2005 – Orbital Launch Reports and Forecasts
The FAA’s Office of Commercial Space Transportation (FAA/AST) and the Commercial Space Transportation Advisory Committee (COMSTAC) prepare an annual forecast of international demand for commercial launch services. COMSTAC assesses demand for geosynchronous orbit (GEO) launches, and the FAA predicts demand for non-geosynchronous (NGSO) launches.
2005 – ICBMs and SLBMs
Intercontinental ballistic missiles (ICBM) and submarine-launched ballistic missiles (SLBM) fly a ballistic trajectory, normally intended to carry a nuclear warhead as a payload. While they do not orbit the Earth, the apogee of their flight brings them to altitudes at and well above LEO.
2005 – Communications Satellites Overview
Currently, the Satellite Database maintained by Analytical Graphics, Inc. (AGI) shows that 536 active communications satellites are in orbit. Of these, 298 are in a geostationary (GSO) or geosynchronous (GEO) orbit.1Teal Group Corporation projects a total of 176 GEO commercial satellites worth … This article is for subscribers.

2005 – Human Settlements
Surface systems are those systems that operate on the surface of a planet. Current operational surface systems include the NASA Jet Propulsion Laboratory (JPL) Mars Rovers, Spirit and Opportunity. These robots were launched in June and July 2003, with the purpose of understanding the history of water on Mars.
2005 – Bigelow Space Stations
A privately financed company based in Las Vegas, Nevada, Bigelow Aerospace is licensing technology from NASA to build an inflatable in-space platform that could enable a number of on-orbit applications. Bigelow’s prototype inflatable platform was launched July 12, 2006, aboard a Russian- and Ukrainian-built Dnepr rocket, launched from Russia’s Yasny Launch Base by International Space Company (ISC) Kosmotras.
2005 – ISS
The largest in-space platform ever constructed is the International Space Station (ISS). “Led by the United States, the ISS draws upon the scientific and technological resources of 16 nations: Canada, Japan, Russia, 11 nations of the European Space Agency [Belgium, Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, Switzerland, and the United Kingdom], and Brazil,” according to NASA.
2005 – QZSS
Japan is developing the Quasi-Zenith system, a regional augmentation of the GPS signal, with a 2008 planned launch.
2005 – Galileo
Europe launched the first test satellite in the Galileo system in December 2005.
2005 – GPS
The U.S. NAVSTAR (Navigation Signal Timing and Ranging) GPS constellation consists of ## active and ## spare satellites in MEO. According to the DoD, the fundamental concept of GPS is to use simultaneous distance measurements from ## satellites to compute the position and time of any receiver. The GPS signal is available without cost to users around the world and has spawned many commercial applications.
2005 – Ground Networks
Ground station infrastructure provides command, control, tracking, and telemetry systems for launch vehicles, satellites, and other platforms. Worldwide tracking systems operated by government agencies support launch command and control. Satellite ground stations are operated either by commercial or government entities; their components include the large satellite receivers used to transmit and receive signals to and from satellites on orbit for the purpose of communication, navigation, or data transfer.
