3DM-GQ7 RTCM / NMEA configuration for external data
Closed this issue · 2 comments
I want to use an external ntrip server for the rtcm data. Previously I used another GNSS receiver with your ntrip_client to get the rtcm_msgs via the nmea_msgs message.
If I read the documentation correctly, one way to get the rtcm data to the 3DM-GQ7 is to use the aux port via a second cable. Is this correct?
If so, how do I configure the 3DM-GQ7 in the yaml to receive the nema message via ROS and how do I configure the ntrip_client node to send the rtcm data to the 3DM-GQ7 via the aux port, or does the microstrain_inertial_driver send the rtcm data to the 3DM-GQ7?
Expected behavior
Getting rtcm data on the 3DM-GQ7
Environment (please complete the following information):
- OS: Ubuntu
- Architecture: x86_64
- ROS Version: humble
- Version: 4.3.0
- Sensor(s): 3DM-GQ7
If you set the ROS param ntrip_interface_enable: True
then it will subscribe to RTCM messages that the ntrip_client publishes, and write them to the aux port, as well as read NMEA sentences from the aux port and publish them for the ntrip_client.
Thanks for answering this @Aposhian. I am closing this issue.
Additionally, for a simple example of using microstrain_inertial_driver
with the ntrip_client
, check out microstrain_inertial_localization
and it's wiki page, specifically the NTRIP Settings section
