Satellite Communications Training

Satellites have now played a vital role in our lives for nearly 60 years.

The applications of satellite communications have grown with technological advances. Common applications today include:

  •  Remote sensing applications
  • Military applications and navigations
  • Weather condition monitoring and forecasting
  • Radio broadcasting and voice communications
  • TV broadcasting

After the world has seen 8,378 satellites launched, there’s a tendency to take them and the services they provide for granted.

You shouldn’t.

Truly understanding satellite communications involves exposure to technical details.

One of those details is a concept known as gain to noise temperature ratio (G/T). This is a crucial figure of merit in the characterization of antenna performance, where G is the antenna gain in decibels at the receive frequency, and T is the equivalent noise temperature of the receiving system in kelvins.

The receiving system noise temperature is the summation of the antenna noise temperature and the RF chain noise temperature from the antenna terminals to the receiver output.

Antenna temperature (Tant) is a parameter that describes how much noise an antenna produces in a given environment. Antenna noise temperature is not the physical temperature of the antenna but rather an expression of the available noise power at the antenna flange.

Another important term to understand is link budget.  A link budget is an accounting of all of the power gains and losses that a communication signal experiences in a telecommunication system.

It accounts for the attenuation of the transmitted signal due to propagation, as well as the antenna gains and feedline and other losses, as well as the amplification of the signal in the receiver or any repeaters it passes through. A link budget is a design aid, calculated during the design of a communication system to determine the received power, to ensure that the information is received intelligibly with an adequate signal-to-noise ratio.

Orbital mechanics is another key area of understanding. Orbital mechanics is the study of the motion of satellites that are present in orbits. Orbital elements are the parameters, which are helpful for describing the orbital motion of satellites. The main orbital elements that define the orbit of earth satellites are:

  • Semi major axis
  • Eccentricity
  • Mean anomaly
  • Argument of perigee
  • Inclination
  • Right ascension of ascending node

External forces also influence a communication satellite’s behavior. A satellite, when it revolves around the earth, it undergoes a pulling force from the earth due to earth’s gravitational force. This force is known as Centripetal force (F1) because this force brings the satellite toward it.
