Are /ublox_driver/receiver_lla and /ublox_driver/receiver_pvt the same under RTK? #17

Hi everyone,

I can capture RTK solution by using a ZED f9p but I don't know is there any difference between /ublox_driver/receiver_lla and /ublox_driver/receiver_pvt in terms of langtitude, latitude and altitude. Are they the same or /ublox_driver/receiver_lla is the original GNSS data and /ublox_driver/receiver_pvt is the corrected data by Ntrip.

Many thanks!

Hi, @yyyxs1125. They are exactly the same in terms of latitude, longitude and altitude. Both are corrected solution but /ublox_driver/receiver_pvt gives you more information like velocity and solution's type.
