NOTE As a lesson learned from many project experiences, this aims at making sure that deviations on a given mis

34、sion are driven by mission requirements and are tracked at specification time rather than being discovered at integration time which results in delays and generally induce large costs impacts. Enabling the development of spacecraft onboard communication services compatible with the CCSDS/SOIS requir

35、ements. As far as possible, the defined communication requirements are extracted from the experience on existing spacecraft specifications. 4.3 Reference architecture 4.3.1 Communication devices architecture There are three types of communication devices in MIL-STD-1553B data bus systems: Bus Contro

36、llers (BC), Remote Terminals (RT) and Bus Monitors (BM). BM devices are not subject for any additional requirements within this standard but their usage for integration and test is recommended. The Figure 4-1 depicts the reference architecture of typical BC and RT type communication devices with 155

37、3 I/F. Only OSI protocol stack related elements of the communication devices are shown in this view. This can entail units with an existing 1553 I/F design (legacy units), as well as enhanced 1553 communication devices. These units can involve usage of different services, which can be supported by s

38、pecific driver software. The communication devices exchange their data through a time-multiplexed wire-harness medium, which topology is further detailed in clause 4.3.4. 4.3.2 Mapping on CCSDS/SOIS sub-network layer This Standard provides the definition of a set of services that can be mapped on th

39、e Sub-network layer of the CCSDS/Spacecraft Onboard Interface Services communication stack as described in Figure 4-2. The services, as defined in this standard, are directly compatible to the Packet Service, Memory Access Service, Time Distribution Service, Device Discovery Service and Test Service

40、 of the SOIS reference model. For some of these services, additional SOIS-specific control information can be needed. The definition of this control information, as well as the capabilities and requirements of the Data Link Convergence Functions, is outside the scope of this standard. EN 16603-50-13

42、ervices in this standard. Figure 4-3 depicts this general service model. Management entity Capability Service User Underlying Layer Service Interface Expected Service Service Management Interface Figure 4-3: Service model The services defined in this standard describe communication capabilities of s

43、ervice-provider which is provided to service-user at the boundary between service-provider and service-user This capability in its turn relies on certain services expected to be provided by the underlying layer. The interactions between the service-user and service provider constitute “abstract inte

44、rface” at the service boundary. This abstract interface is defined in terms of service primitives which the service-user and the service-provider are allowed to exchange, together with sequencing rules which apply to these exchanges. The UML sequence diagram convention is used throughout this standa

45、rd to illustrate how sequences of interactions are related in time. The OSI convention and terminology is used to represent service-primitives on those UML sequence diagrams. Services are configured and managed by a service management entity. Service primitives are described through their name (e.g.

46、 SendData, ReadStatus), type (e.g. Submit, Deliver or Requestor.Submit, Acceptor.Deliver) and list of parameters (e.g. GroupID, DataLength) Service primitive is represented by an arrow. Arrows located at the left of the vertical line indicate requestor primitives Arrows located at the right of the v

47、ertical line indicate acceptor primitives Arrows directed towards the vertical line indicate submit primitives Arrows directed out of the vertical line indicate deliver primitives Primitives are an abstract, atomic representation of an interaction between service-user and service-provider which are

48、defined in clause 7 of this standard. The primitives and their parameters indicate what information flows between the service-user and the service-provider at their interface. This is not to be confused with an API which is associated with a specific implementation. EN 16603-50-13:2014BS EN 16603-50

49、-13:2014There are three types of parameters associated with each definition of a service primitive Input, Output, and Managed. The CCSDS Draft Recommendation for the encapsulation service CCSDS-133.1-R-1, Red Book, April 2002, provides the following definition for managed parameters: “In order to conserve bandwidth on the space link, some parameters associated with a Service are handled by management, rather than by inline communications protocol. The managed parameters are those which tend to be static for long periods of time, and whose change generally signifie
