The European Space Agency (ESA) is making strides in integrating optical technology into positioning, navigation, and timing systems. Through a partnership with a European industry consortium, ESA is conducting a study and predevelopment to advance the use of optical technology in satellite navigation. This initiative is part of the FutureNAV program, which aims to innovate and refine navigation technologies for European leadership in the sector.
The proposed in-orbit demonstrator, known as OpSTAR, will validate intersatellite optical links crucial for potential implementation in satellite navigation networks. Optical technology offers improved precision and resilience compared to traditional radio signals, with potential benefits for global navigation services.
The project involves collaboration with 33 companies from ESA Member States, led by OHB System of Germany. The next phase will focus on in-orbit testing to evaluate system concepts and determine the feasibility of integrating optical technology into operational navigation systems.
Optical technology provides the foundation for a more autonomous global navigation satellite system, reducing dependence on space atomic clocks and ground-based infrastructure. With improved data transfer rates and resistance to jamming and spoofing, optical links offer enhanced security for navigation systems.
ESA aims to achieve millimetre-level spatial accuracy and picosecond-level timing precision through optical technology, promising to benefit billions of users worldwide. By involving industry leaders at an early stage, ESA empowers European industry to lead in global navigation technologies and benefit from future implementation.
