I wasn't there at breakfast so missed the conversation.
NAVSTAR which is the American system has global cobverage and is what our GPS
systems decode.
There are some of the newer smart phones and tablets that will use both NAVSTAR
and GLONASS
Very interesting reading especially if you start going to all the external links

Subject: [karc] GLONASS coverage and orbit
There was some discussion this morning at breakfast about the Russian GLONASS
navigation satellite constellation's northern coverage and also the orbit.
From Wikipedia:
"The satellites are located in middle circular orbit at 19,100 km
altitude with a 64.8 degree inclination and a period of 11 hours and
15 minutes. GLONASS' orbit makes it especially suited for usage in high
latitudes (north or south), where getting a GPS signal can be problematic".
