On Tuesday, January 11, 2022, Telespazio UK, teaming up with Chronos Technology Ltd. presented the results of the project “RESILIENT, TRUSTWORTHY, UBIQUITOUS TIME TRANSFER” which were achieved through the support of the NAVISP program. About 50 people from industry and research followed the interesting presentation and the subsequent Q&A session.

In recent years, it has become increasingly evident that GNSS data are subject to various weaknesses that can affect, in particular, the accuracy, trustworthiness, resilience, and ubiquity of timing data. The main GNSS weaknesses that can cause service outages and weak signals at the end-user level include space weather, constellation errors, or radio frequency interference such as jamming, spoofing, or meaconing. However, secure and reliable time transfer is necessary to enable the next generation of services worldwide, such as mobile broadband (5G), mobile multimedia transmission, power grids, terrestrial positioning services, financial operations, IoT, Big Data, and cloud processing.

As part of NAVISP Element 1, which aims to develop innovative concepts, techniques, technologies, and systems related to the PNT sector along the entire value chain, Telespazio's main objective was to develop an innovative hybrid timing “system-of-systems”, focusing on the use of complementary GNSS technologies leading to a resilient timing solution on the user side.

To this end, Telespazio UK has succeeded in evaluating and incorporating the capabilities of several key components into a Hybrid Timing System according to specific use cases. Included key components covering Multi-Constellation and Multi-Frequency (MCMF) receivers, 5G and Satellite Time and Location (STL) data as well as the use of Enhanced Loran (eLoran), Precision Time Protocols (PTP), GNSS Firewall (BlueSky) and Chip Scale Atomic Clocks (CASSC).

Now that Telespazio can assure the feasibility and added value of such technology, the company established a two-year development plan that includes prototype demonstration and system qualification in an operational environment, followed by potential commercialization of the product.
