  • satellites and high-altitude platforms;
  • coverage, region of Earth's surface - visibility from satellite at any given time and ‘track’;
  • orbital motion - motion of man-made satellites around the Earth, following laws of physics;
  • two-body problem, satellite motion and six orbital parameters - the Keplerian elements;
  • geostationary satellite visibility coverage;
  • geostationary satellite, continuous visibility from ground - preferred by communication systems;
  • geodetic model in current use - by GPS, the World Geodetic System 1984 (WGS84);
  • High-Altitude Platforms (HAPs) - a low-altitude quasi-geostationary orbit;
  • Unmanned Aerial Vehicles (UAVs) and NASA Cosmic Ray Energetics And Mass (CREAM) scientific balloon;
  • large tethered aerostat with payload radome
