can't get RTK on rover

[marcusbarnet]

I correctly installed the package and I launch it with: roslaunch ublox_gps ublox_zed-f9p.launch as described in the readme.
The problem is that my C099-F9P rover board never enters in RTK mode.
I can get the RTK mode if I connect it to windows while running u-center.

Is there any option I need to add in the config file?

thank you!

Moreover: I noticed that as soon as I shutdown the ROS node, the module enters in RTK mode.

I'm using the zed-f9p.yaml file.

# Configuration Settings for ZED-F9P device

Hi Jeong, Thanks for your reply. The main issue I think is getting the corrections through the server. I connect but do not receive anything. I found out today that is necessary to send NMEA messages in order to get corrections (at least here in Croatia). However, I do not know how to do that yet. I guess the same ntrip client node has to deal with that, right? Can I ask you about the order you run it? I mean, do you launch first the ublox zed-f9p node and later the ntrip node to get corrections? Thanks and regards, PhD Eugenio Alcalá

Hi Eugenio

You should fill in 'URL, PORT, USER_ID, USER_PASSWORD, MOUNTPOINT' information
in here :
https://github.com/ros-agriculture/ntrip_ros/blob/master/launch/ntrip_ros.launch

I obtained this information from a government department related to geographic information in Korea, but you can use services from your country or free services.

I hope this is helpful to you.
