}

A decoded GPS broadcast ephemeris (message 1019).

Angular quantities are in semicircles (scale noted per field), harmonic correction terms in radians, distances in meters, and clock terms in seconds, each recovered by multiplying the raw integer by its scale factor.

Trait Implementations

impl Clone for GpsEphemeris

fn clone(&self) -> GpsEphemeris

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for GpsEphemeris

impl Debug for GpsEphemeris

fn fmt(&self, f: &mut Formatter<'_>) -> Result
