Is your feature request related to a problem? Please describe.
Hi, I would like to ask if there is any possible to enble this function, because I need the SPARTN msg to correct my GNSS. Convention method is the RTCM but I could not use this, can you add this function?
I used Ublox-NEO-D9S and Ublox-ZED-F9P and rely only on L-Band. But I did not find any support for this in the ROS system.
Here is the introduction of pointperfect: https://developer.thingstream.io/guides/location-services/pointperfect-getting-started

Describe the solution you'd like
Add this function in the ROS driver.
