As a service to the CelesTrak user community, users with valid
Space Track accounts (accounts may be obtained at www.space-track.org) may access this
page to receive data in the formats they are already accustomed to. This
access will simply format queries to the Space Track system and return them as
provided by Space Track.
Limitations: Currently, there are several limitations
with this approach:
- While these queries do provide the same data, some queries can take a
minute or more to return (results may improve with more frequent access).
Update: Space Track has dramatically improved query performance and
all results are returned virtually instantaneously.
- Due to limits on the number of objects returned per query (100), some data
sets had to be broken into several parts. Update: Space Track has taken
action to allow longer queries, but limitations on URL length seem to prevent
taking advantage of this capability. It does not appear to be a Space Track
- There is a two-line header (Object ID Query Results) at the top of each
page. Update: The two-line header has now been removed.
- Object names are those used by Space Track, not those used in the standard
CelesTrak data sets and the name field is not a fixed 24-character
- Due to security restrictions in the standard Document Object Model
incorporated in most web browsers, there is no way to filter the data to check
for data quality or standard formatting.
Given these limitations, you may still have problems loading
this data into existing satellite tracking applications.
New: A standalone Windows
application is now available which eliminates all of these issues and
allows Space Track users to generate standard CelesTrak data sets easily and
quickly on their own system.
