NEXEYA Systems is dedicated to the development of ground test tools: test means, space harness and structures. NEXEYA intervenes on all types of programs : civil, miltary, observation, scientific, intrumentation, etc.

• execution of full and rigorous test campaigns before launching to ensure perfect satellite operation in space (afterwards it's too late). 
• designing, making and testing "power/control-command" harnesses for the space flight and ground segment.
• management of complete projects with high responsibility as antennas, batteries, platform or payload NIDA structures, PDU equipment, deployment mechanisms, optical instruments.

BLUEsat, an acronym of Basic Low-Earth-orbit University of NSW Experimental satellite, is a digital amateur radio satellite being designed and built solely by students here at the University of NSW.

The satellite is a small cube measuring approximately 260mm on each side, excluding antennae, and weighs around 14kg. Powered by fixed solar panels on each face, it will carry a flight computer, radio transmitters and receivers, a power-control system, battery packs for when its orbit places it in the Earth's shadow, magnets to passively stabilise the satellite and align it with the Earth's magnetic field, and will be controlled via a dedicated communications groundstation here at UNSW. BLUEsat will be placed in an approximately circular orbit at an altitude of around 750km that will take it over the poles. At this altitude, the satellite will travel around the Earth at a rate of around once every 90 minutes.

BLUEsat is primarily an educational satellite, designed to give students at UNSW space experience which they could not obtain elsewhere.

The Australian Centre for Space Engineering Research (ACSER) was launched at the University of New South Wales (UNSW) in November 2010. The centre aims to assist in the Federal Government's push to increase Australia's capabilities in the space industry.

The centre will build on existing UNSW strengths of satellite navigation, earth observation, and hypersonics, and can draw on the huge expertise of Australia's largest Engineering faculty. UNSW is participating in five Australian Space Research Program (ASRP) projects.

Global Satellite Engineering (GSE) was established in 2005 to provide engineering solutions for the satellite industry.

Space Engineering (S.E.) was founded in 1989.

The Company is providing engineering services, characterised by highly technical contents and mainly dealing with satellite systems, space products and services (Antenna Systems, Test Beds, Mission Analysis, Space studies).

SintelSat is a global communications company based in Stony Brook, New York, USA, providing turnkey solutions using Satellite Communication, Fiber, Networking, Microwave Systems and Wi-Fi/ Wi-MAX Wireless technologies.

The company currently serves corporations, local & state government, federal, state, embassies, United Nation, World Bank and many enterprise customers in infrastructure rebuilding, IP connectivity, private networks, VoIP, data and video solutions in emerging markets.

SintelSat has satcom, networking, technical support and NOC capabilities in Afghanistan, Iraq, Lebanon, India, and the Philippines. Field support personnel are available on many continents including Africa, Middle East, Asia and Europe.

The Solar Anomalous and Magnetospheric Particle Explorer (SAMPEX) satellite was launched in July 1992 into a low earth orbit at an altitude of 520 by 670 km and 82 degrees inclination.

The satellite far exceeded its expected three-year lifetime. It has primarily operated in a three-axis stabilized mode but has also been spun for limited periods. The satellite carries four instruments designed to measure the radiation environment of the Earth's magnetosphere.

SAMPEX was an international collaboration between NASA of the United States and Germany. It was part of the Small Explorer program started in 1989.

SAMPEX science mission ended on June 30, 2004.

NASA's PhoneSat project will demonstrate the ability to launch the lowest-cost and easiest to build satellites ever flown in space – capabilities enabled by using off-the-shelf consumer smartphones to build spacecraft.

A small team of engineers working on NASA's PhoneSat at the agency's Ames Research Center at Moffett Field, Calif., aim to rapidly evolve satellite architecture and incorporate the Silicon Valley approach of "release early, release often" to small spacecraft.

The South African National Space Agency (SANSA) is South Africa's government agency responsible for the promotion and development of aeronautics and aerospace space research.

It fosters cooperation in space-related activities and research in space science, seeks to advance scientific engineering through human capital, as well as the peaceful use of outer space, and supports the creation of an environment conducive to the industrial development of space technologies within the framework of national government.

SANSA was established on December 9, 2009 by the National Space Agency Act.
