Charters : 2.04 Spacecraft Monitoring and Control Working Group

 

The ability to standardize the interfaces for spacecraft monitoring and control (SM&C) will allow significant saving in the development of the flight components and the ground segment of future space missions. In fact, it will be possible to use standardized SM&C infrastructure systems, to seamlessly transfer data across systems, and to adopt commercial-off-the-shelf applications for monitoring and control. The high level goal of this standardization effort is to make economies by:

1.) allowing interoperability with partner system and infrastructure.

2.) reducing the risk of space missions by re-using systems and operational concepts, thus increasing their reliability.

3.) facilitating the development of generic (infrastructure) on-board and on ground software that can be shared by multiple projects via simple re-configuration

4.) applying the SM&C approach and systems throughout all mission phases and to other M&C domains (e.g., ground stations, control centers, test facilities, etc.)

The goal of the working group is

GOAL 1: to pave the way for the technical work that will be performed in the context of spacecraft monitoring and control. This will be done by defining the technology-independent framework to be used in future work. It is noted that this activity involves also the space segment and therefore requires close coordination with the SOIS. This will be done by initially producing a white book and to bring it to Green status.

GOAL 2: to specify and produce the corresponding Blue/Magenta Books for the following initial set of services:

• SM&C Messaging Abstraction Layer (BB)

• SM&C Common Services (BB)

• SM&C Core Services (BB)

• SM&C Binding/Encoding MBs (former SM&C Protocol)

• SM&C Language Specific API MBs

• Update the SM&C GB to bring it in line with the changes above.

GOAL 3: to update the XTCE standard with the result of the public review together with the OMG. To update the XTCE Green Book from presentation format to actual book. To produce the XTCE Magenta Book as recommended practice on how to tailor XTCE for a CCSDS-enabled mission.

GOAL 4: to specify the other application level SM&C services identified in the Green Book.

Risk 1: Unavailability of resources to finalise started work and the relative prototypes

Mitigation: Reduce individual agencies costs by distributing work across several agencies participating to the WG. Bring issue to CMC so as to raise awareness of contributing agencies. In the worst case, descope the work.
