Looks interesting, Micaël.  One immediate problem is that El Capitan has a much stricter attitude to networking that earlier Mac OS X versions.  Specifically, the connection to 'www.celestrak.com' is not secured, generating the error:

   Connecting to: http://www.celestrak.com/NORAD/elements/visual.txt
   Connection failed with error: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.

stops the loading of TLEs.  This ATS policy is quite strict but can be defeated with plist entries (though, I’d bet that in a year or two, that option will be closed out too).  I hit the same problem with my app and the following addition to Info.plist fixed it:

	<key>NSAppTransportSecurity</key>
	<dict>
		<key>NSExceptionDomains</key>
		<dict>
			<key>celestrak.com</key>
			<dict>
				<key>NSIncludesSubdomains</key>
				<true/>
				<key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
				<true/>
			</dict>
		</dict>
	</dict>

Note that 'space-track.org' does use a secure transport and does work correctly.  Let me know if you need more details .. Gavin

The ultimate solution is for 'www.celestrak.com' to offer a secure connection option.  I’ve been meaning to bring this to Kelso’s attention but haven’t found the time yet.
