How LTL.ai is put together.

A layered architecture that maps to how missions actually run. Each layer is independently scalable, independently testable, and replaceable when the underlying technology changes.

EXPERIENCE LAYER

Console, APIs, SDKs, ChatOps

Multi-asset mission console (web + native), versioned REST and gRPC APIs, language SDKs (Python, Go, TypeScript, C++), Slack/Teams ChatOps adapters, and a notification router.

INTELLIGENCE LAYER

TACK — Trajectory-Aware Command Kernel

Reasoning core: continuous-thrust planner, simulation orchestrator, policy validator, approval workflow engine. Stateless services backed by event sourcing.

DATA LAYER

Asset Twin & Telemetry Lake

Per-spacecraft digital twin store, hot/warm/cold telemetry tiers, time-series query engine optimized for sub-second cross-asset queries, schema registry.

CONNECTIVITY LAYER

Ground Network Bridge

Pluggable adapters for ground stations, GEO relays, and partner networks (KSAT, Viasat RT, AWS Ground Station, USSF SCN). Pass scheduler, contact manager, signed uplink pipeline.

FOUNDATION

Secure Multi-Tenant Substrate

FIPS 140-2 cryptography, sovereign and air-gapped deployment options, signed audit log, hardware-key-backed RBAC, per-tenant network isolation.

DESIGN PRINCIPLES

Five things that shaped every layer.

DETERMINISTIC OPS

Same inputs, same outputs. No hidden state, no implicit ordering, no flake.

EVENT SOURCING

Every change is an event. State is derivable. Audit is intrinsic, not bolted on.

POLICY AS CODE

Mission constraints are reviewable, testable, version-controlled artifacts — not buried in workflows.

BLAST RADIUS

Per-tenant isolation. Per-asset rate limits. Per-region failure domains. Bad days stay small.

REPLACEABILITY

Each layer has a defined contract. Ground network adapters, solvers, twins — all swappable.
