The TLE structure

When a TLE is parsed using this package, the information is encapsulated in the structure TLE. Its fields are:

• name::String: Name of the satellite.
• satellite_number::Int: Satellite number.
• classification::Char: Classification ('U', 'C', or 'S').
• international_designator::String: International designator.
• epoch_year::Int: Epoch year (two digits).
• epoch_day::Float64: Epoch day (day + fraction of the day).
• dn_o2::Float64: 1st time derivative of mean motion / 2 [rev/day²].
• ddn_o6::Float64: 2nd time derivative of mean motion / 6 [rev/day³].
• bstar::Float64: B* drag term.
• element_set_number::Int: Element set number.
• incliantion::Float64: Inclination [deg].
• raan::Float64: Right ascension of the ascending node [deg].
• eccentricity::Float64: Eccentricity [ ].
• argument_of_perigee::Float64: Argument of perigee [deg].
• mean_anomaly::Float64: Mean anomaly [deg].
• mean_motion::Float64: Mean motion [rev/day].
• revolution_number::Int: Revolution number at epoch [rev].

Notice that we preserve the units of the TLE definition.
