GDRT (GFZ Displacement Real-Time) is the data format of the Real-time Precise
|
|
|
|
|
|
Point Positioning (RTPPP) provided by the Helmholtz Centre Potsdam – GFZ German
|
|
|
|
|
|
Research Centre for Geosciences. This development was supported by the German
|
|
|
|
|
|
Federal Ministry of Education and Research (BMBF) within the EWRICA project.

The GDRT plugin is a SeedLink plugin that converts GDRT UDP messages to
|
|
|
|
|
|
miniSEED channels according to the following table:
