Atmospheric drag parameters, acceleration, and decay estimates.
Summary
Functions
Estimate the time until the state decays to the reentry altitude.
Functions
@spec acceleration(Sidereon.Drag.Parameters.t(), Sidereon.Astro.Relative.State.t()) :: {:ok, {float(), float(), float()}} | {:error, atom() | Sidereon.argument_error()}
@spec default_space_weather() :: Sidereon.Drag.SpaceWeather.t()
@spec estimate_decay( Sidereon.Astro.Relative.State.t(), Sidereon.Drag.Parameters.t(), keyword() ) :: {:ok, Sidereon.Drag.DecayEstimate.t()} | {:error, term()}
Estimate the time until the state decays to the reentry altitude.
Options: :force_model (default :twobody), :abs_tol, :rel_tol,
:reentry_altitude_km, :scan_step_s, :crossing_tolerance_s,
:max_duration_s, :max_scan_samples, :space_weather_table (a
Sidereon.SpaceWeather table the drag inputs are read from along the arc)
and :space_weather_policy (a Sidereon.SpaceWeather.Policy or keyword list
the table is read under; without it the table is read under the default
policy, which refuses Ap values the file does not state and rows with no
flux observation).
@spec from_area_mass(number(), number(), number(), keyword()) :: {:ok, Sidereon.Drag.Parameters.t()} | {:error, atom() | Sidereon.argument_error()}
@spec from_ballistic_coefficient( number(), keyword() ) :: {:ok, Sidereon.Drag.Parameters.t()} | {:error, atom() | Sidereon.argument_error()}
@spec from_bc_factor( number(), keyword() ) :: {:ok, Sidereon.Drag.Parameters.t()} | {:error, atom() | Sidereon.argument_error()}
