What TRL does GSTP cover?

GSTP picks technologies up after basic research (roughly TRL 3–4) and matures them toward flight readiness (TRL 6–8), including building and flying demonstrators. It complements ESA's early-research activities on one side and application programmes on the other.

Why do I need my national delegation for GSTP?

GSTP is an optional ESA programme funded by national subscriptions. Activities are supported by the member states that want them, so a proposal effectively needs your national space office to endorse (and fund) it — a letter of support is a standard prerequisite.

What is ESA GSTP?

GSTP (General Support Technology Programme) is ESA's optional programme for maturing space technology: taking components, subsystems and processes from early prototypes to flight-ready products. It is organised around elements commonly described as Develop (mature the technology), Make (productise, including with non-space industry) and Fly (in-orbit demonstration).

How it differs from other ESA routes

Where ARTES is telecom-specific and InCubed is Earth-observation-commercial, GSTP is domain-agnostic hardware maturation — propulsion, materials, avionics, robotics, ground technology. If your deep-tech's blocker is "we need to raise the TRL and prove it in a relevant environment", GSTP is the ESA instrument built for exactly that.

The national-delegation reality

GSTP runs on national subscriptions, and activities need backing from your country's delegation. Practically: before investing in a proposal, talk to your national space office (in Poland — POLSA / the national delegation to ESA) and secure a letter of support. Many strong startups lose months by writing first and asking later.

Activities are published as invitations to tender on esa-star — GSTP-coded calls appear in VIRA's live catalogue alongside everything else: see live tenders.
