Does MavProxy NTRIP work at all?

Ground Control Software MAVProxy

I’ve scoured the internet and read all the posts here on using the MavProxy NTIP module, but I just can’t seem to get it to work. I don’t see any error messages in Mavproxy (although I have no idea how to see any sort of debug messages), but when I run ntrip status I get ntrip: no data. I know I’ve set the proper caster address, port, mountpoint, username, password, and started the module like I’m supposed to.

I am running my own ZED-F9P base station with NTRIP caster using GitHub - Stefal/rtkbase: Your own GNSS base station for RTK localization with a Web GUI. I know the NTRIP caster is working perfectly because I have no problem connecting to it via Mission Planner. I’ve also tried using a few other NTRIP casters (all of which work perfectly in MP) but not a single one works.

Everything runs great in MP, but I really want to move to using MavProxy on my companion computer so I don’t have to boot up a ground station every time.

Before I start to pick apart the python source code and start to debug, does anybody have any tricks to getting it to run? Thanks!

I tried for a while but gave up.

Instead, I have the companion computer feed the F9P on a different UART using str2str from the rtklib.

I’ve checked with a local online service and appears to work fine with my HERE3 GPS:

module load ntrip
ntrip set caster ntrip.data.gnss.ga.gov.au
ntrip set port 443
ntrip set username ******
ntrip set password ********
ntrip set mountpoint GNGN00AUS0
ntrip start
ntrip status

The ntrip: no data indicates that it hasn’t been able to connect to the NTRIP caster

I just tried the same and had immediate success:

module load ntrip
ntrip set caster rtk2go.com
ntrip set port 2101
ntrip set username email@email.email
ntrip set password none
ntrip set mountpoint MOUNTPOINT
ntrip start

Replace email and mountpoint with your own info. RTK2Go accepts “none” as a valid password (does not require one for public access but does require valid email).

So I actually found the problem, and just submitted a PR for it here Adding support for NTRIP Rev1 Servers by jheising · Pull Request #1440 · ArduPilot/MAVProxy · GitHub.

I was also never able to get it to work with PointPerfect, but I think that is because PP uses SPARTN messages and not RTCM.

I was also never able to get it to work with rtgpsout.earthscope.org. Haven’t had a chance to check yet, but my guess is it’s the same reason as rtkbase.

But I definitely know now why it doesn’t work with RTKbase and it’s because of an incompatibility in MavProxy with some NTRIP servers. I wouldn’t be surprised if this is the same reason that it’s hit and miss with a lot of people.
