RELEASE 4.12 — ANOMALY-AWARE TASKING — LIVE

The operations layer for your satellite constellation.

Helion is the platform commercial operators use to task satellites, stream telemetry, plan downlinks, and respond to anomalies in seconds — not hours. One API. One dashboard. Twenty-four constellations already in production.

What Helion does, plainly

We sit between your spacecraft bus and your mission team. We translate vendor telemetry into a consistent model, schedule contacts, queue tasking, and escalate when something looks wrong.

PILLAR 01

One API, every bus

A normalised telemetry and tasking API across all major commercial buses. No more per-vendor integrations, no more per-mission ground software stacks.

PILLAR 02

Anomaly response, automated

Watchdog rules trigger tasking changes, operator alerts, and ground-station handoffs in seconds. The on-call rota can sleep through the night.

PILLAR 03

Audit-grade by default

Every command, every downlink, every operator action is recorded, signed, and replayable. We get the regulator's questions. You do not.

TELEMETRY

One model for every bus on orbit.

Helion normalises vendor-specific CCSDS, Iridium, and proprietary frames into a single state model. Query it with the same GraphQL whether you're flying a 6U cubesat or a 400-kg EO bird.

  • Plug-in decoders for SpaceX, York, AAC Clyde, Planet, Kongsberg
  • Sub-second stream-to-API with backpressure handling
  • Replay any contact, with original raw frames retained

TASKING

Plan, prioritise, and re-plan without phone calls.

Operators see a single queue of opportunities ranked by mission value, fuel budget, and downlink window. Conflicts resolve themselves, or escalate to a human with full context attached.

  • Drag-and-drop re-tasking, with diff and roll-back
  • Time-to-acquisition under 90 seconds for LEO
  • External mission clients can submit requests via the same API

ANOMALY

Catch it at 03:00, not at the morning briefing.

Helion's anomaly engine runs on every contact, on every satellite. It detects deviations from the operator-defined safe envelope and triggers a configurable response chain — task a reset, page a person, or open a Jira ticket.

  • Per-spacecraft safe envelopes with rate-of-change bounds
  • Vector clocks for ground-station failover
  • Full incident timeline with original telemetry, attached to a single URL

Release
4.12.2May 18, 2026

Anomaly-aware tasking is generally available

The biggest release of the year. Watchdog rules can now chain into automated re-tasking, with full audit trail and human-in-the-loop escape hatches.
Post-mortem
EngineeringMay 11, 2026

The 4.11 ground-station incident, in full

Twelve minutes of degraded telemetry on the Svalbard uplink, what we missed in staging, and the three things we changed so it doesn't happen again.

Q1 customer letter: contacts, latency, and roadmap

What we shipped, what slipped, and the three things we are committing to before the end of Q2. Honest numbers, no marketing.

What our customers say

We replaced four ground software stacks with Helion and our on-call rota sleeps through the night for the first time in three years.
— VP Operations, EO constellation operator
The audit log alone is worth the contract. We can answer a regulator's question in an afternoon instead of a quarter.
— Compliance lead, sovereign EO customer
Helion is the only vendor in this category that took the time to understand what a real operations team actually needs.
— Mission Director, IoT constellation

Stop running your own ground software.

Helion replaces four-to-eight vendor integrations with a single platform. 30-day pilot for qualified operators. No charge for the first constellation under evaluation.
