Basic Examples (4) 

Retrieve the two line elements (TLE) using the NORAD number of a satellite:

In[1]:=

Out[1]=

The NORAD number can be specified as a string:

In[2]:=

Out[2]=

Retrieve the two line elements (TLE) using the entity representation of a satellite:

In[3]:=

Out[3]=

Retrieve the two line elements (TLE) using the name of a satellite:

In[4]:=

Out[4]=

Scope (2) 

A list of specifications can be provided to get back a list of TLEs:

In[5]:=

Out[5]=

Return a list of valid groups of satellites that can be queried:

In[6]:=

Out[6]=

A list of TLEs can be returned for satellite groups:

In[7]:=

Out[7]=

Properties and Relations (1) 

ImportString can be used to parse the results of CelesTrakTLE into a list of rules:

In[8]:=

Out[8]=

Possible Issues (2) 

Some satellites may not have TLEs available:

In[9]:=

Out[9]=

This is because CelesTrak doesn't track "space junk", such as rocket bodies and debris:

In[10]:=

Out[10]=
