Satellite Orbital Elements Database

Finding and loading satellite elements.

Satellite orbital elements database.

Jpl 20 heliocentric ecliptic j2000. Beware that the two line element tle format is very rigid. An index showing the composition of each two line element set data file all data is contained in the files above use it to find which file s you need to download. Look to amsat bb twitter and facebook for the latest information.

Space debris junk trash is the collection of defunct man made objects in space like old satellites spent rocket stages and fragments from disintegration. Now all the orbital elements in the satellite catalog satcat are available in the tle class. In general it takes at least six parameters to uniquely define an orbit and a satellite s position within the orbit. You can find satellite element sets at the norad two line element sets page of the celestrak web site.

The index includes information on age of each element set. 650 x 3832 km. According to nasa more than 500 000 pieces of orbital debris as big as a marble or larger are tracked as they orbit the earth. Every elset already displays a value for the object s mean motion n and eccentricity e so we derive these additional four values using the following calculations.

We provide this data as either keplerian osculating or mean element sets which include the two line and amsat formats. Apogee may not match exactly. In this section let us discuss about the equations which are related to orbital motion. The ground track of a satellite can take a number of different forms depending on the values of the orbital elements.

This file is updated thursday evenings around 2300 utc or more frequently if new high interest satellites are. 554 x 2937 km. The trajectory data which describes the motion of a satellite can take on a variety of formats. However the value of the same element e g.

More than 20 000 of these are larger than a softball. When a new satellite is launched there is some confusion regarding tles. This index also includes links describing many satellite payloads. Forces acting on.

Orbital status designation name in spacetrack catalog orbit. Bulletin format elements for all satellites of interest to radio amateurs. Orbital elements at epoch 2459042 5 2020 jul 12 0 tdb reference.
