In the context of spaceflight, a satellite is an object which has been placed into orbit by human endeavor. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon.

Stretched Rohini Satellite Series (SROSS)
Lunched by India's Augmented Satellite Launch Vehicle, ASLV, on May 20, 1992 and May 4, 1994 respectively.
IRS-1A Satellite (First Operational Satellite )
This is first indigenously built sun-synchronous polar orbiting satellite.
Orbit Details
Launch date : March 17, 1988 (Soviet Launcher VOSTAK used)
Altitude : 904 Kms.
Inclination : 99.049 degrees
Period : 103.19266 minutes
Repetivity : 22 days
Equatorial crossong time : 10.25 AM descending
Weight : 975 Kg.
IRS-P1 Satellite (Indigenously Launched (P) Series)
IRS-P series are being launched by indigenously developed polar launch vehicle ( PSLV ). Due to failure in last stage of rocket, satellite and rocket were plunged into sea.
This is similar to IRS-1A satellite in all aspects.
Orbit Details
Launch date : August 29, 1991 (Soviet Launcher VOSTAK used)
Altitude : 904 Kms.
Inclination : 99.049 degrees
Period : 103.19266 minutes
Repetivity : 22 days
Equatorial crossong time : 10.25 AM descending
Weight : 975 Kg.
IRS-P2 Satellite (Indigenously Launched (P) Series)
Orbit Details
Launch date : Oct. 15, 1994
Altitude : 817 Kms.
Repetivity : 24 days
This is one of the best satellites having highest spatial resolution of 5.8 m in Panchromatic and 23.5 m in multispectral.
Orbit Details
Launch date : Dec. 28, 1995 (Soviet Launcher Molniya used)
Altitude : 817 Kms.
Inclination : 99.049 degrees
Period : 101.35 minutes
Repetivity : 24 days (5 days - revisit)

Altitude : 817 km.
Inclination : 99.049 degrees
Period : minutes
Repetivity : days
Equatorial crossong time : 10.30 AM descending
Weight : Kg.
No. of Sensors : Two 1) WiFs, 2) MOS (Modular Optoelectronic Scanner)
IRS-1D Satellite (Indigenously launched operational satellite)
Satellite entered in elliptical orbits instead of circular after it was separated from rocket. Due to this problem, there is change in swath, resolution according to orbit distance from the earth center.
Launch date : Sept. 29, 1997 (indigenous PSLV-D4 rocket was used)
Equatorial Crossing time: 10.40 A.M
Altitude : 737 Km(Perigee)/821 Km. (Apogee)

No. of Sensors : Three; 1) PAN, 2) LISS-III and 3) WiFS
Launch Date : May 26, 1999 by indigenous PSLV rocket
Launch Date : Launched on Oct. 17, 2003 PSLV-C5
Launch Date : May 5, 2005 by indigenous PSLV rocket
Launch Date : Jan 10, 2007 by indigenous PSLV-C7 rocket
