TPT Zenith

Open-source ground station control & orbital routing platform.

Status: Pre-alpha · License: Dual MIT / Apache-2.0 · Owner: TPT Solutions

TPT Zenith is an open-source ground station control system and orbital routing protocol. It manages dish arrays, tracks satellite constellations, and routes data between space-based AI inference nodes and terrestrial TPT Aether basestations. Software-only simulation first; hardware integration is deferred to Phase 7.

Architecture

Component	Language	Phase	Description
Orbital Mechanics Engine	Rust	1	SGP4/SDP4 propagator, visibility windows, handoff optimization
Orbital Routing Protocol	Go	2	DTN / Bundle Protocol (RFC 9171) store-and-forward mesh routing
Antenna Control System	Rust	3	Deterministic tracking loop with a simulated dish backend
RF Signal Processing Pipeline	SDR	4	Modem / error-correction chain (simulation-first)
Space-AI Bridge	Go	5	On-orbit inference API over the DTN routing layer
TPT Ecosystem Integration	—	6	Handoff interfaces to Aether, DataCenter, Sentinel

Roadmap

Phased plan lives in todo.md:

• Phase 0 — Repo, licensing, CI (this phase)
• Phase 1 — Orbital mechanics engine (Rust)
• Phase 2 — Orbital routing protocol (Go, DTN)
• Phase 3 — Antenna control system (Rust, simulated)
• Phase 4 — RF signal processing pipeline (SDR, simulation-first)
• Phase 5 — Space-AI bridge (on-orbit inference)
• Phase 6 — TPT ecosystem integration
• Phase 7 — Hardware-in-the-loop (future)

Building

Rust workspace

cargo build
cargo test

Go module

go build ./...
go test ./...

Orbital routing demo (Phase 2)

Run the DTN store-and-forward harness with its built-in intermittent-mesh scenario:

go run ./routing/cmd/zenith-dtn

Or drive it with a contact plan exported from the Phase 1 orbital-mechanics engine (visibility windows → DTN contacts), demonstrating the end-to-end Phase 1 → Phase 2 data flow:

cargo run -p orbital-mechanics --bin export_contacts > contacts.json
go run ./routing/cmd/zenith-dtn -plan contacts.json \
    -src dtn://ground-tokyo/out -dst dtn://ground-kauai/inbox -payload "hello"
