Bad accuracy with NTRIP data #4

Closed BRNKR closed 2 years ago

BRNKR commented 3 years ago

Hey,

i am feeding the rtcm messages from my german ntrip provider over udp to your node. i am using "str2str" from the RTKLib. The gps position is drifting a lot.

i dont have this problem with https://github.com/ros-agriculture/ublox_f9p and https://github.com/ros-agriculture/ntrip_ros.

any idea what i am doing wrong? Is str2str not providing the correct data for you?

Thank you!

I suggest you to check the diff_soln and carr_soln flags in published GnssPVTSolnMsg. Here is the definition of this message type.

will check that out. on other drivers this info is in NavSatStatus Message included, which i observed.
