GDDI — Ground Data Delivery Interface
The Ground Data Delivery Interface (GDDI) specification defines a lightweight message interface standard to encapsulate spacecraft data and metadata for transfer between ground applications within a common network using a model-driven approach. The purpose of GDDI is to standardize the data/bearer-plane for digital baseband data within satellite ground systems, facilitating interoperability between endpoints that agree to use compatible metadata definitions.
