Import and plot the trajectories of all satellites represented in a sample file:

ListPointPlot3D[ Import[ "ExampleData/ephg12913.sp3.gz" ], Boxed-> False, Axes-> None, ImageSize-> Medium]

Import and show the trajectory of a single satellite:

ListPointPlot3D[ Import[ "ExampleData/ephg12913.sp3.gz" ][[1]], Boxed-> False, Axes-> None]

Get the list of available (RefLink[Import, paclet:ref/Import]) formats:

Import[ "ExampleData/ephg12913.sp3.gz" , "Elements"]

Import all position data from the file:

pos=Import["ExampleData/ephg12913.sp3.gz","Positions"];

The resulting array represents the spatial positions of 29 satellites at 144 different times:

Dimensions[pos]

This shows the orbits of all 29 satellites around the Earth:

Show[Graphics3D[{Blue,Sphere[{0,0,0},6378.14`]}],
ListPointPlot3D[pos, PlotStyle-> ColorData[3, "ColorList"] ], Boxed-> False, ImageSize-> Medium]
