Saturday, June 28th, 2008Satellite terminals have changed the way man and communicates and interacts and will continue to advance and change as time goes on. The new millennium has seen an unbelievable growth in terminals that has changed the way man lives and interacts. The use of satellite terminals is one of the biggest contributing factors to this increase in the size of mankind’s communication web.
Satellite Communications Systems
Saturday, June 21st, 2008Commercial satellite communications equipment answers are employed by corporations of all sizes and span a large array of industries. From power, oil, mining, and medical to education, business and consumer wares, on-order and consistent satellite communications equipment are more critical than ever. The need for consistent satellite Internet, TV and radio services continues to enlarge as the need for immediate satellite communications equipment becomes a mainstay of commerce. Constant connections and high speed communications via satellite are necessities.
Satellite Orbits
Thursday, June 19th, 2008A Dish Network satellite TV system is based off signals transmitted and received by multiple satellites. But, the main satellites in space are constantly moving in what is called an orbit.
Any object that moves around the earth has an orbit. The orbit is defined by 3 factors. The first is the shape of the orbit, which can be circular or elliptical. The second is the altitude of the orbit. The altitude is constant for a circular orbit but changes constantly for an elliptical orbit. The third factor is the angle the orbit makes with the equator. An orbit that brings the satellite over the poles or close to it has a large angle. An orbit that makes the satellite stay close to the equator has a small angle. Orbits depend on the mission the satellite was built for. The following orbits can be defined:
Satellite Communication Security
Friday, April 11th, 2008by K Anand
Communications Intelligence (COMINT) involving the covert interception of foreign communications has been practiced by almost every advanced nation since international telecommunications became available. COMINT is a large-scale industrial activity providing consumers with intelligence on diplomatic, economic and scientific developments.
Various communication intelligence equipments have been and are been designed in order to provide all with a secure communication channel. As satellite communications is growing day by day and is taking the major seat in the global communication network, products are being designed keeping the Security issue in mind.
Satellite Wireless Communications
Thursday, March 13th, 2008Satellite wireless communications are also simply known as satellite communications (which is also abbreviated as satcom). Satellite wireless communications are carried out through artificial satellites positioned in space in different kinds of orbits. There are five different kinds of orbits. These are low (non-polar and polar) Earth (LEO) orbits, medium earth orbits (MEO), highly elliptical orbits (HEO), Molniya orbits and geostationary orbits.
