Stack for hostile, lagging links

Our stack spans flight firmware, delay-tolerant routing, sparse RF profiles, and ground gateways — designed as one fabric, not bolted-together fragments.

HelioPulse Firmware

HelioPulse is radiation-aware flight software that monitors thermal and single-event stress, then sheds noncritical tasks before the link collapses. It exposes a small telemetry contract that Meridian Mesh can schedule around.

  • Deterministic task budgets under memory pressure
  • Watchdog policies tuned for intermittent contacts
  • Replay hooks for Twinspire digital twins

Latticewake Routing

Latticewake ranks next-hop candidates using contact plans, residual energy, and predicted occultation windows. Bundles wait when they must, sprint when a path opens, and never pretend the cosmos is a data center.

Details live in our Latticewake preprint announcement and the broader research program.

Quietband Links

Quietband is our sparse-link profile: low duty cycles, narrow scheduling envelopes, and acknowledgements that tolerate multi-orbit delay. It is the RF companion to Meridian Mesh.

Results from our latest soak test are summarized in Quietband field trial notes.
