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, making it a companion standard to the existing OMG GEMS specification which provides a standard for the control/status-plane. By standardizing the structure of this message interface, GDDI facilitates interoperability between endpoints that agree to use compatible metadata definitions (i.e., types, identifiers/tags, etc.). GDDI is applicable to data and metadata in the digital domain, also known as baseband. This type of data and metadata includes spacecraft commands, telemetry, and mission payload prior to conversion to/from signals in the RF domain (i.e., waveform modulation). The scope of GDDI is the baseband domain. Sufficient standards already exist for the RF domain such as ANSI/VITA-49 and IEEE-ISTO DIFI.
