One evidence core across spacecraft, ground stations, space insurance and ground-motion data. Every finding is cited to its source or withheld. Jantar proposes; a human authorises.

ARCHITECTURE

The Tri-Plane Architecture

Data, reasoning and command are kept apart, modelled on the zero-trust architecture of NIST SP 800-207. Reasoning reads data through one audited interface, and nothing it writes can reach a transmitter.

Three stacked layers of a knowledge graph: glowing nodes joined by thin lines, one node highlighted

WHO IT IS FOR

Four Readers, One Rule

Four questions, one answer format: cited or withheld. This is who Jantar is built for, not a list of customers.

JANTAR OPS

Satellite Operators & Constellations

A cited root cause and a drafted recovery procedure for each anomaly, grounded in the spacecraft's own documents.

Flight Ops Architecture
JANTAR RISK

Space Insurance Syndicates

A sealed, cited record of what the spacecraft did over the policy period. The carrier decides; Jantar prices and settles nothing.

The Evidence Specification
JANTAR GROUND

Ground Stations & Teleports

Every pass scored against its link budget, and a verdict on whether a fault is on the ground or in orbit.

Ground Segment Specs
JANTAR EARTH

Infrastructure Ground Motion (publication gated)

Cited, quality-flagged ground displacement from published radar interferograms. Built; not yet served to customers. No failure-time prediction.

SPACE TO GROUND

Onboard AI Detects. The Ground Explains.

More satellites now carry their own AI computer. Jantar is the ground-side check on what it reports: each onboard detection is investigated against the spacecraft's own documents, and is never taken as evidence by itself.

A satellite carrying its own computer sends an alert down to a ground station; the alert passes through a stack of evidence layers to a check, and a person at a console decides
In orbit · partner hardwareOnboard ComputerA detector on the operator’s own computer flags a deviation.
DownlinkAlert and TelemetryThe alert arrives with the telemetry around it.
On the groundJantar InvestigatesAgainst the spacecraft’s own documents: corroborated with a citation, or flagged as a possible false positive.
AuthorityA Human DecidesJantar proposes a procedure. A person authorises it.
BUILTAn onboard detection opens a ground investigation, on a partner’s own craft once it is onboarded. The report says whether the evidence corroborates it, and whether the model that raised it is one registered for that craft.
BUILTThe onboard computer is investigated as a unit of its own: throttling, resets, memory errors and model output drift, each against its own documents.
BUILTA reference onboard detector, and a Rust port held byte-exact to it by shared test vectors.
ROADMAPAn ARM build of the reference detector and a model export contract, so a partner can run it on their own computer.
Onboard detections are read today from CCSDS PUS event reports and from seeded replay; no live onboard feed is connected. A partner's own craft and models can be brought in through the API; no partner has done so, and the console has no form for it. The onboard computer investigated today, and the only registered onboard model, are synthetic and belong to the reference spacecraft; no real module's figures are used. The detector is a reference implementation, not flight software. Jantar builds no flight hardware and commands nothing.

THE EVIDENCE GATE

Grounded, or Withheld

Jantar releases a root cause only when the spacecraft's own knowledge graph backs it. When the grounding is absent, it declines.

Two lanes through the same gate: with documents and a knowledge graph beside it the gate opens onto a check mark; with those missing the gate is barred and the result is an empty outline
A · Evidence present
Seeded FaultA known fault on the reference spacecraft.
Evidence GateIs the cause documented, and is every claim cited?
ReleasedThe cause, with its citations.
1.000Root cause top-1 (grounding present)
1.000No unsafe release
B · Evidence removed
Same FaultThe identical anomaly, with its documentation taken out.
Evidence GateNothing documents the cause any more.
WithheldDeclined, or a different documented cause. Never an undocumented one.
1.000Grounded honesty under ablation
1.000Citation integrity under ablation

SECURITY & COMPLIANCE POSTURE

Built to Run Inside Your Boundary

Designed to run hosted or fully air-gapped. The posture below is self-attested and has not been independently audited.

Two deployments side by side: an open platform of servers linked out to a globe, and the same servers sealed inside a glass enclosure that an outside line cannot enter
HOSTED

Hosted Deployment

  • GKE, Cloud Storage and BigQuery run in Mumbai (asia-south1).
  • A hosted model may process a prompt in any Google Cloud region.
  • The DPA lists every sub-processor.
AIR-GAPPED · YOUR ENCLAVE

Air-Gapped Deployment

  • Runs fully offline, with a local deterministic model.
  • Spacecraft telemetry does not leave your enclave.
  • Every network source is refused.
POLICY ALIGNEDDesigned against the Indian Space Policy 2023 and IN-SPACe guidelines. Which guidelines apply to each product line is a question for counsel.
SELF-ATTESTEDDesigned to align with India’s Digital Personal Data Protection Act 2023. No certification is claimed.
HASH-CHAINED RECORDOperator decisions are appended to a per-tenant hash chain, so an edited entry breaks the chain.

One source per deployment, or several bound to each craft. Every adapter reads and none writes; one that needs a network is refused in airgap mode. The MQTT, Kafka and AWS Ground Station adapters are tested against simulated brokers and recorded data only, not yet a live feed.
