You've probably heard about the asteroid

Apophis is an asteroid that was discovered in 2004.

The ISL in the global satellite projects used microwave radiation as the carrier.

THAICOM 3 is a three axis stabilized satellite spacecraft with a payload of 24 C Band and 14 Ku Band transponders.

(c) Research on and development of intersatellite communications with S band, millimetre wave and optical frequencies using ETS VI

While ERS and Radarsat satellites operate in the C band, JERS 1 operates in the longer L band.

The satellite uses S band for telemetry, command and tracking during its lifetime.

25. Satellite communications

Satellite communication in Poland was limited to fixed satellite service operating in the Ku band and using the geostationary satellites of EUTELSAT, INTELSAT, Dividends from Space (DFS), Kopernikus and ORION F1.

(d) Research on and development of advanced mobile satellite communications using Ka band and millimetre wave and advanced satellite broadcasting using the communications and broadcasting technology satellite (COMETS)

And in 1960, Frank Drake conducted the first SETI observation looking at two stars, Tau Ceti and Epsilon Eridani, for about 150 hours.

Carolyn Porco mentioned another one called Enceladus the other day.

(c) Measure the mass of the asteroid, the ratio of the moments of inertia and the low order harmonics of the gravity field of the asteroid

Those satellites carried instruments that transmitted microwave energy in pulses and measured the travel time of the back scattered microwave signal.

An advanced system of L and S band satellite mobile communications will be developed to provide Ka band and millimetre wave satellite mobile communications systems with demodulator modulator on board satellite switches.

This is the number one high resolution, most precise spectrograph on this planet, called HARPS, which is actually used to detect extrasolar planets and sound waves in the atmospheres of stars.

Also a Hughes HS 601 satellite, PAS 4 can carry more than 320 digital channels transmitted on 16 63 watt Ku band and 16 34 watt C band transponders.

The feeder link between FES and the satellite is in Ku band, while the link between mobile terminals and satellite is in L band.

Planetary scientist Carolyn Porco shows images from the Cassini voyage to Saturn, focusing on its largest moon, Titan, and on frozen Enceladus, which seems to shoot jets of ice.

Professor Van Allen told me about observations of Venus, that there was intense microwave radiation.

The Satellite Communication Centre had been created in Central Poland with satellite earth stations operating with the above mentioned satellite organizations.

Multiplexer, digital VSAT 3.7M C band (redundant)

The auroral zone is the quot mission target quot and the satellite carries energetic particle detectors, magnetic and electric wave experiments, electric field sensors and a UV imager.

Downlink emissions could be particularly damaging and already the emissions of some satellite systems had severely curtailed radio astronomy observations.

Similarly, intersatellite links with similar Ka band satellites would demand switching capabilities.

If anybody here is a fan of the original Star Trek, they ran across an alien ship that had an ion drive, and Spock said,

(f) Research on high data rate satellite communications systems using optical and millimetre wave techniques

I could spit in Potter's eye. I think I will. I think I will.

(b) Planetology, involving the search for planets around stars and stellar occultations in the solar system, the analysis of planets and their satellites and other research.

For future satellite broadcasting services, such as high definition television, integrated service digital broadcasting and provincial satellite broadcasting, a satellite broadcasting system operating in the 21 gigahertz band with a multibeam antenna will be developed.

The auroral zone was the mission target and the satellite carried energetic particle detectors, magnetic and electric wave experiments, electric field sensors and a UV imager.

In fact, Apophis is a blessing in disguise, because it woke us up to the dangers of these things.
