The United States currently operates the most capable SSA system, the Space Surveillance Network (SSN). The SSN is composed of stations based around the globe that use a combination of radar and optical information to track objects in orbit. The system has impressive abilities; it is able to detect objects the size of a basketball at an altitude of ## kilometers (## miles), and smaller objects closer to Earth.

Country: Spain
During 2016, European companies noted and seized opportunities within the business of space situational awareness (SSA). Europe’s continued growing dependence on services provided by an orbiting space infrastructure and desire for high-resolution European-based SSA data are presenting openings...

Country: Russia, United States
The Russian Space Surveillance System (RSSS) consists of a network of ground-based radars and optical telescopes, operated by the Russian Defense Ministry’s Space Control Center (TSKKP), which is responsible for the nation’s space situational awareness (SSA). The RSSS sensors give the nation...
Year: 2016
As more European-made satellites are launched into Earth’s orbit, more Europeans are realizing the importance of space traffic management (STM) and space situational awareness (SSA). The European Space Agency (ESA) continued to fund its own SSA program through 2016, which involves...

Country: United States
With increased demands for space traffic management (STM) and space situational awareness (SSA), commercial companies, such as Schafer Corporation, formed businesses during 2016 to meet the demand. These commercial STM and SSA providers are building their own space object catalogs and using...
Year: 2015
The European Space Agency is funding its own SSA program, mandated in 2008, launched in 2009, and funded through 2016. Europe’s increasing dependence on space-based services and infrastructure was a key factor in developing alternatives to non-European SSA sources. ESA’s SSA activities involve...

Country: France
SSA operations in France are shared by the French Air Force and the Centre National d’Études Spatiales (CNES). The missions for French SSA activities are similar to U.S. military efforts, attempting to catalog all low Earth orbiting objects for collision and launch avoidance. The French do use...
Year: 2015
Collision avoidance is gaining the attention of commercial satellite operators as the Earth’s orbits continue to become more congested. A non-profit association of satellite operators from the Isle of Man, the Space Data Association, offers conjunction assessment services to its members. The...

Country: United States
Since July 2010, the United States Strategic Command’s Joint Space Operations Center (JSpOC) has collected satellite orbit data and provided SSA to military, government, and commercial satellite operators through sending out predictions of close approaches for operational satellites. In October...

Country: United States
U.S.-based companies like Analytical Graphics, Inc. (AGI) are developing their own SSA initiatives. Supplying services based more on the USSTRATCOM vision of SSA to space operators, commercial SSA services, processes and teams offer an alternative to JSpOC. Although the notifications from the JSpOC...
