that's fine. i'm sure GLONASS is also not as good as GPS, because of US's 20 year head start on this, but only 3 countries in the world have an independent global positioning system right now.
I think either you are getting very less information about the world or your govt. telling you less about real things.
1) Two Global GPS system
A) USA(GPS)
B) Russia (GLONASS) (Joined by India for military grade)
2) Regional GPS
A) China - Beidou 1
B) France- DORIS
C) India - IRNSS- to be completed by 2013-2014
D) Japan- Quasi-Zenith Satellite System
3) Global GPS undress Progress:
A) China - COMPASS (to be completed by 2020)
B) Europe - Galileo
A) Glonass : Originally, GLONASS was designed to have an accuracy of 65 m, but in reality it had an accuracy of 20 m in the civilian signal and 10 m in the military signal.
As of 29 December 2011, the GLONASS constellation status is
Total Satellites in Constellation 31 SC
Operational 24 SC (Glonass-M)
In Commissioning 1 SC (Glonass-M)
In Flight-test 1 SC (Glonass-K)
In Maintenance 2 SC (Glonass-M)
Spare 3 SC (Glonass-M)
According to Russian System of Differentional Correction and Monitoring's data, as of 2010, precisions of GLONASS navigation definitions (for p=0.95) for latitude and longitude were 4.46—7.38 m with mean number of NSV equals 7—8 (depending on station). In comparison, the same time precisions of GPS navigation definitions were 2.00—8.76 m with mean number of NSV equals 6—11 (depending on station). C
ivilian GLONASS used alone is therefore very slightly less accurate than GPS. On high latitudes (north or south), GLONASS' accuracy is better than that of GPS due to the orbital position of the satellites.
In order to increase the navigation definition of GLONASS to an a
ccuracy of 2.8 m by 2011. I
n particular, the latest satellite design, GLONASS-K has the ability to double the system's accuracy once introduced.
Glonass K is 3rd gen Sat ,In which India also is share holder by launching and providing money.
