International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The Space Station Verification and Training Facility is using an object-oriented
design methodology for software design, a rate monotonic scheduling and message
passing system to support the highly distributed environment, and the Ada language to
implement most of the software. One of the subsystems within the Space Station and
Training Facility is the Space Network Simulator. Space Network simulators are used
to provide training of ground controllers and flight crews, providing a model of
real-world formats and protocols. This gives the controller the appearance of a
real-world network, providing valuable training. To develop a simulation of the space
network within this distributed environment, software objects are under development
to dynamically simulate the existence of the space vehicle(s) and their communication
components. Communication components include the on-board antennas,
transponders, communication systems, and corresponding communication ground
control facilities. Telemetry systems are used in the simulation to provide the control
of actual data manipulation, as a function of the state of the simulated Space Network.
The telemetry system automatically formats appropriate telemetry characteristics
through mode and control commands. A software model is under development to
provide a transparent interface between the software objects and the telemetry system,
allowing the objects to execute without knowledge of the particular telemetry system
in use. A transparent interface between the software and hardware, within this
object-oriented methodology, reduces the propagation of change to software models as
the interface requirements change.
