Mission template — Walker constellation & IoT-style coverage

Tutorial · Mission template

Goal: generate a small Walker constellation from a seed LEO satellite, cover an AOI with Discrete demand events (IoT / messaging style), and read event-capture KPIs.

Mission card

Field Suggested value
Mission name Walker-IoT-Coverage
Scenario 12–24 h, step 30–60 s
Seed spacecraft SEED-1 — LEO ~550–600 km, inc ~53° or SSO
Constellation Walker Delta, N=4, P=2, F=1, prefix IOT
AOI Regional box or country
Coverage Discrete — random_n_in_aoi, N=50, seed=100
Acquirer Constellation aggregate (or all members)

Step-by-step

1. Seed and Walker

  1. Create mission; add SEED-1 with a LEO orbit you like.
  2. Apply.
  3. Create Walker Constellation from the seed: Delta, N=4, P=2, F=1.
  4. Apply — confirm four members under the constellation.
  5. Refresh scene.

Tip

Stay inside plan caps (maxConstellationSatellites). Start tiny; scale N only when the workflow works.

2. AOI and Discrete coverage

  1. Add AOI over the service region.
  2. Add Coverage Analysis.
  3. Type Discrete; demand mode random_n_in_aoi; N=50; note the seed.
  4. Acquirers = constellation aggregate.
  5. Run.

3. Interpret and iterate

Knobs Effect
Change demand seed Different random draw — not a full Monte-Carlo by itself
Increase N events Richer statistics (plan caps apply)
Switch to Continuous Area metrics instead of event capture
Add facilities + CN Path toward Latency delivery

4. Optional Latency chain

  1. Build a Connection Network constellation → facilities.
  2. Run CN, then Latency pointed at this Discrete coverage.
  3. See Network → Routing → Latency.

Checkpoint

Discrete coverage completes; event-oriented ReportGraph templates available; constellation members visible in the scene.
