This project outlines a strategic plan of activities to elevate the Technology Readiness Level (TRL) of Precise Positioning and timing receiver for LEO applications (NAVTIME-RX) from TRL 5 to TRL 7. The project is based on SEXTANS receiver heritage and aims to accelerate the development and maturation of the GNSS receiver technology, positioning it closer to commercial readiness through the manufacturing and testing of an Electronic Bread Board (EBB), developing an Engineering Qualification Model (EQM) and enhancing the Software for GNSS signal processing.
