(b) Optical Inter orbit Communications Engineering Test Satellite (OICETS)

2. Optical Inter orbit Communications Engineering Test Satellite (OICETS)

Orbital debris trailing will entirely negate a photometric observation when debris cross the narrow photometric field.

It achieves this by rotating LEDs about two axes.

It consists of two pairs of satellites, one known as quot eccentric quot , inserted in a high apogee orbit (200,000 km) and the other known as quot auroral quot , inserted in a lower apogee orbit (20,000 km).

The Optical Inter Orbit Communications Engineering Test Satellite will be launched into low Earth orbit aboard a J 1 rocket in the middle of 1998 to conduct, in cooperation with ESA, on orbit demonstrations of pointing, acquisition and tracking technology and other key technological elements for optical interorbit communications, which will be important for future space activities.

Typically, radar measurements have been used for space debris in low Earth orbit (LEO), while optical measurements have been used for high Earth orbit (HEO).

Some measurement of small debris in LEO have been done using optical telescopes, but in general, radars outperform telescopes for measurements in LEO.

The United States Space Command employs 1 metre aperture telescopes fitted with intensified vidicon detectors to track HEO objects.

More than 2,500 frames in both visible and infrared bands for identification of landmarks and altitude and orbit refinement were obtained. The orbital mass of the Rohini satellites was about 42 kg.

. Spaceborne laser systems could also play an important role in the area of inter satellite and inter orbit communications.

A Russian Federation Ekran satellite in GSO was observed to explode in 1978.

In the geostationary orbit (GSO) region, space debris observations are made by the ground based optical facilities of the Russian Academy of Sciences.

A Russian Ekran satellite in GEO was observed to explode in 1978.

OICETS will be launched into low Earth orbit aboard the J 1 launch vehicle in the middle of 2000 to conduct on orbit demonstrations of pointing, acquisition and tracking technology and other key technological elements for optical communications.

The eccentric pair were successfully launched in August 1995 and the two auroral satellites were also launched successfully in August 1996 by a Russian Molniya launcher.

OICETS will be launched into low Earth orbit carried by the J 1 launch vehicle in the middle of 2000 to conduct on orbit demonstrations of pointing, acquiring, and tracking technologies and other key technological elements for optical communications.

Whosoever desires honour (should remember) that all honour is with God. All good words ascend to Him, and all good deeds He exalts. As for those who are plotting evil, there is severe punishment for them, and their plots will be fruitless.

Whoever desires honour therefore all honour belongs to Allah! Towards Him only ascends the pure good speech, and He raises high the pious deed and for those who conspire evil is a severe punishment and their own conspiracy will be destroyed. (It is Allah Who bestows honour, to whomever He wills.)

Whosoever desires glory, the glory altogether belongs to God. To Him good words go up, and the righteous deed He uplifts it but those who devise evil deeds theirs shall be a terrible chastisement, and their devising shall come to naught.

Whosoever desireth glory, then all glory is Allah's unto Him mount up the goodly words and the righteous works exalteth it. And those who plot evils, theirs shall be a torment severe and the plotting of those! it shall perish.

Whosoever desires honour, power and glory then to Allah belong all honour, power and glory and one can get honour, power and glory only by obeying and worshipping Allah (Alone) . To Him ascend (all) the goodly words, and the righteous deeds exalt it (the goodly words i.e. the goodly words are not accepted by Allah unless and until they are followed by good deeds), but those who plot evils, theirs will be severe torment. And the plotting of such will perish.

Whoever desires honor all honor belongs to God. To Him ascends speech that is pure, and He elevates righteous conduct. As for those who plot evil, a terrible punishment awaits them, and the planning of these will fail.

He who seeks glory, let him know that all glory belongs to Allah alone. To Him do good words go up, and righteous action uplifts them. But those who contrive evil deeds, a severe punishment lies in store for them, and their contriving will come to naught.

Whoso desireth power (should know that) all power belongeth to Allah. Unto Him good words ascend, and the pious deed doth He exalt but those who plot iniquities, theirs will be an awful doom and the plotting of such (folk) will come to naught.

Whoever seeks honour should know that honour entirely belongs to Allah. To Him ascends the good word, and He elevates righteous conduct as for those who devise evil schemes, there is a severe punishment for them, and their plotting shall come to naught.

He who wants might, the Might belongs to Allah altogether. To Him ascend good words, and the righteous deed He raises. But those who devise evil deeds theirs shall be a terrible punishment, and their plotting shall be annulled.

Whoever desires honor through power then to Allah belongs all honor. To Him ascends good speech, and righteous work raises it. But they who plot evil deeds will have a severe punishment, and the plotting of those it will perish.

Whoever seeks honor should know that all honor belongs to God. Good words (worship) will be presented before Him and He will accept good deeds. Those who make evil plans will suffer intense torment. Their evil plans are doomed to destruction.

Whoever desires honor, then to Allah belongs the honor wholly. To Him do ascend the good words and the good deeds, lift them up, and (as for) those who plan evil deeds, they shall have a severe chastisement and (as for) their plan, it shall perish.

If anyone seeks glory, let him know that glory belongs to God alone. Good words ascend to Him and righteous deeds are exalted by Him. Those who plot evil deeds shall be sternly punished and their plotting will come to nothing.

If any do seek for glory and power, to Allah belong all glory and power. To Him mount up (all) Words of Purity It is He Who exalts each Deed of Righteousness. Those that lay Plots of Evil, for them is a Penalty terrible and the plotting of such will be void (of result).

The mission INTERBALL consists of two pairs of satellites, one in a fairly low orbit (Auroral Probe, apogee 20,000 km) and the other with an apogee of 200,000 km (Tail Probe). These two very different orbits were chosen in order to cover the auroral and the tail region of the Earth apos s magnetosphere, respectively.

And that was that the gravitational field, due to mass, will deflect not only the trajectory of particles, but will deflect light itself.

The international satellite project INTERBALL comprises two large satellites, one in a fairly low orbit (Tail Probe), whereas the other is in a highly eccentric one (Aurora Probe) see also activities of the Space Research Institute Graz.

With the use of ground based optical and radar surveillance systems around the world, space objects with diameters larger than 10 cm in LEO and larger than 1 m in GEO can be observed and tracked.

In this example, each electrical impulse, each deflection on the trace, is caused by a brief pulse of light.

Based on the orbital experience of TUBSAT A and TUBSAT B, launched in 1991 and 1994, respectively, instrumentation of the third spacecraft will also include three fibre optic laser gyroscopes.

These are time in orbit, projected area, orbital altitude and orbital inclination.

On an average adjusted day, a solar cell because the sun's moving across the sky, the solar cell is going down with a sine wave function of performance at the off axis angles.

Small changes in Earth's orbit that occur over tens to hundreds of thousands of years alter the distribution of sunlight on Earth.
