Mission Ladder

Personal Satellite Mission Ladder

A source-backed ladder for a compliant learning path: define the boundary, receive before transmitting, reduce the payload question, and keep safety and regulatory review visible.

Reviewed: 2026-06-09Review expires: 2026-12-09

Scope: Personal hobby and learning path for understanding a compliant small-satellite mission. This is not a flight plan, launch booking guide, licensing advice, or safety assessment.

Default boundary: Access to orbit assumes compliant rideshare, hosted payload, or educational/non-profit programs. Self-developed orbital launch is out of scope.

Ladder stages

stage-0-ledgerMission review ledgerCreate a source-backed ledger for goals, boundaries, authorities, and unanswered questions.

Evidence

Personal, not commercial boundary Mission review ledger

Stop condition: If the mission scope becomes commercial, remote-sensing, or public communications service, re-scope before continuing.

stage-1-receive-onlyReceive-only signal literacyUnderstand public satellite pass windows, object identity, and receive-only data provenance without transmitting.

Evidence

Ground pass window TLE tracking Data integrity check

Stop condition: Do not move from receive-only learning into transmission without documented authorization review.

stage-2-ground-segment-boundaryGround segment boundaryDescribe the ground station, network handoff, and data integrity path at a conceptual level.

Evidence

Ground station Network handoff Frequency authorization

Stop condition: No actionable RF configuration is recorded in this registry.

stage-3-hosted-payload-questionHosted payload questionTest whether the personal objective can be reduced to a hosted payload instead of a full spacecraft.

Evidence

Payload definition Hosted payload Payload integration review

Stop condition: If the objective requires operator control of a full spacecraft, escalate the safety and regulatory review.

stage-4-spacecraft-minimumsSpacecraft minimumsMap power, thermal, avionics, safe-mode, and deployment risks before treating a spacecraft as credible.

Evidence

Power budget Thermal budget Onboard computer Safe mode Antenna deployment

Stop condition: No hardware design is treated as flight-ready from this registry.

stage-5-orbit-and-disposal-boundaryOrbit and disposal boundaryPair orbit selection with debris mitigation and disposal planning before any access-to-orbit discussion.

Evidence

Orbit selection Orbital debris mitigation Deorbit / disposal plan

Stop condition: No orbit is acceptable only because it is convenient for ground contact.

stage-6-leo-verified-messageLEO verified messageFrame the first orbital success criterion as a small, authenticated, logged message from LEO.

Evidence

LEO verified message Telemetry beacon Data integrity check Mission review ledger

Stop condition: A verified message is not proof of legal authorization, mission safety, or commercial readiness.

Regulatory registry

Boundary references for authorization and review questions.

Federal Aviation AdministrationPayload review and launch/reentry public-interest boundaryAsk whether the payload owner/operator and launch applicant have all required licenses, authorizations, and permits before treating access to orbit as real.
