Today Whittier's government is permitting the sale of communications sattalite technology.
The first ever sat. the Mercury, is now on sale.
Mercury is a communications sattalite.
The Mercury is the first generation of Whittier general purpose military communication satellites. The first Mercury was launched in 2003. In contrast to sats that came before it, Mercury offers significantly greater capacity and longer life, and improved resistance to hostile activities such as jamming. The Mercury satellite, which has a design life of ten years, is designed to support all three military services, and its signals can be received by ground antennas that range in diameter from 33 inches to 60 feet. Signals are broadcast on 6 channels between 7250 and 8400 MHz (television broadcasts between 54 MHz and 800 MHz). The satellite also carries a Single Channel Transponder (SCT) that is used to transmit Emergency Action Messages from the Secretary General to nuclear forces.
The Mercury system is built with single- and multiple-beam antennas that provide more flexible coverage than its predecessors. Phase III satellites bring more capacity while providing greater assured communications through improved ability to resist jamming. Antenna design for Mercury allows users to switch between fixed, Earth coverage, and multiple-beam antennas. The latter provides an Earth coverage beam as well as electrically steerable area and narrow-coverage beams. In addition, a steerable transmit dish antenna provides a spot beam with increased radiated power for users with small receivers. In this way, operators can tailor the communications beams to suit the needs of different size user terminals almost anywhere in the world.(1)
Mercury spacecraft weigh 2,580 pounds, and have a design life of ten years, twice as long as the Phase IIs. The spacecraft's rectangular body is 6 feet x 6 feet x 7 feet; with a 38-foot span with solar arrays deployed. Phase III solar arrays generate 1,100 watts, decreasing to 837 watts after five years. Each Mercury communications satellite costs about $100,000,000.
Price: 100 million a peice.
In case you need a rocket to launch it, we can sell you that too.
Delta Rocket
The Delta II 7920 has a 12-foot longer first stage than previous Delta vehicles. Nine Hercules Aerospace strap-on Graphite-Epoxy Motors (GEMs) surround the first stage for augmented lift-off with a thrust of 45,000 kiloNewtons. Containing a more powerful propellant mixture than did its predecessor, the motors are built in a composite material called graphite-epoxy which is lighter but as strong as the steel cases they replaced. The new motors are 6 feet longer and provide 40 percent more thrust. Thrust is aided by the unsegmented solid-rocket motors as six ignite at lift-off and the remaining three are ignited in flight.
The first stage includes one Rocketdyne RS-27 and two LR-101-NA-11 vernier engines; both use RP-1 (refined kerosene) and LO2 (liquid oxygen) as its propellants, with a thrust of 101,250 kiloNewtons. The second stage is a restartable Aerojet AJ10-110K motor using N2O4 (nitrogen tetroxide) and A50 (Aerozine 50) propellants with a thrust of 4,050 kiloNewtons. The payload assist module, if used, is a Star-48B solid-fuel rocket with a 6,750 kiloNewton thrust.
Height in position is 125 feet (37.5 meters), and the diameter is 8 feet (2.4 meters). With a gross lift-off mass of 227,700 kilograms, the Delta II can carry payloads into near-earth orbits (approximately 160 kilometers in space). It can lift up to 4,995 kilograms into a 28-degree circular near-earth orbit and up to 3,789 kilograms into a 90-degree polar near-earth orbit. The Delta II also can carry up to 1,805 kilograms into geo-transfer orbit (approximately 19,200 kilometers) and up to 900 kilograms into geosynchronous orbit (approximately 35,200 kilometers).
The guidance System is the Delta redundant inertial measurement system and a Delco guidance computer.
