Russian GLONASS Down For 12 Hours

An anonymous reader writes "In an unprecedented total disruption of a fully operational GNSS constellation, all satellites in the Russian GLONASS broadcast corrupt information for 11 hours, from just past midnight until noon Russian time (UTC+4), on April 2 (or 5 p.m. on April 1 to 4 a.m. April 2, U.S. Eastern time). This rendered the system completely unusable to all worldwide GLONASS receivers."

  1. Down? Or encrypted? by Anonymous Coward · · Score: 4, Informative

    The system shutting down while still broadcasting "gibberish" seems awfully inconvenient. Sure they just didn't switch to encrypted transmissions?

  2. Re:How does this affect dual-system chipsets? by Guppy · · Score: 5, Informative

    Newer phones have location chipsets that support both GPS and GLONASS. Do they figure out automatically that the GLONASS information is bad and switch to using GPS exclusively?

    To promote their system, Russia decided to make new smartphones without GLONASS support illegal in their country -- so major manufacturers added that capability to all their phones (since there is almost no additional cost to each unit, once the capability is designed into the chipset). Not sure about CDMA chipset, since there is no major CDMA networking in Russia.

    Would be nice if we got Galileo GNSS and Beidou support too, but I'm not expecting it to happen unless they pull a similar stunt with their markets (well, China might).
