The Indian Space Research Organisation is India's national space agency. It serves as the principal research and development arm of the Department of Space (DoS), overseen by the Prime Minister of India, with the Chairman of ISRO also serving as the chief executive of the DoS. It is primarily responsible for space-based operations, space exploration, international space cooperation and the development of related technologies. The agency maintains a constellation of imaging, communication and remote sensing satellites. It operates the GAGAN and IRNSS satellite navigation systems. It has sent three missions to the Moon and one mission to Mars.

FalconSAT is the United States Air Force Academy's (USAFA) small satellite engineering program. Satellites are designed, built, tested, and operated by Academy cadets. The project is administered by the USAFA Space Systems Research Center under the direction of the Department of Astronautics. Most of the cadets who work on the project are pursuing a bachelor of science degree in astronautical engineering, although students from other disciplines join the project.

PROBA, renamed PROBA-1, is a Belgian satellite technology demonstration mission launched atop an Indian Polar Satellite Launch Vehicle by ISRO on 22 October 2001. The satellite was funded through the ESA's MicroSat and General Study Program with the objective of addressing issues regarding on-board operational autonomy of a generic satellite platform. This small boxlike system, with solar panel collectors on its surface, hosts two Earth Observation instruments dubbed CHRIS and HRC. CHRIS is a hyperspectral system that images at 17 m resolution, while HRC is a monochromatic camera that images visible light at 5 m resolution.

Cartosat-2A is an Earth observation satellite in a Sun-synchronous orbit and the third of the Cartosat series of satellites. The satellite is the thirteenth satellite in the Indian Remote Sensing (IRS) satellite series to be built, launched by the Indian Space Research Organisation.

IMS-1 is an Earth observation satellite in a Sun-synchronous orbit. The satellite which is the fourteenth satellite in the Indian Remote Sensing (IRS) satellite series has been built, launched and maintained by the Indian Space Research Organisation (ISRO). IMS-1 is the first satellite to use ISRO's Indian Mini Satellite bus.

The Integrated Space Cell was the nodal agency within the Government of India with oversight of the security of its space based military and civilian hardware systems. It was to be jointly operated by all the three services of the Indian Armed Forces, the civilian Defence Research and Development Organisation and the Indian Space Research Organisation (ISRO). This agency was superseded by Defence Space Agency in 2019.

YouthSat is a Russian-Indian scientific-educational artificial satellite developed on the basis of an agreement between the Russian Federal Space Agency and the Indian Space Research Organisation (ISRO). It is built using ISRO's Indian Mini Satellite-1 bus. YouthSat and Resourcesat-2 were launched by Polar Satellite Launch Vehicle on 20 April 2011 from Sriharikota, India.

This page includes a list of satellite buses, of which multiple similar artificial satellites have been, or are being, built to the same model of structural frame, propulsion, spacecraft power and intra-spacecraft communication. Only commercially available buses are included, thus excluding series-produced proprietary satellites operated only by their makers.

INSAT-2B was the second satellite in the INSAT 2 Series that was successfully launched for telecommunication and meteorological observation. This India satellite was launched on 23 July 1993 from Kourou, French Guiana and Ariane-4 being its launch vehicle. INSAT-2B is placed in the geostationary orbit at a longitude of 93.5 degree East. The satellites also carries a search and rescue(SAR) transponder, a data relay transponder and also high resolution radiometer. This radiometer has a resolution of 2 km (1.2 mi) in the normal visible band and of 8 km (5.0 mi) in the thermal infra red band.
