Definition

1. Adjective:
   • Relating to or having a geosynchronous orbit with a fixed position relative to the Earth's surface: Describes an object, typically an artificial satellite, that orbits the Earth at the same rotational speed as the planet, allowing it to remain constantly above the same geographic point on the equator.

Usage Examples

• Adjective:
  • Communication signals are often relayed by a geostationary satellite.
  • The weather monitoring system relies on data from a geostationary platform.
  • To maintain a geostationary orbit, the satellite must be positioned at a very specific altitude.

Advanced Usage

• "Geostationary orbit": The specific circular orbit approximately 35,786 kilometers (22,236 miles) above the Earth's equator where a satellite's orbital period matches the Earth's rotation period.

  • Placing a satellite into geostationary orbit requires precise calculations and propulsion.

• "Geostationary operational environmental satellite (GOES)": A specific series of satellites used for weather observation.

  • The GOES network provides continuous imagery and atmospheric measurements of the Western Hemisphere.

Variants and Related Words

• Geosynchronous (adjective): Having an orbital period equal to the Earth's rotational period. (Note: A geostationary orbit is a special type of geosynchronous orbit that is circular and equatorial, resulting in a fixed position.)
• Geostationary Satellite (noun phrase): A satellite in a geostationary orbit.

Synonyms

• Geosynchronous (in the specific context of a fixed equatorial position): Orbiting in sync with Earth's rotation.

Antonyms

• Non-geostationary: Referring to any orbit (e.g., Low Earth Orbit, polar orbit) where the satellite's position relative to the Earth's surface is not fixed.
• Sub-synchronous: Having an orbital period less than the Earth's rotational period.

Adjective

1. of or having a geosynchronous orbit such that the position in such an orbit is fixed with respect to the earth
   • a geostationary satellite
