Today, GPS become a part of
everyday life. Common people are using GPS devices for finding shortest route of
their destinations to for keeping eye on their kids. Usually, people are
unaware about the GPS system; how it works; to whom it belongs. Most common
misconception is that GPS belongs to USA, but the fact is that GPS is a system
and it is implemented as NAVSTAR by USA. This means the current GPS we are
using is USA owned but soon we getting different alternative to NAVSTAR GPS
system as Russia based GLONASS GPS system.
So, GLONASS (GLObal NAvigationSatellite
System) is a satellite navigation system managed by Russia. Alike NAVSTAR,
GLONASS is also provides real time position to military and civilian. Receiving
the GPS signals at high latitudes are very difficult, in such cases GLONASS signals
are useful. GLONASS have regional as well as full global coverage. GLONASS have
same accuracy and precision as NAVSTAR. Many smart phones are NAVSTAR and
GLONASS enabled.
Like Russia, other
countries are developing their own positioning or navigation system. China is
developing COMPASS or Beidou Navigation Satellite System which will be
fully operational by 2020. European Union is building Galileo Positioning
System which will be fully operational by 2019. India is developing two regional
navigation systems - Indian Regional Navigational Satellite System (IRNSS) and GPS
Aided GEO Augmented Navigation (GAGAN). Both systems are planned to be fully
operational by 2014.
This means in near future we will get more option about getting location based information.
