Telstar 1 was only one of the many satellites tracked by the Grand Turk station and may have been chosen as a stamp design for this set as it was the first instantaneous relay communications satellite.

Interplanetary satellites that fly toward planets such as Jupiter and Saturn are so far away from the sun that they cannot use solar panels to generate electricity.
Remote sensing satellites are low height satellites which revolve round the earth at a high speed and thus scans the total earth surface once in a single repetitive period.
There are up to 24 satellites in six different orbits equispaced around the equator, which have been described as being reminiscent of a spherical birdcage.

Navtrak utilizes GPS satellites to communicate vehicle speed and position to small boxes called mobile managers which are installed in your vehicles.
Today, satellites are used by the major television networks to distribute regular programming to affiliates and to transmit special events.
Satellites deployed to provide video carriage for cable companies also operate as direct video broadcasters for consumers who own backyard dishes.

These satellites utilize thruster rockets to remain in or change their orbits due to a variety of factors including the influence of gravitational forces exerted by the earth.
Satellites orbiting above the Earth's atmosphere had been used to measure the amount of dust in space, and on this basis it had been estimated that there would be a layer of dust about 1.
For tracking satellites I prefer the telephoto lens as it gives a useful field of view and since satellite predicted positions can vary somewhat from what is predicted the bigger the field of view the better ones chance of seeing the satellite.
