hiflyViews motivation ESA side
hiflyViews motivation ESA side

• Most EGOS subsystems deal with telemetry (TM) in
  one form or another
• In fact, several EGOS subsystems display
  telemetry, often in graphical form
• NCTRS
• Web remote monitoring system (Web-RM)
• Monitoring and control (SCOS-2000)
• Satellite simulation (SIMSAT)
• But each of these implements its own telemetry
  visualization component!
• The way to go a single EGOS-broad generic
  telemetry visualization component

hiflyViews motivation commercial side
hiflyViews motivation commercial side

• Commercial satellite operators world-wide were
  contacted seeking ways to improve operations via
  enhancements to the way in which telemetry is
  visualized
• It was realised that commercial operators have
  specific telemetry visualization needs, in
  particular on
• Performance graph over one day worth of
  telemetry ready in a few seconds
• Flexibility at all levels for displays
  (zooming, panning, ...), configuration
  (on-the-fly configuration for all items), TM
  acquisition (go backwards until there is an OOL,
  ...)

hiflyViews scope
hiflyViews scope

• With this motivation, GMV undertook a cofinanced
  GSTP with ESOC entitled Lightweight graphical
  visualization of TM parameters data
  (S2KDisplays)
• The project has gathered a complete set of
  requirements coming from commercial and
  institutional spacecraft operators
• The design covers all the requirements
• A (major) subset of the requirements are being
  implemented
• The software is being integrated into hifly, our
  complete solution for satellite fleet operations
  based on SCOS-2000, under the name hiflyViews

What is meant by generic telemetry visualization?
What is meant by generic TM visualization?

• Deal with generic telemetry the word telemetry
  means remote measurements, in any context such
  as
• One satellite / satellite fleets
• Telecommunications / scientific missions
• Space / ground segment
• ... but also stock exchange rates!
• Deploy formalised interfaces for
• Telemetry acquisition
• Display definition
• Consider a flexible architecture and
  visualization framework which can easily be
  extended

hiflyViews generic telemetry
hiflyViews generic telemetry

• hiflyViews deals with parameters
• Each parameter is identified by a mnemonic and
  source ID (satellite within a fleet, on-board
  subsystem, TM stream, ground equipment, ...)
• Each parameter has one (the source one) or more
  representations (values raw, engineering,
  statistical, ...)
• Each representation has zero or more be-haviours
  (allowed limit, delta limit, ...), units,
  validity (whether it can be trusted) and error

8
hiflyViews formalised interfaces telemetry
acquisition
Formalised interfaces telemetry acquisition

• TM acquisition has been fully formalised as a
  CORBA ICD being incorporated into the TM chain
  refurbishment initiative for SCOS-2000
• Advanced TM acquisition concepts
• Start/end condition start from a time or when
  the parameter values, rate of change, validities
  or behaviours attain certain conditions (equal,
  less than, ...) finish at a time or when the
  start condition becomes false
• Sampling all samples, only the first within an
  interval, or only those attaining certain
  conditions go forward or backwards in time
• Notification notify samples one by one or in
  groups, all or on change, via push or pop

9
hiflyViews formalised interfaces display
definition
Formalised interfaces display definition

• Displays defined in XML via XML Schema
• Displays made of freely arranged cells
• Each cell contains one layout, used to lay out
  properties (see below) in a certain way
• Alphanumeric, graph and synoptic layouts are
  initially supported, but more can easily be added
• Synoptic layouts support lines, circles, ... as
  well as embedded layouts or displays

10
hiflyViews model and visualization framework
Model and visualization framework

• hiflyViews exploits the model-view-controller
  paradigm
• The controller is the set of TM acquisitions
• The model is the set of parameters,
  repre-sentations, behaviours, layouts and
  displays
• The views are the actual visible items
• Many model items have state, which convey a
  validity and a behavioural state
• A display can be flagged as OOL if it contains
  one or more OOL telemetry parameter ...
• Any view item may depend on any property of any
  model item
• A display could render the status of other
  displays valid in white, invalid in red ...

hiflyViews features overall
hiflyViews features overall

• Workspace concept save/load your setup
• Navigation through time and displays

• Layered configurability up to three levels
  (global, per-display and individual)

12
hiflyViews features displays
hiflyViews features displays

• Notes associated to parameters and displays
• Rich text fonts, colours and styles
• Sizing resize and scale (with size to fit
  feature), zoom and pan
• Layers can be individually hidden
• Export to textual and graphical formats
• Drag and drop
• Copy and paste
• Specific rendering depending on validity or
  behavioural state
• An invalid sample in a GRD can be either not
  plotted, plotted in invalid colour, or plotted
  with an additional glyph (such as a cross)

13
hiflyViews features layouts
hiflyViews features layouts

• Alphanumeric
• Add/delete rows and columns
• Resize columns
• Sort rows
• Graphs
• Auto-scale
• Line smoothing
• High/low limits drawn as lines
• Guide line
• Stack/unstack multiple graphs
• State labels for multistate parameters
• Two cursors for getting ?x, ?y and slope
• Synoptic
• Images
• Connections for electronic diagrams

Conclusions
Conclusions

• hiflyViews is a flexible and generic telemetry
  visualization tool
• hiflyViews provides
• Generic TM handling
• Formalised access to telemetry (CORBA) and
  display definition (XML)
• A flexible model and visualization framework
  which can easily be extended
• ... so it can be integrated with any control
  system
