Rtcm messages

There are two sets of RTCM RTK message types (18/19 and 20/21), which are intended to be used as pairs. However, there is no requirement in the RTCM SC-104 standard that they be used together. A type 18 (raw carrier phase) message couldbe paired with a type 21(RTK pseudorange correction) message, or even a type 1(pseudorange correction) message.Jun 05, 2022 · Good morning to all members of the community. My concern is simple: is it possible to log messages RTCM in SURVCE (V6.x) for further processing? In GPS Utilities there is a tab from which a command file can be uploaded and sent to the receiver.
