Spire to develop flexible geolocation signal-processing tools for ESA

December 8, 2021  - By

Spire logoSpire Global has been awarded a contract under the European Space Agency’s (ESA) Navigation Innovation and Support Programme (NAVISP), specifically “Element 2 – Competitiveness in PNT.” The contract is funded by the United Kingdom Space Agency.

Spire will work with NAVISP to build on the current capabilities of the Spire constellation and develop tools needed for geolocation signal processing, which will be applied toward geolocating GNSS interference sources coming from the Earth’s surface.

Spire’s low-Earth orbit (LEO) nanosatellite technology will be used to collect suspect interfering RF signals from a range of geographic areas prone to disruptions. Using advanced processing algorithms, the project will develop a suite of geolocation signal collection and processing techniques (including single and multi-satellite) to detect and characterize signals from a variety of interference scenarios.

NAVISP Element 2 emphasizes maintaining and improving the capability and competitiveness of the position, navigation and timing (PNT) industry and its technologies and services in the global satellite navigation market. In recent years, PNT services have become ubiquitous and relied on by industry and critical national infrastructure such as telecommunications, emergency services, energy, finance, food and transport. The GNSS signals used in these applications are vulnerable to interference, which can disrupt PNT services.
