Mission Operations Services: Concept

Interfaces: Point to Point, Data Flow Oriented, Full Protocol Stack Services: Many to Many, Information Oriented, One Layer of Stack

Service Objects: represent Domain Specific Information Event Messages synchronise the Consumer’s View Control Messages allow the Consumer to invoke Operations

Each MO Service has its own specialised Information Model Generic Common Service: publish Events and invoke Operations

X3DMON Overview

X3DMON (X3D MONitoring tool) was developed as the LogicaCMG contribution to the BNSC sponsored SM&C prototyping activity.

X3DMON is a diagnostic tool that can be used by operators to view parameter updates visually on a 3D spacecraft model. It relies on CCSDS SM&C services for the delivery of parameter data. It is written entirely in Java.

X3D is a emerging open XML based standard for 3D models, which aims to promote interoperability. It is widely expected to supersede VRML (Virtual Reality Modelling Language) in the near future.

The Xj3D API has been used to provide 3D capabilities. Xj3D is a project of the Web3D Consortium focussed on creating a toolkit for X3D content written in Java. The Xj3D API has been developing rapidly and release 1.0 was made on 17th April 2006.

Xj3D is an open source product licensed mostly under LGPL. A key development for 3D applications running on the linux platform has

been the move from XFree86 to X.org for the X-windowing implementation. This has allowed hardware 3D acceleration to be utilised by applications and makes a dramatic difference to performance.

A particularly useful feature of X3DMON is the ability to associate parameters with views of the 3D model.
