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…
112 - Development of a GNSS Receiver Size Weight & Power Model
In recent years, the design of GNSS receivers has become increasingly complex due to ongoing developments in signal structures and the growing variety of carrier frequencies, bandwidths, waveforms, chipping, and data rates. Based on these parameters and on the advancements in the different application domains, no effective, comprehensive tool currently exists to evaluate the best trade-off in…
111 - Managing GNSS Local Effects in the Railway Environment for Advanced Safe Train Positioning
The European Rail Traffic Management System (ERTMS) is a single European signalling and speed control system that ensures interoperability of the national railway systems throughout the single European railway area. ERTMS is comprised of the European Train Control System (ETCS, an in-cab signalling system that includes Automatic Train Protection – ATP) and a track to train radio communication…
110 - User Equipment Platform for Positioning with 5G/6G Non-Terrestrial Networks
The future 5G and 6G non-terrestrial networks (NTN) will offer continuous and ubiquitous coverage, serving predominantly terrestrial users in remote and underserved areas. The latest 3GPP releases imply that the user equipment (UE) must be equipped with the Global Navigation Satellite System (GNSS) receiver determining its position, velocity, and time (PVT) to be able to connect to NTN. To…
109 - 5G Localisation for Safety of Life Applications in Rail
Safe Localisation of railway vehicles is necessary to allow train control systems to operate. Today this is done within the European Train Control System (ETCS) by using fixed location tags called Eurobalises and odometry sensors.
While Eurobalises typically are safe, fairly accurate and robust, they impose high costs for installation and maintenance on the infrastructure operator and only…
108 - Assessment of Time Transfer Techniques for Resilient Regional (Transnational) UTC Infrastructure
Timing is a highly important use case of GNSS, as many sectors such as telecommunications, emergency services, transport and finance depend on precise time to operate correctly. Therefore, there is a need to provide Critical National Infrastructure (CNI) with accessible, resilient sources of precise reference time using time transfer techniques which are complementary to GNSS. The time reference…
107 - Ultra high spatial resolution GNSS receiver for automotive industry
The ability of exploiting the spatial dimensions has allowed array antennas to be exploited in various applications. Over the past years, array antennas have been deployed in GNSS receivers either to provide a spatial filter or to improve the signal-to-noise ratio (SNR) using beamforming techniques.
To achieve a high spatial resolution, a large array antenna aperture should be used. The…
106 - Beamforming user antenna for wideband radionavigation signals in C-band
The rapid increase in GNSS RFI (e.g., in Baltic and Scandinavian peninsula there were 122 days with GPS jamming in 2022, and 294 days in 2023) is staggering. Accordingly, in recent years, beamforming techniques have been deployed in GNSS receivers (in the L-band) either to provide a spatial filter or to improve the signal-to-noise-power (CN0) level.
Beamforming techniques can achieve a…
105 - Hybrid black-white-modelling estimation and machine learning algorithms for PNT engines
The application of machine learning (based on “black-box” modelling) is of interest in problems that are difficult to solve based on traditional (optimal) estimators for simple models (“white-box” modelling). Black-box modelling is difficult to be explained and understood (i.e., difficult to understand what to expect in unknown or new situations), involve high computation complexity, and…
