Military Communication

The world of communication made the world as a global villege. Most of the communication developed for the purpose of Military usage in the world war 2. The advanced radio design development & production in frequency from 1.5 mhz to 5 Ghz. It features high speed built in crypto algorithm. Cryptology is the study of military codes. Written in theirion military codes and electronic counter measure techniques.
1) Frequency hopping
2) Direct response

For reliable communication under severe battle environment. Quality modems to serve the increasing demand for command, communication, control, computer, intelligence, survelliance and reconnaisance. (C4ISR). Multichannel line of sight frequency hopping wide band radio equipment. for reliable inter command parts communication.

Tactical Terminals- Computers & communication controllers from HQ to any point in the battle space.

Chandrayan Of India

Although Moon was explored in the 1969 by the Americans it is very much less we learnt about the Moon. Moon is a very mysterious place for scientists. It is Indians turn to explore the moon. Indians are launching polar satellite launch vehicle into the orbit. Polar orbit is 800 to 1500 kms from the earth. Indians are launching unmanned mission into the PSLV orbit. launching depends on the exact positioning of the earth sun & the moon. Indians wants to explore the poles of the moon.  Polar region of the moon is a mysterious place of atmosphere. Helium gas & gravitational forces need to be studied properly. The space craft is tested on space simulator.
1) Vibration test – before launching the space craft to the moon vibration test carried out on spacecraft. Space shuttle should with stand the 16 tonnes of vibration.

2) Space shuttle should tolerate a noise similar to noise produced by 10 jet engines.

3) Temperature test – It should withstand the temperature of 100′c

Space shuttle should map systematically topography of the moon and chemical 7 micrological mapping of moon to understand the process of formulation & chemical evolution of moon.
