Does the new TomTom range support Glonass GPS Satellites ?

Glonass support has been out for a while now with other GPS devices (Samsung S4 :-) )..

GPS acquisition is just sooo much faster with it.....

 

Does anybody know if the new TomTom range support Glonass ?

    Hi jflet1

    The new TomTom GO range uses both GPS and GLONASS simultaneously for positioning.

    GLONASS is widely regarded to be more accurate than GPS.

     

    Regards

    Excellent :D

    Thanks for the prompt reply......

    Two amazing things -

    1 Glonass is supported !!

    2 TomTom marketing have completely failed to mention a major new fantastic feature to the TomTom Go range....

    When can I buy the latest TomTom GO?

    Hi,

    @Waszko80: TT has not given any date yet. The presentation was just the opening to make these devices publicly known for the first time. Therefore the devices won't be completely finished yet. Just like with every other major presentation in our technical world.
    As soon as the devices are finished for release they will be released but as of now there's no definite date known.

    There are though some rumors in the forum so if you look careful you might find one. But as those are only rumors there's no guarantee that the dates are correct.


    Regards
    Lars.

    Hi all,I just stumbled on this comment and I need to make a small correction here. As a standalone constellation, Glonass is not more accurate than GPS. It's difficult to put a precise number on this, because the local conditions play such a big part in this, but on average, GPS on its own gives better accuracy than Glonass-only.Part of the reason why it's difficult to figure out how well Glonass performs on its own has to do with the fact that there are virtually no Glonass-only receivers out there. Even Russian receivers are mostly dual constellation.The reason for that is obvious: the real advantage lies in the fact that the dual constellation receiver can access almost twice as many satellites, and this helps a lot in challenging (urban canyon) conditions where you have a limited view of the sky; you simply increase the chance of seeing enough satellites up there, even when you see only a small patch of sky above you.There is also a local advantage that applies to higher lattitudes. The GPS orbits favour visibility more for lower lattitudes (towards the equator), whereas Glonass orbits favour the higher lattitudes, which makes sense when you look at Russia on the map. This means that, the further up you go, the chance of seeing Glonass satellites goes up, and for GPS it goes down (somewhat).This is a classic case of 'more is more'. You see more satellites, so you have more information to calculate your position. As a rule, hybrid (GPS+Glonass) receivers also have more tracking channels, so it can indeed use all those extra satellites up in the sky. Where GPS only receivers can only track about 12 satellites simultaneously (as is the case for TomTom's GPS receivers), because that is about the maximum number of satellites you can expect to see if you only have GPS, the GNSS receiver in our new range can track 18 satellites simultaneously.
