Aviation Edge Satellite Tracking API with Two-line Element Set

Two-line element set is a widely used format that is also used by the leading astronautics organizations such as NORAD and NASA. Developers in the field are finding it convenient to conduct satellite tracking with two-line element set. But what do the two-line element sets include? To clarify, it consists of two lines which each has 69 characters. These characters are in fact data in a specific order that specifies the position and velocity of a satellite.

Satellites tracking with two-line element set is only possible for satellites that have publicly available data. In most cases, these are specified as “U” in classification which stands for “Unclassified”. There are also satellites with “secret data” which can be shown by an “S” as the classification value. But needless to say, data on these are generally not publicly available. An example for these satellites would be the ones that collect and send data regarding national security.
