STANDARD CALL FOR PROPOSALS
Under NAVISP Element 2, the permanent Standard Call for Proposals focuses on developing innovative competitive products in the Position, Navigation and Timing domain, in particular, Satellite Navigation.
The objective is to boost Participant States industrial competitiveness in the fast- evolving Position, Navigation, and Timing sector.
NAVISP Element 2 welcomes proposals from space and…
Support for Institutional Projects
Element 3 supports Participating States in advancing national Positioning, Navigation and Timing initiatives across the full value chain. It provides ad-hoc assistance per country or domain to develop and promote GNSS and broader PNT-based products, applications, and services.
Next to funding, ESA may offer technical support in programme management, infrastructure development, and testing…
134: All-weather Laser Timing and Ranging Links for Optical PNT Systems
Optical laser communication links from satellite to ground are affected by atmospheric conditions. When penetrating through clouds, optical signals suffer from power degradation up to complete loss of the satellite-to-ground link. As a result, optical ground stations (OGS) as used in the OpSTAR activity are not able to establish optical links continuously but will instead have data gaps. The…
133: Resilient PNT by a combined GNSS/eLoran/INS approach for U-space applications
EC Regulation 2021/664 defines a minimum set of requirements for the Unmanned Aircraft Systems (UAS) operations in certain geographical zones, which is called U-space. U-space defines new services relying on a high level of digitalisation and automation, designed to provide access to airspace for large numbers of unmanned aircraft.
Emerging U‑space Beyond Visual Line of Sight (BVLOS)…
132: Development and Validation of Flexible eLoran/GNSS signal simulator
Global dependence on GNSS for PNT has exposed threats from jamming, spoofing, interference, and space‑weather effects. These threats are now widely recognised by defence, maritime, aviation, and critical infrastructure stakeholders as a systemic risk to safety and national resilience.
In response, eLoran has re-emerged internationally as a terrestrial, high‑power, low‑frequency…
131: Chip Scale Optical Atomic Clock for PNT applications
As for ground‑based high‑performance clocks, the exploitation of atomic optical transitions represents a promising approach to improving the accuracy and stability of very compact atomic clocks, down to 10 ns per day, with short‑ to medium‑term stability ten times better (or more) than existing products.
While the main bottleneck of this technology lies in the availability of compact…
130: Robust GNSS Tracker for Sensitive Applications
The International Atomic Energy Agency (IAEA) safeguards system is designed to verify States’ legal undertakings to use nuclear material for exclusively peaceful purposes. States declare their nuclear material and activities to the IAEA, and the IAEA verifies the correctness and completeness of these declarations.
This requires robust and resilient GNSS trackers which can withstand…
129 - Identification of Growth Opportunities in PNT Consumer Market
The global GNSS market is predicted to grow considerably in the next decade, with revenues coming from the sale of devices and even more services, and the wider PNT domain revenues are even bigger. Europe share in this market is around 23%, mostly in the professional markets, and it is not expected to increase. Except for few manufacturers located in Europe (e.g. uBlox and STM), the consumer…
128 - Resilient PNT Critical National Infrastructure case study
The rationale and context for this study are similar to as “EL1-120: Resilient PNT Critical National Infrastructure validation test bench”.
One of the considerations that can be derived by the analysis of the context is that the extent of the exposure of CNIs operators and suppliers to the risks posed by intentional and unintentional, natural and man-made RF interference threats is not very…
127 - Cross-Domain Nonlinear State Estimation for Autonomous Systems Using Unscented Kalman Filtering
Autonomous systems, whether operating on land, in the air, at sea, or in structured indoor environments, require robust, real-time state estimation to navigate complex, dynamic, and GNSS-challenged conditions. Traditional estimation techniques such as the Extended Kalman Filter (EKF) often rely on local linearization of the system dynamics and measurement models, which can result in degraded…
