ABSTRACT
Satellite crosslinks generally require narrower bandwidths for increased power concentration. We can increase the power concentration by increasing the cross page link frequency with the same size antenna. But the source technology and the modulation hardware required at these higher frequency bands are still in the development stage. Use of optical frequencies will help to overcome this problem with the availability of feasible light sources and the existence of efficient optical modulation communications links with optical beams are presently being given serious considerations in intersatellite links and establishing an optical cross page link requires first the initial acquisition and cracking of the veacon by the transmitting satellite followed by a pointing of the LASER beam after which data can be modulated and transmitted.
