In 1977, SATS opened an airfreight terminal at Paya Lebar Airport capable of handling 160,000 tonnes of cargo a year.. In 1980, SATS made the move to Singapore's new Changi Airport after investing S$147 million in a new headquarters building, a new inflight catering centre, which at that time was the largest single-building inflight kitchen in the world, and two new airfreight terminals.
The first satellite relayed phone calls were achieved early on in the space age, after the first relay test was conducted by Pioneer 1 and the first broadcast by SCORE in 1958 at the end of the year, after Sputnik I became at the beginning of the year the first satellite in history.
SAT Reading passages draw from three main fields: history, social studies, and science. Each SAT Reading Test always includes: one passage from U.S. or world literature; one passage from either a U.S. founding document or a related text; one passage about economics, psychology, sociology, or another social science; and, two science passages.
The shift to more affordable technology from the 50 ohm impedance cable and N-connectors of the early C-band systems to the cheaper 75 ohm technology and F-connectors allowed the early satellite television receivers to use, what were in reality, modified UHF television tuners which selected the satellite television channel for down conversion ...
In the late nineteenth century, elite colleges and universities had their own entrance exams and they required candidates to travel to the school to take the tests. [10] To better organize matters, the College Board, a consortium of colleges in the northeastern United States, was formed in late 1899 to establish a nationally administered, uniform set of essay tests based on the curricula of ...
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth.
The first commercial VSATs were C band (6 GHz) receive-only systems by Equatorial Communications using spread spectrum technology. More than 30,000 60 cm antenna systems were sold in the early 1980s. Equatorial later developed a C band (4/6 GHz) two-way system using 1 m x 0.5 m antennas and sold about 10,000 units in 1984–85.
The SATS concept emerged from the work of the Advanced General Aviation Transport Experiments (AGATE) Alliance. The AGATE Alliance was a public-private partnership (1994-2001), established by NASA, between government and industry to revitalize the technology deployment capacity for the U.S. General Aviation industry.
