Goal of this Channel: Gather new ideas for future PNT demonstrator missions
FutureNAV Programme is an ESA initiative with the focus on maturing and demonstrating innovative system concepts and upstream technologies to ensure Europe remains a global leader in resilient PNT solution. The objectives are to:
- Advance the European capabilities in the field of Satellite Navigation
- Respond to the challenges of Global digital mobility
- Secure strategic capabilities for independent European satellite navigation infrastructure and services, through support to the early development of advanced satellite navigation technology which has the potential to support operational missions, both private commercial as well as institutional Programmes defined by the European Union
- Support Europe in remaining a leader in the world-wide space-based PNT scene and support Europe international cooperation through standardisation aiming at interoperability of systems for the benefit of users world-wide
- Strengthen European Satellite Navigation industrial competitiveness and secure highly qualified employment
- Respond to the needs expressed by the scientific / geodetic communities to extend the benefits provided by GNSS-based geodetic techniques in the navigation, scientific and societal domains
FutureNAV comprises of the following components:
- Component 1: Celeste (LEO-PNT)
- Component 2: Genesis
- Component 3: PNT Demonstrators
FutureNAV Component 3 comprises a set of PNT demonstrator missions exploring new system concepts and leveraging PNT technologies and solutions that could have a potential impact on space-based PNT users and services. So far, two PNT demonstrators are under development:
- OpSTAR: an In-Orbit Demonstrator (IOD) of optical inter-satellite link capabilities for PNT
- NovaMoon: lunar-based local differential, selenodetic/geodetic and timing station, enhancing Moonlight lunar PNT services and support lunar scientific experimentation
It is supported by transversal Phase 0/A/B1 activities to define and prepare future PNT demonstrators through (feasibility) studies and critical pre-developments. Benefits include early engagement with industry on PNT innovation, further maturing (e.g. raising TRLs) of individual building blocks and the development of advanced PNT system concepts that will help building a strong foundation for subsequent demonstrator missions.
Two Phase 0/A/B1 activities have been identified as part of the first approved work plan:
- Quantum-Enabled PNT Demonstrator
- AI & Payload Digital Technologies PNT Demonstrator

This open call for ideas channel is related to Phases 0/A/B1 of Future PNT Demonstrators under FutureNAV Component 3.
Some examples of ideas already identified include:
- PNT Integrity
- Multi-layer time synchronisation
- Orbital relative navigation
- Quantum-secured ranging
- Software-defined atomic clocks
- Laser ranging
- Solar system navigation
ESA invites submissions on these and other disruptive, early‑stage ideas and technologies with advanced end-to-end PNT system concept that can shape the future satellite navigation.
We are seeking ideas to develop and validate complete PNT system concept for new In-Orbit Demonstrator (IOD) missions, guided by the consideration of operational PNT system performance key Figure of Merits, such as but not limited to and in no particular order:
- Autonomy
- Availability
- Integrity
- Positioning and timing performance
- Resilience to perturbations
- Security
Your submitted idea(s) may lead to Future PNT Demonstrators Phase 0/A/B1 activities and follow-on Phase B2/C/D/E IOD with the potential to become a new or contribute to an existing operational systems.

Process and Outcome:
1. Submit an idea on OSIP (this channel):
Ideas submitted via the OSIP form are treated as private / commercial in confidence. The ideas will not be disclosed or circulated outside of ESA and will only be visible to a selected group of ESA experts who will be responsible for assessing the suitability of the ideas received.
Anyone is encouraged to submit ideas from research institutes and companies to any entities interested. While anyone can submit an idea, the submission entity must be registered in an ESA Member State, Associate Member or Cooperating State.
Consolidation & selection process is conducted periodically. Ideas submitted prior to 30th September 2026 may be considered in the upcoming process.
ESA will organise workshops to enable industry and research institutes to get together to work on new ideas & foster new collaborations.
Next workshop is planned at the European Space Deep-Tech Innovation Centre (ESDI) in Switzerland on 9th September 2026. However, you are encouraged to submit idea(s) before attending the workshop. This gives us an indication on the number of ideas and topics to organise an efficient workshop. Ideas can still be fine-tuned after submission.
2. Elaboration & consolidation of ideas:
Ideas will be further elaborated into demonstrator concepts as input to work plans for consolidation with ESA Member States at Programme Board on Satellite Navigation (PB-NAV).
3. Selection
Selected demonstrators may lead to the Invitation to Tender (ITT) for Phase 0/A/B1 studies related to the submitted idea(s), to which industry and research institutes are welcome to submit full proposals.
