EX13 — Observation To Delivery¶

Tags: observation · finite slew · store-and-forward · power Input: observation-to-delivery.yaml · Runtime tier: standard · Recommended views: 3D, Attitude, Power, Analysis

Purpose¶

Trace data from regional collection opportunity through achievable pointing, onboard activity, store-and-forward transport, ground delivery, and spacecraft power.

Setup¶

Six satellites observe three targets and downlink through three ground sites over 12 hours at a two-minute cadence.

astraeus run astraeus-resources/examples/user/observation-to-delivery.yaml

RunSpec Focus¶

Several requested stages form one evidence chain. Store-and-forward is enabled so captured products may wait for a later gateway opportunity.

Results¶

The reference run completed successfully in 2.15 seconds. The observation stage created 180 MB across three targets; transport delivered 164 MB (91.11%), with 16 MB remaining at the end of the run. Fleet state of charge stayed between 68.92% and 74.62%, with no power infeasibility.

Captured data separated into delivered products and end-of-run backlog

Artifacts To Inspect¶

Artifact	What it shows
`mission/observation_summary.json`	Target count, capture duration, and total product volume
`mission/observation_capture_events.parquet`	Time, spacecraft, target, and product for each capture
`transport/transport_delivery_events.parquet`	Product delivery, partial delivery, and expiration events
`transport/transport_backlog_timeline.parquet`	Undelivered product volume and age through the run
`power/timeline_power.parquet`	Electrical response to capture, processing, and downlink activity

Interpretation¶

Collection success and delivery success are separate outcomes. The residual 16 MB shows that a product can be captured yet miss a suitable delivery opportunity within the study horizon. Extend the horizon or alter gateway geometry before interpreting residual backlog as lost data.
