Load Elsets into SatSpy

Once you have downloaded fresh elsets and started SatSpy, you can open one or more elset files. SatSpy reads elsets from ASCII files containing standard NORAD 3-line elsets (one line is the satellite name and the other two are the elsets). Elset loading is achieved at the click of a button:

You can load one elset file at a time. Or..
You can append additional files to those already opened. When you append and elset file, SatSpy checks each new elset to see if it is a duplicate of one already loaded. If so, it checks the ages of the elsets and keeps the youngest of the two.

Optionally, you can instruct SatSpy to load multiple elsets, each with a different epoch, for a single satellite. This is useful when you wish to analyze the behavior of a satellite's orbit over time.
