Glossary
Reference for the NAVIS Orbital Interface — concepts, the decision model, and the full satellite catalog.
Every satellite in orbit
Browse the full public catalog — thousands of active objects sourced from CelesTrak — in one table with deep filters and sorting by orbit, altitude, inclination, period, and launch year.
6-Layer Decision Engine
Every satellite passes through six sequential layers — each consuming the layer before it and adding evidence to the final, citation-backed decision.
- 1. Compliance — mission-life & disposal-deadline checks
- 2. Risk — 0–12 scoring: compliance, modelled collision probability, operator-supplied health data
- 3. Forecast — disposal success probability
- 4. Economics — expected-loss & Monte Carlo exposure
- 5. Decision — one of four canonical outcomes
- 6. Governance — decision records & audience reports
Economic Model
How NAVIS prices risk: expected collision loss (asset value × collision probability), disposal-failure exposure, and a Monte Carlo loss distribution reported as P10 / P50 / P90.
API & Integration Docs
REST API for fleet, metrics & conjunction screening. Enterprise.
Using the NAVIS Dashboard
The dashboard summarises fleet health and the latest decisions. Drill into any satellite for its score breakdown and disposal window, then open Compliance to review reference thresholds and export audience reports.
Step-by-Step Onboarding
Set up your org
Create or join an organization — your fleet, members, and billing all scope to it.
Track satellites
Add public objects by NORAD ID or upload private assets; TLEs are fetched automatically and refreshed daily.
Review compliance rules
Review the reference regulatory thresholds the engine's findings are compared against.
Review & export
Read each satellite's decision, then export regulator, insurer, and operator reports.
Glossary of Orbital Terms
DECISION
One of four canonical outputs the engine emits per satellite: CONTINUE, ESCALATE_REVIEW, PREPARE_DISPOSAL, or INITIATE_DISPOSAL — each backed by a citation chain.
RISK SCORE
Aggregate score on a 0–12 rubric: compliance status, modelled collision probability, operator-supplied health data (fuel, battery) when available, and an end-of-life readiness adjustment of up to +2. Higher means more urgent action is warranted.
SCORE BREAKDOWN
The per-factor contributions — Compliance, Collision Risk, Fuel Reserve, Battery Health, EoL Readiness — that sum to the risk score, each shown with its reason and cited source.
CONFIDENCE
Forecasted probability (0–1) that the recommended path succeeds, refined by operator-supplied health data (battery, fuel) when available.
DISPOSAL WINDOW
Estimated days remaining before the post-mission disposal deadline (planned life minus mission day), paired with an urgency flag (LOW / MODERATE / HIGH).
EOL READINESS
End-of-life readiness score (0–100) and tier — OPTIMAL, STABLE, MARGINAL, or AT RISK — indicating how prepared a satellite is for safe disposal.
DECISION RECORD
A satellite's recorded decision with its inputs, score breakdown, and citations, downloadable as operator, regulator, and insurer reports. NAVIS advises; the operator retains final authority.
AUDIT LOG ENTRY
A record of a sensitive organization action — API keys, members and invites, private assets, or marking satellites for disposal — capturing the actor, target, and timestamp.
