“Despite the strong barriers to entry that prevail in the industry, some daring entrepreneurs are nevertheless attempting to challenge incumbents. The entry of low-cost launchers such as the Space Exploration Technology (SpaceX) Falcon-1 and Falcon-5, offered at USD 6 million and USD 12 million respectively, may…”

Read MoreDirect-to-home (DTH) television is the transmission of television programming directly to end-user equipment. Other terms are direct broadcast and satellite television. The term broadcast service satellite (BSS) is often used…
Read MoreSatellites also provide mobile telephony services. Satellite mobile telephony enables regional to near-global coverage depending on the satellite or constellation, using handsets that communicate directly with a satellite. Mobile satellite telephone service is provided by satellite constellations in LEO, such as Iridium and Globalstar, and by satellites in GEO, such as Inmarsat, Thuraya, and ACeS. These services are provided by satellites primarily using the L-band. Satellites providing mobile phone and data services often are referred to as mobile satellite service (MSS) satellites.
Read MoreSatellites have provided trunking for long-distance telephone service for decades. Most long-distance traffic is now routed over cable, avoiding the lag and other reductions in quality (such as echo) associated with satellite telephone calls. Areas or countries lacking terrestrial backbone still rely on satellite connectivity to the publicly-switched telephone network. Telephone companies or nations lease C-band or Ku-band transponders on GEO satellites. Telephony, along with broadcast television, discussed above, and data services are common FSS applications.

Read MoreThe DoD and national security agencies could also use a variety of Earth observation satellites, like Space Based Infrared System (SBIRS) under development, Fast On-orbit Recording of Transient Events (FORTÉ), and the Multispectral Thermal Imager (MTI) that provide intelligence through a variety of sensors, including multi-spectral imagery, thermal images and event classification, radio burst detectors, and radar imaging.
Read MoreDifferent wavelengths of light are ideal for different sensing activities. For example, radar technology, which uses microwave frequencies, can observe clouds, aerosols, volcanic plumes, sea-surface temperatures, ocean color, vegetation, land cover, snow, ice, fires, and many other phenomena. Visible light and near infrared portions of the spectrum can perceive fine detail and can be used for mineral and soil mapping, precision agriculture, and forestry.
Read MoreSpace Services Inc. of Houston, Texas, offers memorial spaceflights, launching a symbolic portion of a person’s cremated remains into space. These memorials are a small secondary payload on a commercial or scientific satellite launch. Space Services offers Earth return services, Earth orbit services, lunar services, and Voyager (deep space) services.
