Struct GnssFix 

pub struct GnssFix { /* private fields */ }

Satellite fix: position, time, method and other receiver data.

Built via GnssFix::builder: most fields are optional and filled differently by different sentences.

Implementations

impl GnssFix

pub const fn builder( taken_at: Instant<Utc>, position: Position, ) -> GnssFixBuilder

Starts a fix from time and position, the two mandatory fields.

With nothing else set it is an autonomous fix.

pub const fn taken_at(&self) -> Instant<Utc>

Fix time, receiver clock, UTC.

pub const fn position(&self) -> Position

Position.

pub const fn course_over_ground(&self) -> Option<TrueCourse>

Course over ground, if reported.

Receivers omit it when stationary, where it is noise.

pub const fn speed_over_ground(&self) -> Option<Speed>

Speed over ground, if reported.

pub const fn quality(&self) -> &GnssQuality

Quality.

pub fn horizontal_accuracy(&self) -> Option<Distance>

Estimated 1σ horizontal error: HDOP × nominal UERE for the fix type.

None without HDOP or for non-satellite positions. A nominal estimate, not a measurement; see GnssFix::horizontal_accuracy_with to supply a UERE.

pub fn horizontal_accuracy_with(&self, uere: Distance) -> Option<Distance>

1σ horizontal error for a given 1σ range error: HDOP × UERE.

None without HDOP.

pub fn observed_position(&self) -> Observed<Position, Distance>

Position as an Observed value, for source-agnostic use cases.

Status by fix type: satellite fix Valid; receiver estimate, manual or simulated Suspect; no fix Invalid. Uncertainty is GnssFix::horizontal_accuracy where available.
