    According to tracking data from stations of the International GNSS Service’s Multi-GNSS Experiment, the second Russian Luch satellite, Luch-5B, started transmitting GLONASS and GPS differential corrections on January 17, 2013, at around 11:07 UTC.

    Luch-5B, launched on November 2, 2012, carries a transponder for the System for Differential Correction and Monitoring satellite-based augmentation system. The satellite, occupying an orbital slot at 16 degrees west, uses PRN code 125. Transmission tests are not continuous.

  • Luch-5B Arrives at Orbital Slot

    The second Russian SBAS satellite, Luch-5B, has now been positioned at its designated orbital slot of 16 degrees west longitude. The satellite had been in a drift orbit since its launch on November 2 at 21:04:00 UTC along with the domestic communications satellite Yamal-300K.

    Tracking data from NORAD/JSpOC showed Luch-5B arriving at its geostationary position by about December 13. The footprint of the satellite is shown below with the elevation-angle contours at 30-degree intervals.

    Luch-5B is expected to use PRN code 125.

    Luch-5B, the second of a set of three geostationary satellites being launched to reactivate Roscosmos’s Luch Multifunctional Space Relay System, has been delivered to the Baikonur Cosmodrome. It arrived together with the Yamal-300K satellite in a single shipping container aboard an Antanov An-124-100 Ruslan flight from Krasnoyarsk.

    This marked the first time that Information Satellite Systems – Reshetnev has used the special container, which is large enough to carry two middle-class spacecraft at one time. According to the company, sophisticated equipment fitted with a control system that helps monitor the environment inside the container helps avoid any chances of external damage or unwanted environmental impact during transportation.

    Luch-5B is now undergoing preparations for launch.

    The Luch system will be used to relay communications and telemetry between low-Earth-orbiting spacecraft, such as the the Russian segment of International Space Station, and Russian ground facilities.

    The system’s satellites also carry transponders for the System for Differential Correction and Monitoring (SDCM), Russia’s satellite-based augmentation system. The transponders will broadcast GNSS corrections on the standard GPS L1 frequency using C/A PRN codes assigned by DoD’s Global Positioning Systems Directorate.

    As previously reported, Luch-5A, which was launched on 11 December 2011, has been placed in an orbital slot at 95 degrees east longitude. It began transmitting corrections on July 12, 2012, using PRN code 140.

    Luch-5B, scheduled for launch on September 7, 2012, will be positioned at 16 degrees west longitude.
