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.
Nadirlink Gateways
Nadirlink is the ground-side edge: operators ingest Meridian bundles, inspect Twinspire rehearsal logs, and hand off clean telemetry streams to mission control tools.
