    Frequency-Stable Laser System for Space Could Be Used for Optical Satellite Navigation

    Scientists report that an active optical frequency reference based on molecular iodine was successfully tested for the first time in space. Results of the JOKARUS experiment could be a step toward laser interferometric distance measurements between satellites, and future global navigation satellite systems based on optical technologies.
