Tutorial — Network, routing & latency

Goal: declare a connectivity mesh, find multi-hop strands, and estimate acquisition-to-delivery delay.

Steps

1. Build the mission

  1. Spacecraft or Walker constellation.
  2. One or more facilities (gateways).
  3. Optional: Coverage (Discrete is natural for latency traffic).
  4. Apply + refresh.

2. Connection Network

  1. Add a Connection Network (own plan pool).
  2. Declare edges, e.g. constellation aggregate → facility, and optional ISL edges.
  3. Set sampling step; Run Analysis.
  4. Confirm edge access windows / scene lines.

3. Routing

  1. Add Routing Study; select the network.
  2. Choose source and target endpoints (pick concrete members if aggregates).
  3. Set max hops; Run.
  4. In Reporting, open strand tables / Gantt templates.

4. Latency

  1. Add Latency Analysis.
  2. Point it at the Coverage product and the Connection Network (per editor fields).
  3. Configure payload / traffic model.
  4. Run and generate latency ReportGraph products.

Checkpoint

  • CN: non-empty edge windows
  • Routing: at least one strand (or a clear reason for none — hops / missing edges)
  • Latency: delivery statistics after Coverage + CN succeed
