apologies, I thought GLONASS was military use, I then checked and got stuck in wikipedia, meaning to come back and edit my comment, too late now though.

If you have a recent smartphone, you might be a GLONASS user and not even know it!

If it's an Android smartphone, recent versions of MobiWIA - Eclipsim's GPS Status & Toolbox app divide the satellite signal bar display into four sections (GPS, GLONASS, Beidou, and Galileo). Since my phone only supports GPS and GLONASS, the latter two don't show any bars.
