  • Galileo: no way without time
    on March 10, 2023 at 1:55 pm

    Europe’s Galileo is the world’s most precise satellite navigation system, providing metre-level accuracy and very precise timing to its four billion users. An essential ingredient to ensure this stays the case are the atomic clocks aboard each satellite, delivering pinpoint timekeeping that is maintained to a few billionths of a second. These clocks are called atomic because their ‘ticks’ come from ultra-rapid, ultra-stable oscillation of atoms between different energy states. Sustaining this performance demands, in turn, even more accurate clocks down on the ground to keep the satellites synchronised and ensure stability of time and positioning for users.  

  • Navigation Lab exploring Galileo’s future – and beyond

    Would you like to know the future of satellite navigation? Try ESA’s Navigation Laboratory. This is a site where navigation engineers test prototypes of tomorrow's user receivers, using simulated versions of the navigation signals planned for the coming decade, such as set to be transmitted from Galileo’s Second Generation satellites. 

  • Guide morphing rovers across alien world in evolutionary computing contest
    on March 7, 2023 at 12:04 pm

    Thousands of years from now, the descendants of humankind gather via a galactic network of wormholes to begin the joint exploration of a curiously Mars-like world in deep space. A constellation of quantum communication satellites serve to oversee the progressive mapping of this terra incognita by AI rovers, which are capable of morphing their shape to traverse the most challenging terrain imaginable.

  • Harvesting Data from the NASA STI Repository
    on March 25, 2021 at 11:46 pm

    Harvesting Data from the NASA STI Repository The STI Repository promotes the dissemination of NASA STI to the widest audience possible by allowing information to be harvested. In support of these objectives, the upgraded repository has an OpenAPI to provide greater access to publicly available data and further flexibility for dissemination of NASA research results. The OpenAPI is the recommended mechanism for access to NASA’s public collection of STI, and is available along with the following API documentation and guidance:

  • For Developers

    For Developers NASA API’s launch makes NASA data, including imagery, eminently accessible to application developers. The NASA STI Repository OpenAPI is the recommended mechanism for access to NASA’s public collection of STI, and is available along with API documentation and guidance. What is STI? STI (scientific and technical information) is defined as a paper, abstract, journal article, presentation, etc. that contains and delivers the results (the analyses of the data, facts, and resulting conclusions) of basic and applied scientific, technical and related engineering research and development.

    The NASA STI Program The NASA Scientific and Technical Information (STI) Program is a critical component in the worldwide activity of scientific and technical aerospace research and development. The NASA STI Program acquires, processes, archives, announces, and disseminates NASA STI and acquires worldwide STI of critical importance to NASA and the Nation. Collected from U.S. and international sources, STI is organized according to content prior to being added to the NASA STI Repository (NTRS) launch .
