Returns a property function that checks to be sure the value being assigned is a certain class before assigning it to a hidden variable define

Extracts the number of orbits per day from the tle and calcualtes the time per orbit in minutes

Checks that the list contains the same number of elements as the number of TLEs. If None, default to a list of Nones.

Generates a datetime property that handles strings and timezones.

Adds (or updates) instance of Satellite

Creates the satellite marker (i.e. billboard)

Checks if color is valid or generates a random one

Checks if TLE has either 2 or 3 records [name (optional), TLE1, TLE2]

Checks if TLE has a name by seeing if 3 records exist (name, TLE1, TLE2) when name_list is None

Creates the satellite label

Builds the lead and trail time for the orbit path

Creates the satellite positions and settings

Set the random seed. Only effects satellites not yet added.

Sets the speed multiplier (how fast the satellites move)

Sets the start and end time

Default init functionality is to load kwargs
