Expand description

Store a trajectory of any State.

Fields§

§segments: BTreeMap<i32, Spline<S>>

Splines are organized as a binary tree map whose index is the number of seconds since the start of this ephemeris rounded down

Implementations§

source §

impl<S: InterpState> Traj<S>where DefaultAllocator: Allocator<f64, S::VecLength> + Allocator<f64, S::Size> + Allocator<f64, S::Size, S::Size>,

source

pub fn at(&self, epoch: Epoch) -> Result<S, NyxError>

Evaluate the trajectory at this specific epoch.

source

pub fn first(&self) -> S

Returns the first state in this ephemeris

source

pub fn last(&self) -> S

Returns the last state in this ephemeris

source

pub fn every(&self, step: Duration) -> TrajIterator<'_, S>

Creates an iterator through the trajectory by the provided step size

source

pub fn every_between( &self, step: Duration, start: Epoch, end: Epoch ) -> TrajIterator<'_, S>

Creates an iterator through the trajectory by the provided step size between the provided bounds

source

pub fn find_bracketed<E>( &self, start: Epoch, end: Epoch, event: &E ) -> Result<S, NyxError>where E: EventEvaluator<S>,

Find the exact state where the request event happens. The event function is expected to be monotone in the provided interval.

source

pub fn find_all<E>(&self, event: &E) -> Result<Vec<S>, NyxError>where E: EventEvaluator<S>,

Find (usually) all of the states where the event happens. WARNING: The initial search step is 1% of the duration of the trajectory duration! For example, if the trajectory is 100 days long, then we split the trajectory into 100 chunks of 1 day and see whether the event is in there. If the event happens twice or more times within 1% of the trajectory duration, only the one of such events will be found.

source

pub fn find_minmax<E>( &self, event: &E, precision: Unit ) -> Result<(S, S), NyxError>where E: EventEvaluator<S>,

Find the minimum and maximum of the provided event through the trajectory

source §

impl Traj<Orbit>

source

pub fn to_frame( &self, new_frame: Frame, cosm: Arc<Cosm> ) -> Result<Self, NyxError>

Allows converting the source trajectory into the (almost) equivalent trajectory in another frame

source

pub fn to_csv_with_step( &self, filename: &str, step: Duration, cosm: Arc<Cosm> ) -> Result<(), NyxError>

Exports this trajectory to the provided filename in CSV format with the default headers and the provided step

source

pub fn to_csv_between_with_step( &self, filename: &str, start: Option<Epoch>, end: Option<Epoch>, step: Duration, cosm: Arc<Cosm> ) -> Result<(), NyxError>

Exports this trajectory to the provided filename in CSV format with the default headers and the provided step

source

pub fn to_csv(&self, filename: &str, cosm: Arc<Cosm>) -> Result<(), NyxError>

Exports this trajectory to the provided filename in CSV format with the default headers, one state per minute

source

pub fn to_csv_between( &self, filename: &str, start: Option<Epoch>, end: Option<Epoch>, cosm: Arc<Cosm> ) -> Result<(), NyxError>

Exports this trajectory to the provided filename in CSV format with the default headers, one state per minute

source

pub fn to_groundtrack_csv( &self, filename: &str, body_fixed_frame: Frame, cosm: Arc<Cosm> ) -> Result<(), NyxError>

Exports this trajectory to the provided filename in CSV format with only the epoch, the geodetic latitude, longitude, and height at one state per minute. Must provide a body fixed frame to correctly compute the latitude and longitude.

source

pub fn to_csv_custom( &self, filename: &str, headers: Vec<&str>, step: Duration, cosm: Arc<Cosm> ) -> Result<(), NyxError>

Exports this trajectory to the provided filename in CSV format with the provided headers and the provided step
