SPS and RS in context with NAVIC

NAVIC (Navigation Indian Constellation) provides two types of services viz. Standard Positioning Services (SPS), which will be provided to all users; and Restricted Services – (RS), which will grant access only to authorised users. It is made of seven satellites of which three are in GEO and four are in GCO. With the launch of IRNSS-1G (seventh and final member of IRNSS constellation) the IRNSS system is complete and would be soon operational. IRNSS-1G has a 12-year mission life.
