Start date: 01/09/2022Date of Completion: 28/02/2024Global Navigation Satellite Systems (GNSS) have become the primary marine aid-to-navigation and source of Position, Navigation and Timing (PNT) information. Yet, all GNSS are vulnerable to natural interference, deliberate and accidental jamming and spoofing. Trials have demonstrated that degraded GNSS produce hazardously misleading information and erroneous vessel positions without an alarm being…Prime contractor

Start date: 19/05/2021Date of Completion: 21/05/2021Position uncertainty during autonomous manoeuvres such as orbit-raising/de-orbiting requires that the local knowledge during low thrust (i.e. with electric propulsion) is accurately determined. Current orbit-raising assumes semi-autonomous control assisted by GNSS, with a long time integral to measure increasing altitude and trajectory of the satellite. The use of a hybrid GNSS unit that…Prime contractor

Start date: 04/04/2018To find a presentation summarizing the now completed activity, click here. The project is the development of a new type of smartgrid distribution automation sensor platform which uses high speed waveform analysis and high accuracy time stamping to provide electricity Distribution Network Operators (DNOs) with detailed high fidelity information about the operation of their distribution… -
Start date: 02/05/2018To find a presentation summarizing the now completed activity, click here and to find the abstract, click here. The use of Global Navigation Satellite System (GNSS) satellite based navigation is ubiquitous where signals are used for both precision position and timing information. All systems, be they established or emerging, exploit predominantly low power, spread spectrum signals (typically… -
Start date: 09/04/2020Final Presentation Executive Summary Report ERTMS is an EU initiative with the aim of improving safety and increasing interoperability of rail transport through a Europe-wide standard for train control and command systems, replacing existing national systems. ERTMS consists of two parts: the European Train Control System (ETCS), an automatic train protection system providing in-cab train… -
Start date: 30/04/2020GNSS is the only global, free, comprehensive technology providing absolute PNT data to users worldwide. Its limitations are known, including long life cycle and replenishment schedule, affecting their ability to adapt easily to short-term market needs and to some extent, resilience. Considering the above, alternative PNT methods and solutions have been developed or are being investigated,…Prime contractor

Start date: 07/10/2019In the last years, there has been fast progress in satellite on-board computing achieved by the satellite telecommunication industry. On-board processors are more performant, with less mass, volume and power consumption. As regards current and evolving space-based PNT data layer services (e.g. private or public GNSS data augmentations), they usually retransmit data computed on-ground via…Prime contractor

Start date: 14/10/2020GNSS simulations are an important toolset supporting system engineering trade-offs and decisions. They are used to display and monitor key system performance indicators as well as study system behaviour, both through synthetic scenarios and real data replay. Industry and ESA currently use different tools to simulate GNSS systems, however often constrained to undertake only one of two different… -
Start date: 23/01/2023There is an abundance of GNSS receivers deployed around the world providing measurements and PNT information, which are currently combined into networks for a variety of GNSS processing and monitoring applications. However, these receivers remain vulnerable and cannot be used to isolate all sources of error on all GNSS signals and constellations due to the processed nature of the receiver output,… -
Start date: 04/03/2023AIPLAN is developing new PNT user segment products that provide comprehensive, indicative, and cost-effective solutions to structural & environmental monitoring thereby reducing cost and time, as compared to current ground motion & infrastructure survey solutions (i.e. multiple manual surveys and ground boring techniques). AIPLAN will provide high accuracy measurements of site settlement &…Subcontractors
