    Well the internal Chinese market is really huge. So compass/Beidou receivers will certainly be available and extremely cheap. Will be interesting to see if GPS and/or Galileo can compete with that.

    In case the systems are truely interoperable the cost for multi system reciever will really be limited. There are already 48 channel chips available today and they can track any system as long as they are truely interoperable.

    I have little knowledge about the Beidou/Compass signals. But for GLONASS it seems that they are heading towards a CDMA system as well. And if the Russians put their mind to something they are usually quite successful. They came to the moon first (not with people but much more effictively with a robot) and GLONASS was in service before GPS was….

    So, I think the GNSS future looks bright and 2008 (and 2009) will be really interesting!

    Agreed!! it looks very bright as competition usually makes things better for sure

    But the hard work is making all of them truly interoperable so that any new navigation message on L1 does not interfere with the GPS/Galileo ones, we will see. otherwise we could get terrible interference and then the situation would actually be worse!! but i doubt they (US and Europe) will let that happen.

    On the russian/chinese capabilities I do not doubt that they are capable but as their internal markets tend to be very limited usually their high-technology, high-precision applications are not top of the world! I think that only when your internal markets are very developed then you produce very high quality precision technology for sustained periods of time. I obviously have a bias in this comment being european!! … For consumer goods we all buy chinese made merchandise, but the features and inventions inside your iPod did not come from China even if was made there! and the same for aircraft, super-computers, brain scanners, mri scanners, high end cars, atomic clocks, etc, etc. But again I have my biases since I live here!!

    in any case I wish everyone all the best and I agree we have a great future in the Satellite Navigation field!

    all the best,
