Satellite Communications Training for non-engineers

Technical Aspects of Satellite Communications Training for non-Engineers

Satellites are relay stations in space for the transmission of voice, video and data communications.

They are ideally suited to meet the global communications requirements of military, government and commercial organizations because they provide economical, scalable and highly reliable transmission services that easily reach multiple sites over vast geographic areas.

Transmissions via satellite communications systems can bypass the existing ground-based infrastructure, which is often limited and unreliable in many parts of the world.

Satellite communications involves four steps:

  1. An uplink Earth station or other ground equipment transmits the desired signal to the satellite
  2. The satellite amplifies the incoming signal and changes the frequency
  3. The satellite transmits the signal back to Earth
  4. The ground equipment receives the signal

The next era of satellite communications is upon us in the form of low-earth-orbit constellations aiming to revolutionize personal connectivity.

At least that’s what the satellite experts say. These new satellite swarms are being driven by technology innovations simultaneously with the growth of less-expensive launch services. This is expected to result in a mushrooming explosion in the number and type of orbiters serving their earthbound hosts while raising the bar for support technologies on the ground.

Consequently, given the overall satellite communications (SATCOM) field becoming more dynamic, companies are compelled to be more flexible as uncertainties increase. Some, you could say, are hedging their bets and exploring the use of orbiters that can be replaced or upgraded relatively easily, as opposed to complex and expensive platforms that last many years but take just as long to design and, if necessary, replace.

What’s happening as a result is a spurt in the number of low-earth-orbit satellites that introduce new capabilities for SATCOM services. Their constellations in turn will spawn innovative technologies that can be applied both on orbit and on the ground.

It’s expected that both the military and the private sector soon will have at their disposal large constellations of communications satellites offering a variety of capabilities.
