[CSS-CLOUD] OMG Ground Data Delivery Interface

[Biggerstaff, Craig (JSC-CD42)[KBR Wyle Services, LLC]]

Dear all,

The blurb below at the OMG Space Domain Task Force<https://www.omg.org/space/> website reads as if OMG also is pursuing work similar to CDDS'.  There is a 37-page PDF available at the link below describing their request.  Thought I would bring it to your attention in case you were not aware of it:

Ground Data Delivery Interface (GDDI) RFP<https://www.omg.org/cgi-bin/doc.cgi?space/2023-3-1>: Space vehicle operations require varying compositions of ground applications that are integrated together within a common network (WAN and/or LAN) to provide an end-to-end ground system capability. This includes real time data and metadata transfer across these applications. Typical data includes spacecraft bus commands, telemetry, and mission payload in digital/baseband form. Metadata is carried in-band with the data and includes parameterized information and real-time status used by the ground applications to properly process, store, retrieve, and deliver the data. No common model for this dynamic data/metadata interface currently exists. Approaches, designs, and custom protocols vary widely from one vendor to another offering little opportunity for reuse to system integrators. The result is often a costly and time-consuming integration effort. This RFP solicits proposals for the following: 1) A Platform-Independent Model describing a lightweight application-level message interface that encapsulates spacecraft data and metadata so they can be transferred between ground applications within a common network. 2) At least one Platform-Specific Model describing the encoding format of the metadata and data encapsulated by this interface. This platform specific model will call out at least one standard transport layer for carrying the encapsulated/encoded metadata and data, with the intent of reusing an existing transport that provides high throughput, low latency, and optionally secure transmission.

I don't have any further information about OMG's activity; just stumbled across it today.

Best regards,



Craig
