I am lookin for a dataset where I can find or calculate the size information of an Earth satellite as described in the seconds page of this paper. It is basically the radius of the smallest sphere which surrounds a satellite. I haven't been able to find a single dataset that provides this information. Does anyone know if such dataset exists? If not are there known websites where I can scrape the information?

Thank you.

JSpOC - now 18th SPCS - uses following values:

  • Payloads and platforms (5meters),
  • rocketbodies and unknownobjects (3meters),
  • debris(1meter)

The catagorisation of each object can be found in the NORAD-SAT-CAT, you can access via Space Track

Another database is the ESA-Discos-DB, which bases on real dimensions and not a catagorisation. But you need to apply for an access!

A good page containing also dimensions of objects is Gunter's space page, but I do not think there is an automatic access...

  • $\begingroup$ Thanks for the answer. Is the current standard calculations made using mentioned classifications? $\endgroup$ – Ege Elgun Aug 30 '20 at 16:00
  • $\begingroup$ @EgeElgun: There are no (largely accepted) "current standard calculations". But as far the calculations are concerned 18th SPCS is sharing, yes they use the classifications. $\endgroup$ – CallMeTom Aug 31 '20 at 4:56
  • $\begingroup$ And yes: this results in putting 5m for every 10cm CubeSat $\endgroup$ – CallMeTom Aug 31 '20 at 4:58

Jonathan McDowels's General Catalog of Artificial Space Objects includes that information. See the object catalog at https://www.planet4589.org/space/gcat/web/cat/index.html (download links in the menu on the left).

Specifically the length (longest dimension excluding antennas/solar arrays) and span (including everything) columns.
