  METSAT 1 was an Indian (ISRO) meteorological, geostationary satellite that was launched by an upgraded, four-stage PSLV-C4 rocket. The satellite was manoeuvred from the transfer orbit to a geostationary postion at 37° E longitude on September 16, and then was parked at 74° E longitude on September 24. As of 2007 Mar 11 located at 74.00E drifting at 0.007W degrees per day.

Apogee: 35,806 km (22,248 mi). Perigee: 35,768 km (22,225 mi). Inclination: 0.10 deg. Period: 1,436.10 min. Communications satellite; used on-board propellant to reach geosynchronous position..

• IRNSS-1A - . Mass: 1,425 kg (3,141 lb). Nation: India. Class: Navigation. Type: Navigation satellite. Spacecraft: I-1K. USAF Sat Cat: 39199 . COSPAR: 2013-034A. Apogee: 35,866 km (22,286 mi). Perigee: 35,706 km (22,186 mi). Inclination: 27.35 deg. Period: 1,436.06 min. First Indian operational navigation satellite, beginning the Indian Regional Navigation Satellite System. Provides L-band and S-band navigation signals..

• IRNSS-1B - . Mass: 1,425 kg (3,141 lb). Nation: India. Class: Navigation. Type: Navigation satellite. Spacecraft: I-1K. USAF Sat Cat: 39635 . COSPAR: 2014-017A. Apogee: 35,883 km (22,296 mi). Perigee: 35,688 km (22,175 mi). Inclination: 30.89 deg. Period: 1,436.03 min.

  Second dedicated navigation satellite for the Indian Regional Navigation Satellite System. After a coast phase the fourth stage ignited to accelerate the vehicle to a 269 x 20,558 km x 19.3 deg transfer orbit. IRNSS-1B used its onboard engine to join IRNSS-1A in circular inclined geosynchronous orbit, and on April 17 was in a 35,565 x 35,878 km x 31.0 deg orbit over the Indian Ocean.

• IRNSS-1C - . Mass: 1,425 kg (3,141 lb). Nation: India. Class: Navigation. Type: Navigation satellite. Spacecraft: I-1K. USAF Sat Cat: 40269 . COSPAR: 2014-061A. Apogee: 35,879 km (22,294 mi). Perigee: 35,696 km (22,180 mi). Inclination: 4.17 deg. Period: 1,436.14 min. India's third dedicated navigation satellite. Stationed in geosynchronous orbit at 83 deg east..

• IRNSS-1D - . Mass: 1,425 kg (3,141 lb). Nation: India. Class: Navigation. Type: Navigation satellite. Spacecraft: I-1K. USAF Sat Cat: 40547 . COSPAR: 2015-018A. Apogee: 35,869 km (22,287 mi). Perigee: 35,707 km (22,187 mi). Inclination: 30.11 deg. Period: 1,436.18 min. Fourth Indian Regional Navigation Satellite System satellite; joined its siblings IRNSS-1A and 1B in inclined synchronous orbit..

• IRNSS-1E - . Mass: 1,425 kg (3,141 lb). Nation: USA. Class: Navigation. Type: Navigation satellite. Spacecraft: I-1K. USAF Sat Cat: 41241 . COSPAR: 2016-003A. Apogee: 20,547 km (12,767 mi). Perigee: 288 km (178 mi). Inclination: 19.20 deg.

  India launched its 5th navigation satellite. The PSLV-XL delivered it to a subsynchronous transfer orbit. By early February it was in an inclined synchronous orbit at 35697 x 35874 km x 28.1 deg. IRNSS-R1C was in an near-equatorial orbit at 83E; the remainder are in the 28 degree inclined orbits, with R1A and R1B over about 55E and R1D and R1E over about 112E.

• IRNSS-1F - . Mass: 1,425 kg (3,141 lb). Nation: USA. Class: Navigation. Type: Navigation satellite. Spacecraft: I-1K. USAF Sat Cat: 41384 . COSPAR: 2016-015A. Apogee: 35,750 km (22,210 mi). Perigee: 33,349 km (20,722 mi). Inclination: 5.30 deg.

  Indian Regional Navigation Satellite System was augmented by launch of the 1F satellite. The initial insertion orbit was 270 x 20649 km x 17.9 deg; an initial perigee burn to raise apogee was followed by several apogee burns towards circular inclined synchronous orbit.
