caster is emitting corrections or not. Also, I would like to know if it is possible to access the RTCM data through the gps_data_t structure, independently of the GPS receivers connected to gpsd? In other words, is there a way of perform this without redirecting RTCM from the NTRIP Caster to the GPS receivers (*)?
Cheers,
Pablo
(*) As indicated in http://www.catb.org/gpsd/gpsd.html: "Ntrip caster. A URI with the prefix "ntrip://" followed by the name of an
Ntrip caster (Ntrip is a protocol for broadcasting differential-GPS
fixes over the net). For Ntrip services that require authentication, a
prefix of the form "username:password@" can be added before the name
of the Ntrip broadcaster. For Ntrip service, you must specify which
stream to use; the stream is given in the form "/streamname". An
example DGPSIP URI could be "dgpsip://dgpsip.example.com" and a Ntrip
URI could be
"ntrip://foo:address@hidden:80/example-stream". Corrections
from the caster will be send to each attached GPS with the capability
to accept them."
