Nilesat
Egyptian Satellites Co SAE or Nilesat (; or , ) is a company and the name of a series of Egyptian communications satellites. It was established in 1996 by the government of Egypt with the purpose of operating Egyptian satellites and their associated mission control center and ground stations. The company is now listed on the Egyptian Exchange, though remains controlled by the government (c.75%) through the National Media Authority (40%), and other state-owned enterprises (SOEs).

Elektro–L
Elektro–L () is a series of meteorological satellites developed for the Russian Federal Space Agency by NPO Lavochkin. The first satellite, Elektro-L No.1, was launched on 2 January 2011. It is the first Russian weather satellite that successfully operates in geostationary orbit, and is currently the second operational Russian weather satellite. The satellites have a mass of about 1620 kg and are designed to operate for 10 years each. They are capable of producing images of the Earth's whole hemisphere in both visible and infrared frequencies, providing data for climate change and ocean m

Syncom (for "synchronous communication satellite") started as a 1961 NASA program for active geosynchronous communication satellites, all of which were developed and manufactured by the Space and Communications division of Hughes Aircraft Company (now the Boeing Satellite Development Center). Syncom 2, launched in 1963, was the world's first geosynchronous communications satellite. Syncom 3, launched in 1964, was the world's first geostationary satellite.

Yaogan satellites
Yaogan () is the designation used by the People's Republic of China to refer to its military reconnaissance satellites. Yaogan satellites are largely known to primarily support the People's Liberation Army's Strategic Support Force (PLASSF), formerly the Aerospace Reconnaissance Bureau of the Second Department of the General Staff. The Yaogan program is the successor to the Fanhui Shi Weixing (FSW) recoverable reconnaissance satellite program but, unlike its predecessor, includes a variety of classes utilizing various means of remote sensing such as optical reconnaissance, synthetic-aperture r

Sentinel-3
Sentinel-3 is an Earth observation heavy satellite series developed by the European Space Agency as part of the Copernicus Programme. As of 2024, it consists of 2 satellites: Sentinel-3A and Sentinel-3B. After initial commissioning, each satellite was handed over to EUMETSAT for the routine operations phase of the mission. Two recurrent satellites, Sentinel-3C and Sentinel-3D, will follow in approximately 2026 and 2028 respectively to ensure continuity of the Sentinel-3 mission.

MetOp
MetOp (Meteorological Operational satellite) is a series of three polar-orbiting meteorological satellites developed by the European Space Agency (ESA) and operated by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). The satellites form the space segment component of the overall EUMETSAT Polar System (EPS), which in turn is the European half of the EUMETSAT / NOAA Initial Joint Polar System (IJPS). The satellites carry a payload comprising 11 scientific instruments and two which support Cospas-Sarsat Search and Rescue services. In order to provide data co

Gaofen () is a series of Chinese high-resolution Earth imaging satellites launched as part of the China High-resolution Earth Observation System (CHEOS) program. CHEOS is a state-sponsored, civilian Earth-observation program used for agricultural, disaster, resource, and environmental monitoring. Proposed in 2006 and approved in 2010, the CHEOS program consists of the Gaofen series of space-based satellites, near-space and airborne systems such as airships and UAVs, ground systems that conduct data receipt, processing, calibration, and taskings, and a system of applications that fuse observati
Jilin 1
Jilin-1 () is China's first self-developed commercial remote sensing satellite system. The satellites are operated by Chang Guang Satellite Technology Corporation and named after Jilin Province where the company is headquartered. The first set of satellites were launched by Long March 2D in Jiuquan Satellite Launch Center on 7 October 2015, at 04:13 UTC. All launched Jilin-1 satellites are in Sun-synchronous orbit (SSO).

Nimiq
The Nimiq satellites are a Canadian fleet of geostationary telecommunications satellites owned by Telesat and used by satellite television providers including Bell Satellite TV and EchoStar (Dish Network). 'Nimiq' is an Inuit word used for an object or a force which binds things together. A contest in 1998 was held to choose the name of these satellites. The contest drew over 36,000 entries. Sheila Rogers, a physiotherapist from Nepean, Ontario, submitted the winning name.

Shijian (, abbr. "SJ") is a series of satellites built and operated by the People's Republic of China. Some Shijian-series satellites have drawn significant concerns from the United States government and space observers who cite unannounced launches, undisclosed sub-satellites deployed in orbit, unusual orbital maneuvers, and demonstrated rendezvous proximity operations (RPO) including the close inspection and towing of other satellites.

SAMOS-F or Air Force Program 102 refers to a series of SIGINT reconnaissance satellites launched and operated by the United States Air Force and National Reconnaissance Office during the 1960s. Initial priorities (in decreasing order) were to monitor radio waves in the frequency bands 2.5-3.2 GHz (S band), 9.0–10 GHz (X band), and 59-650 MHz. The intercepted data and their location were stored on magnetic tape, and subsequently transmitted to tracking and acquisition ground stations. Tracking stations were located in
