User Agreement

The Space-Track.Org website provides access to satellite orbital data
received from Department of Defense (DoD). This is the same data, with
the same latency that has been provided by the NASA Orbital Information
Group (OIG) website for many years. This orbital data consists of
Two-Line Element (TLE) sets, Satellite Catalog Messages, Project Tip
Messages, Satellite Decay Messages, Predicted Decay Forecasts, Satellite
Box Scores, and Satellite Reports.

This website supports both real-time and historical requests for orbital
data. The data is provided to this site at irregular intervals around
the clock (all times on this web site are GMT). Historical data requests
no longer involve human intervention. The data received with the correct
format is placed on the web site in a standard format for easy user
access. TLEs are posted in near real time as updates are received from
the DoD. While the website does no modification of the data presented,
there is no claim or certification of the accuracy of the data.

Note

  • Use of the data obtained from this site is at your sole risk and
    expense. You are solely responsible for the adoption, rejection, use, or
    implementation of the data obtained from this site.
  • The User agrees not to transfer any data or technical information
    received under the agreement, including the analysis of tracking data,
    to any other entity without the express approval of the DoD.
