Q: Do GlobalTop Gmm-u1 / Gms-d1 receiver modules support all RTCM messages?

No, they do not support all RTCM messages.
There are many different types of messages available on RTCM in different versions, however the only ones GlobalTop modules based on MediaTek 3329 support are the following, which are the same for RTCM SC-104 v2.0, v2.1, v2.2, v2.3 and v3.0:

  • Type 1: Differential GPS Corrections
  • Type 2: Delta Differential GPS Corrections
  • Type 3: GPS Reference Stations Parameters
  • Type 9: GPS Partial Correction Set
