| geostationary orbit | A geostationary orbit, also referred to as a geosynchronous equatorial orbitGeostationary orbit and Geosynchronous (equatorial) orbit are used somewhat interchangeably in sources., is a circular geosynchronous orbit in altitude above Earth's equator, in radius from Earth's center, and following the direction of Earth's rotation. |
| sidereal daynoun | (astronomy) One day of sidereal time; the time in which Earth rotates once around its axis, relative to the point of the vernal equinox (about 23 hours, 56 minutes, 4 seconds). |
| stellar daynoun | (astronomy) The rotational period of Earth; the time in which Earth rotates exactly 360 degrees around its axis, measured relative to the stars. |
| sun-synchronous orbitnoun | (astrodynamics) A nearly polar orbit in which a satellite passes over the surface of a planet maintaining the same local mean solar time. |
| synchronous orbitnoun | A satellite orbit where the orbital period is equal to, or multiples of, the Earth’s rotational period; i.e. making one, two, three, etc., orbits in a 24-hour period. Examples include geosynchronous (period equals Earth's rotation), semisynchronous (two orbits per day); and geostationary (geosynchronous orbit where satellite maintains a fixed position on the equator). |
| heliocentric orbit | A heliocentric orbit (also called circumsolar orbit) is an orbit around the barycenter of the Solar System, which is usually located within or very near the surface of the Sun. |
| sidereal yearnoun | The orbital period of the Earth with respect to the fixed stars. |
| synodic day | A synodic day (or synodic rotation period or solar day) is the period for a celestial object to rotate once in relation to the star it is orbiting, and is the basis of solar time. |
| diurnal motionnoun | (astronomy) The apparent westward rotation of the celestial sphere, along with the apparent westward revolution of celestial objects, around the celestial poles due to prograde (eastward) rotation of planet Earth relative to the seemingly fixed stars – completed once each sidereal day (about 23 hours, 56 minutes, 4 seconds). |
| tundra orbit | A Tundra orbit is a highly elliptical geosynchronous orbit with a high inclination (approximately 63.4°), an orbital period of one sidereal day, and a typical eccentricity between 0.2 and 0.3. |
| polar orbit | A polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited (usually a planet such as the Earth, but possibly another body such as the Moon or Sun) on each revolution. |
| supersynchronous orbit | A supersynchronous orbit is either an orbit with a period greater than that of a synchronous orbit, or just an orbit whose major axis is larger than that of a synchronous orbit. |
| sidereal timenoun | (astronomy) Time measured by the apparent diurnal motion of the vernal equinox; approximated by that based on the rotation of planet Earth relative to the seemingly fixed stars. |
| solar daynoun | (astronomy) One day of solar time; the time in which a planet such as Earth apparently rotates once around its axis relative to the Sun; the time taken for the Sun to seem to be in the same place in the sky twice (on Earth about 24 hours as an average - the length of solar day is not constant throughout the year) |
| satellite geodesy | geodesy by means of artificial satellites—the measurement of the form and dimensions of Earth, the location of objects on its surface and the figure of the Earth's gravity field by means of artificial satellite techniques. |
| orbitnoun | The curved path of one object around a point or another body. |
| low earth orbitnoun | A satellite orbit around the Earth within an altitude range of approximately 200 to 2,000 km, in which a satellite can communicate with the Earth with minimal time lag and energy consumption. |
| earth's rotation | Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. |
| rotation periodnoun | rotational period |
| yearnoun | The length of a year as marked by a calendar, 365 or 366 days in the Gregorian calendar; a calendar year. |
