Tuesday, August 26th, 2008Satellite communications systems (or satcoms as they are referred to in short) help in providing a communication link. This is carried out through artificial satellites which are positioned in different kinds of orbits in space. Satellite communications systems use one or more of these five kinds of orbits – geostationary orbits, low (non-polar and polar) Earth (LEO) orbits, medium earth orbits (MEO), highly elliptical orbits (HEO) and Molniya orbits.
Satellite Communications Equipment
Tuesday, July 1st, 2008Commercial satellite communications equipment solutions are employed by corporations of all sizes and span a vast array of industries. From power, oil, mining, and medical to education, commercial and consumer produce, on-command and reliable satellite communications equipment are more important than ever. The need for reliable satellite Internet, TV and radio services continues to amplify as the need for immediate satellite communications equipment becomes a mainstay of commerce. Constant connections and high speed communications via satellite are requirements.
Satellite Terminals
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.

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:
