  • Display: Dual bar chart
    • Blue: In-Plane (Azimuth) deviation
    • Orange: Out-of-Plane (Elevation) deviation
  • Unit: Degrees

Timeline View

A horizontal Gantt-style visualization of every burn for the selected spacecraft, with orbital events overlaid as bands and markers to give thruster timing the right context. Route: /maneuvers/burn-plan/timeline The timeline is anchored to a UTC time axis along the top. Each spacecraft row holds the burns scheduled or executed within the current window, drawn as Gantt-style segments. Orbital events are overlaid above the burn rows as either shaded bands (entry-to-exit duration) or instantaneous markers (single-epoch events). Burn Plan Timeline

Zoom Toggle

Two zoom levels control how densely time is packed onto the horizontal axis.
ModeDescription
WideMore pixels per hour, useful for inspecting individual burns and short-duration events
CompactFewer pixels per hour, useful for scanning multi-day windows and long-arc revisit patterns
A Now button to the right of the zoom toggle scrolls the timeline to the current UTC instant.

Orbital Events

Four orbital event types overlay onto the timeline. Each renders either as a shaded band (covering an entry-to-exit interval) or as an instantaneous marker (a single-epoch crossing).
EventDisplayDescription
EclipsesBandShadow events. Distinguished into Umbra (full shadow) and Penumbra (partial shadow); each subtype renders as a band spanning entry-to-exit duration
South Atlantic Anomaly (SAA)BandGeographic region of elevated radiation; band spans entry-to-exit duration
ApsisMarkerPeriapsis and apoapsis crossings; rendered as instantaneous vertical markers
NodesMarkerAscending and descending node crossings; rendered as instantaneous vertical markers

Display Popover

Click Display in the topbar’s right-aligned controls (accessibility name Display settings) to open the Orbital events popover. Each toggle controls visibility for one event type on the timeline; flipping a toggle is reflected immediately on the visible bands and markers.
ToggleStateEffect
EclipsesOn (default)Show or hide umbra and penumbra bands
ApsisOn (default)Show or hide periapsis and apoapsis markers
NodesOn (default)Show or hide ascending and descending node markers
SAAOn (default)Show or hide South Atlantic Anomaly bands

Schedule Export Dialog

Click Export Schedule in the topbar’s right-aligned controls to open the Export Schedule dialog. The dialog generates a Spacecraft Schedule File (.ssf) listing every selected event over a chosen window. The same dialog is also accessible from the passes timeline at /passes/timeline. Export Schedule dialog

Spacecraft

A single-select dropdown listing every spacecraft in your tenant. The dialog defaults to the spacecraft already selected on the timeline.

Date Range

ElementDescription
Start DateCalendar picker; selectable range covers 7 days before today through 7 days after today
End DateCalendar picker; cannot be earlier than Start Date and cannot exceed 7 days after Start Date
Time inputsHH:MM format, UTC for both Start and End
Maximum window7 days

Include

Five checkboxes determine what the exported .ssf file contains. All five are checked by default. With every checkbox unchecked the Download button is disabled and the dialog displays the validation message Select at least one event type.
CheckboxStateWhat it includes
EclipsesChecked (default)Umbra and penumbra entry/exit events
ApsisChecked (default)Periapsis and apoapsis crossings
NodesChecked (default)Ascending and descending node crossings
Ground Station PassesChecked (default)Visibility windows for selected ground stations
South Atlantic Anomaly (SAA)Checked (default)SAA entry/exit events

Ground Stations

The Ground Stations card appears only when Ground Station Passes is checked. Use it to restrict the exported passes to specific ground stations.
  • Click the trigger button to open the picker.
  • Check the stations to include; leave the selection empty to include all configured stations.
  • The trigger label reads All ground stations when no stations are selected, or N selected when one or more are picked.
The card’s helper text reads Select specific ground stations or leave empty to include all.

Key Concepts

What is a Burn Plan?

A burn plan (maneuver) represents a planned or executed thruster firing to change a spacecraft’s orbit. Key parameters include:
  • Delta-V: Velocity change in m/s
  • Delta-Mass: Propellant consumed
  • Duration: Burn length in seconds
  • Reference Frame: Coordinate system (RTN or TNW)

Maneuver Lifecycle

  1. PLANNED: Maneuver is scheduled but not yet executed
  2. TELEMETRY: Execution reported with actual timing data
  3. Performance Analysis: Compare actual vs planned after execution

Performance Metrics

  • Magnitude (Efficiency): Actual delta-V vs planned delta-V (100% = perfect)
  • Pointing: Angular deviation from planned direction (0 degrees = perfect)
