Take a look, you will need carrier phase messages to get cm. TYPE 18 and 20 - are RTK uncorrected carrier phase data and carrier phase corrections. Type 19 and 21 - are the uncorrected pseudo-range measurements and pseudo-range corrections used in RTK. As I have just one LEA-4T receiver I have note tested RTK or post-processed Kinematic, yet, but I will do it. I have reached 1 cm static with LEA-4T, 10 Km line lenght. I have made an aluminum plate ground plane for my antena to try to cut off some multipath. good luck, julio menezes _______________________________________________ This message is sent to you from [email protected] mailing list.
