OrbitScope Help

OrbitScope is an interactive satellite operations viewer. It combines a rotatable 3D Earth, live orbital propagation, constellation filters, ground-station overlays, visibility footprints, and alert hooks in a single browser surface.

Main use Inspect live satellites
Best interaction Search, rotate, filter, zoom
Operational views Footprints, contacts, tracks
Data mode Live cache + local fallback
Core workflows

Select a satellite, inspect its orbit, view its approximate visibility footprint, compare families, and watch live motion against Earth and ground infrastructure.

Operators, analysts, demos

Useful for live demonstrations, quick constellation review, training, and operational intuition around altitude bands, tracks, and contact geometry.

How to use the globe

Navigate Rotate and zoom

Drag to rotate the Earth. Use mouse wheel or the zoom buttons to change viewing distance.

Focus Select a satellite

Search by name or click a satellite to highlight it and reveal orbit, footprint, and future track details.

Reset Return to default view

Use Reset View to restore the default orientation and zoom level.

What each panel does

Right control panel
  • Search all loaded satellites by name.
  • Filter by constellation family and orbit band.
  • Read altitude, orbital radius, inclination, and period.
  • Adjust simulation speed and jump forward or backward in time.
  • Show or hide ground stations and coverage cones.
  • Filter ground stations by network.
  • Refresh the live server-side satellite cache.
Lower detail panel
  • Shows selected satellite metadata and live position.
  • Displays current ground track and future path points.
  • Lists next predicted station contacts.
  • Provides alert configuration for visibility or altitude thresholds.

What the map is showing

Satellites Family color coding

Families are color coded, for example Starlink in red, GPS in purple, weather systems in green, and stations in yellow.

Projection Approximate visibility footprint

When selected, a satellite shows a blinking Earth footprint based on geometric visibility with a fixed elevation mask.

Ground layer Stations and cones

Ground stations are drawn on Earth and their coverage geometry can be displayed for situational context.

What are names like White Sands, South Point, Guam, or Kourou?

Those are ground stations on Earth, not satellites. OrbitScope uses them as fixed Earth sites for communications, tracking, contact geometry, and station-visibility alerts. The named point is the station location, and the surrounding colored geometry shows approximate visibility or coverage context.

What can be analyzed quickly

Constellation and orbit summaries
  • LEO, MEO, GEO, and HEO counts
  • Dominant family and family mix
  • Median altitude of the filtered set
  • Visible-on-screen count for the current view
Operational interpretation
  • Identify dense orbital shells
  • Compare coverage patterns by family
  • Inspect how altitude affects footprint size
  • Review likely ground visibility windows

Alert modes

Mode 1 Station visibility

Arm an alert when the selected satellite becomes visible to any enabled station or a chosen station.

Mode 2 Altitude below threshold

Arm an alert when the selected satellite drops below a configured altitude value.

Output Browser notification hook

If browser permission is granted, OrbitScope can raise a local notification when the alert condition is met.

Interpretation and limits

  • Satellite positions are propagated from loaded orbital elements and rendered continuously in the browser.
  • Selected satellite footprints are approximate visibility footprints, not payload-specific RF coverage maps.
  • Ground-station contact logic uses a fixed elevation mask rather than a per-network antenna model.
  • If live remote refresh is unavailable, OrbitScope falls back to cached or bundled data so the app remains usable.
