2011 – BeiDou – Snapshot
Since 2000, China has also been building its own national PNT system, known as Beidou (the Mandarin name for the constellation otherwise known as the Big Dipper). China launched ## satellites in 2011 to join the ## currently in orbit. These satellites will later become part of a global constellation, Compass, which is planned to consist of ## MEO satellites for global coverage and ## GEO satellites that will focus on regional coverage over China. Beidou began operating in December 2011, providing initial PNT services to a swath of the Asia-Pacific region from Australia in the south to Russia in the north with an accuracy of 25 meters (82 feet).
2011 – South African Government Space Budget – Snapshot
Space activities in South Africa are funded through the Department of Science and Technology (DST). In FY 2011, which ran from April 2011 to March 2012, the DST planned to spend ## million rand (US$## million) on space activities executed through two programs: the South African National Space Agency (SANSA) and the Space Science Research, Development and Innovation subprogram. SANSA, established in 2008, planned an FY 2011 budget of ## million rand (US$## million).
2011 – Space Policy: Programs and Progress Snapshot
As space activities across the globe become more dynamic—blending commercial, government, and cross-border activities—governments increasingly see a need for a formal space policy to provide a framework for coordination and integration of activities. Effective space policy can foster public interest… Thank you for visiting The Space Report! The Authoritative Guide to Global Space Activity, Packed…
2011 – U.S. Space Surveillance Network – Snapshot
A series of SSN upgrades are underway. In 2011, a DARPA-funded space surveillance telescope underwent testing. After nine years of development, the new telescope, located at White Sands Missile Range, New Mexico, is capable of capturing wide-field views of objects in GEO orbit. While the SSN uses radar signals to track objects in LEO, distant objects in GEO orbits are tracked by optical systems such as the DARPA telescope at White Sands and other telescopes in Hawaii; Socorro, New Mexico; and the island of Diego Garcia in the Indian Ocean.
2010 – Trends That Are Shaping Space Activity
This Dragon spacecraft orbited the Earth before reentering the atmosphere and landing less than one mile from the center of the landing zone in the Pacific Ocean. This achievement made SpaceX the first commercial company in history to safely return a spacecraft from orbit. Credit: SpaceX/ Mike Alten… Thank you for visiting The Space Report!…
2010 – Satellite Communications – Snapshot
The satellite services sector, which includes fixed and mobile satellite services, registered $## billion in 2010 revenue, up from $## billion in 2009. Both types of services communicate information in video, voice, and data formats. Fixed satellite services (FSS) refer to the delivery of satellite communications to stationary ground receivers that can be moved from one location to another but do not work while in transit. Mobile satellite services provide similar capabilities but the communication link ties to mobile receivers, such as satellite telephones or in-flight communications.
2010 – Bigelow Space Stations – Snapshot
Bigelow Aerospace has been working for several years to develop commercial orbital habitats using expandable modules. This approach, leveraging technology licensed from NASA, involves launching modules in a compact form and inflating them once in orbit, creating much larger volumes than would be possible with traditional metallic structures.
2010 – Degrees Awarded – Snapshot
While mechanisms such as the PISA test reveal a cross-national focus on primary and secondary STEM competency, a more direct measure of the potential international space workforce is offered through a comparative analysis of STEM university graduates by country.
2010 – U.S. Space Surveillance Network – Snapshot
One specialized type of system that uses both satellites and ground stations is dedicated to space situational awareness (SSA). An SSA system tracks satellites and other objects orbiting Earth. This is accomplished through a series of ground stations which are dedicated to scanning the sky via a variety of means in order to detect and plot the courses of objects in space. This data is then compiled and analyzed to create a series of predictions regarding possible collisions.
2010 – Ground Networks – Snapshot
An essential element of space infrastructure, ground stations transmit commands to and receive data from spacecraft. They also often contain facilities to process that data, particularly in the case of Earth observation satellites. The data sent from ground stations includes command and control data, software upgrades, and other mission-critical instructions. Satellites send information such as tracking and telemetry data in addition to imagery and scientific observations.
