A journal or diary
Software that calculates the apparent position of celestial bodies
A table giving the apparent position of celestial bodies throughout the year; normally given as right ascension and declination
Table of the positions of celestial bodies at regular intervals, often with supplementary information. Constructed as early as the 4th century BC, ephemerides are still essential to astronomers and navigators. Modern ephemerides are calculated, with heavy computing and careful checking, after a mathematical description of a heavenly body's observed motion has been evolved. Various national ephemerides are published regularly; the U.S. ephemeris, first published in 1852, became the best and is now published jointly with the U.K. as The Astronomical Almanac
{n} a daily account of the planetary motions
A book containing tables listing the location of the planets on a given day at a certain time, usually noon GMT
A list of (accurate) positions or locations of a celestial object as a function of time Available as "broadcast ephemeris" or as preprocessed "precise ephemeris "
A table listing the positions of the planets and nodes and usually including other astronomical data
A list of accurate positions or locations of a celestial object as a function of time Available as "broadcast ephemeris " or as post-processed "precise ephemeris "
A publication giving the computed places of the heavenly bodies for each day of the year, with other numerical data, for the use of the astronomer and navigator; an astronomical almanac; as, the "American Ephemeris and Nautical Almanac
an annual publication containing astronomical tables that give the positions of the celestial bodies throughout the year; "today computers calculate the ephemerides
A table that gives the computed position of a celestial body, such as a planet, at certain times Positions from an ephemeris can be plotted onto a sky map to show where a moving object can be found at a given time Sometimes other information, such as magnitude, may also be provided
Pronounced ee-FEM-er-is (ef-fi-MARE-uh-deez) A table listing specific data of a moving object, as a function of time Ephemerides usually contain right ascension ("R A " in these web pages) and declination ("Decl " in these web pages), apparent angle of elongation ("Elong " in these web pages) from the sun (in degrees), and magnitude (brightness) of the object; other quantities frequently included in ephemerides include the objects distances from the sun and earth (in AU), usually given as Roman letter "r" and Greek letter "Delta", respectively; phase angle; and moon phase
Pronounced ee-FEM-er-is, ef-fi-MARE-uh-deez A table listing specific data of a moving object, as a function of time Ephemerides usually contain right ascension and declination, apparent angle of elongation from the sun (in degrees), and magnitude (brightness) of the object; other quantities frequently included in ephemerides include the objects distances from the sun and earth (in AU), phase angle, and moon phase
An Ephemeris is a position of an object at a particular time, or a list of such positions Frequently, other time-dependent information is included, like the Apparent Visual Magnitude, and derivatives of the position For radar astronomy, the position must include the range and the Doppler shift of the object, as well as the more usual astronomical Right Ascension and Declination, because the receivers must be tuned to the correct frequency to be able to detect the echo
Time obtained from observing the motion of the moon around the earth
A table of data arranged by date Ephemeris tables are typically to list the positions of the Sun, Moon, planets and other solar system objects
A list of accurate positions or locations of a celestial object as a function of time Available as "broadcast ephemeris" or as postprocessed "precise ephemeris "
{i} astronomical calendar (shows the approximate position of the sun, moon and stars in the sky during a given year)
Information relating to the orbital paths of satellites The position of an astronomical body
A book which supplies the positions of the Sun, Moon and planets, usually daily Positions are generally given in celestial longitude, latitude and declination Other information (i e , sidereal time, the nodes of the Moon, ingresses) may also be supplied Positions are usually given at either noon or midnight, for Greenwich, England
A diary; a journal
A book of tables showing the zodiac position of each planet every day of the year It may look boring, but it's one of the most fascinating books in the world See also the Online Ephemeris
A collective name for reviews, magazines, and all kinds of periodical literature
A tabulation of a series of points that define the position and motion of a satellite See Keplerian elements
" Any tabular statement of the assigned places of a heavenly body, as a planet or comet, on several successive days
an arrangement of a series of data points defining both the position and motion of a satellite
The predictions of current satellite positions that are transmitted to the user in the data message
Ephemeris is a set of parameters used by a global navigation satellite receiver to predict the location of a satellite and its clock behavior Each satellite contains and transmits ephemeris data about its own orbit and clock Ephemeris data is more accurate than the almanac data but is applicable over a short time frame from four to six hours Ephemeris data is transmitted by the satellite every 30 seconds See: Almanac
Any tabular statement of the assigned places of a heavenly body, as a planet or comet, on several successive days
Ephemeris (plural: ephemerides) Pronounced ee-FEM-er-is A table listing specific data of a moving object, as a function of time Ephemerides usually contain right ascension and declination, apparent angle of elongation from the sun (in degrees), and magnitude (brightness) of the object; other quantities frequently included in ephemerides include the objects distances from the sun and earth (in AU), phase angle, and moon phase
A periodical publication tabulating the predicted positions of celestial bodies at regular intervals, such as daily, and containing other data of interest to astronomers
A table of predicted satellite orbital locations for specific time intervals The ephemeris data help to characterize the conditions under which remotely sensed data are collected and are commonly used to correct the sensor data prior to analysis
A set of parameters used by a receiver to calculate the location of a navigation satellite and its clock behavior Each navigation satellite transmits ephemeris data about its own orbit and clock Ephemeris data is more accurate than almanac data It is typically good for only 4-6 hours Ephemeris data is transmitted by the satellite every 30 seconds The plural of ephemeris is ephemerides (See Almanac)
The predictions of current satellite position that are transmitted to the user in the data message
a table of data arranged by date; typically tables of the positions of the Sun, Moon, planets and other solar system objects
