The Ariane Passenger Payload Experiment (APPLE) was ISRO's first indigenous, experimental communication satellite. It was launched into GTO (Geosynchronous Transfer Orbit) by the third development flight of ESA'a Ariane vehicle from Kourou on June 19, 1981.
From the experimental satellite Aryabhatta launched in 1975, to RISAT-2BR1 in 2019, India's space odyssey has spanned 44 years and over 100 satellites. The below slideshow highlights India's space launches over the years.
“The revenue we earn through foreign satellite launches is only 10% to 20% on average, while more than 75% of our revenue comes from satellite communication business. And, in the said period, Isro launched 99 satellites — 69 of which were foreign satellites — including several student and university satellites.
ISRO has put into operation two major satellite systems: the Indian National Satellites (INSAT) for communication services, and the Indian Remote Sensing Programme (IRS) satellites for management of natural resources.
ISRO's Polar Satellite Launch Vehicle, PSLV-C24, successfully launched IRNSS-1B, the second satellite in the Indian Regional Navigation Satellite System (IRNSS), today evening (April 04, 2014) at 1714 hours IST from Satish Dhawan Space Centre SHAR, Sriharikota.
With a mission life of 15 years, GSAT-30 is an operational communication satellite for DTH, television uplink and VSAT services. The Bengaluru-headquartered ISRO has said the communication payload of GSAT-30 is specifically designed and optimised to maximise the number of transponders on the spacecraft bus.

India's telecommunication satellite GSAT-30 was successfully launched into a Geosynchronous Transfer Orbit (GTO) on January 17, 2020 from Kourou launch base, French Guiana by Ariane-5 VA-251.
Who owns our orbit: Just how many satellites are there in space? There are nearly 6,000 satellites circling the Earth, but only 40% are operational.
Polar Satellite Launch Vehicle (PSLV) is the third generation launch vehicle of India. It is the first Indian launch vehicle to be equipped with liquid stages.
A Black Moon (in some parts of the world)18 is a Black Moon. Officially, it occurs at 10:41 p.m. EDT (0241 GMT Aug. 19). The next Black Moon won't arrive until April 30, 2022, and it will be the second new moon in a single calendar month.
Satellites do not have their own lights that make them visible. What you will see is sunlight being reflected off the satellite, often off the large solar arrays that provide power to the satellites. It is a large object with large, highly reflective solar panels making it the brightest of human objects orbiting Earth.
NASA is one of the most successful space agency on the earth with a higher number of successful space missions. ISRO is more efficient and leading space agency on earth. The biggest difference is the annual budget for space missions. NASA has more budget for space missions as compared to ISRO.
One aspect of their overwhelming success is the absence of the bureaucratic hurdles and hierarchies that are present in almost any government body. Another important reason that has attributed to their success is the fact that specialists in the field and technocrats — starting with Mr Vikram Sarabhai himself .
About the Launch VehicleGeosynchronous Satellite Launch Vehicle Mark II (GSLV Mk II) is the largest launch vehicle developed by India, which is currently in operation.
NASA stands for National Aeronautics and Space Administration. It is a USA government agency that works for the civilian space program as well as for aeronautics, scientific discovery, Earth and aerospace research.
In 1975, all sounding rocket activities were consolidated under the Rohini Sounding Rocket (RSR) Programme. RH-75, with a diameter of 75mm was the first truly Indian sounding rocket, which was followed by RH-100 and RH-125 rockets.
Spacecraft mainframe remained active till March 1981. Due to orbital decay the satellite entered Earth's atmosphere on 11 February 1992.

New Delhi: China today launched two satellites for Pakistan that, among other things, are meant to keep an eye on India. One of them -- the PRSS-1 -- is a remote sensing satellite built by China. The other -- PakTES-1A - is Pakistan's indigenously developed scientific experiment satellite.

The Indian Space Research Organization (ISRO) launched 104 satellites into orbit aboard the Polar Satellite Launch Vehicle on Feb. 14, 2017, setting a new record for the most satellites launched simultaneously on one rocket.
No explosives are needed; at orbital speeds, kinetic energy does the damage. The idea of shooting down satellites has been around as long as satellites have. The first (failed) ASAT test, by the US, was back in 1958, less than a year after the launch of Sputnik. China's own first successful ASAT test was in 2007.
While a number of countries have built satellites, as of 2019, eleven countries have had the capability to send objects into orbit using their own launch vehicles. Russia and Ukraine inherited the space launchers and satellites capability from the Soviet Union, following its dissolution in 1991.
A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth.
