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.

Did You Know?

Two-line element sets can only include the following characters:

  • Numbers from 0 to 9
  • Letters from A to Z, all in capital
  • Periods and spaces
  • Plus and minus signs

The Data You Can Find In a Two-Line Element Set

It goes without saying that the data consists of two lines. Below, you may read a very brief explanation of the values you see in a two-line element set.

For more information and any questions about satellite tracking with two-line element set, don’t hesitate to contact our team!

The first line includes the following, in order:

  • Line number (the format of the line
  • The number of the satellite
  • Classification of the satellite
  • International designator code (last two digit and then the launch number of the launch year, followed by the piece of the launch)
  • Epoch time
  • Mean motion
  • BSTAR value
  • Ephemeris type
  • Element number
  • Modulo-10 checksum of the data on line 1 of the element set

For the second line, the pieces of data go in this order, again briefly:

  • Line number (the format of the line)
  • The number of the satelliteInclination
  • Right ascension
  • Eccentricity values
  • PerigeeMean anomaly
  • Mean motion
  • Epoch time (rev. number)
  • Modulo-10 checksum of the data on line 1 of the element set

API Key for Satellite Tracking API with Two-line Element Set

As seen, the lines are a unified set of data that allows satellite tracking with two-line element set. Though, our satellite tracking API data is not limited to this but also covers the data in the set in a raw manner. This means that you can filter and use certain parameters to pull data of a certain satellite or a whole group of satellites that share the same value based on the parameter. For example, you can pull satellites.
