Expand description

Predicted GNSS observables at one receive epoch.

Fields§

§geometric_range_m: f64

Geometric range after optional Sagnac rotation, meters.

§range_rate_m_s: f64

Range-rate LOS projection, meters per second.

§doppler_hz: f64

Doppler shift at PredictOptions::carrier_hz, hertz.

§sat_clock_s: Option<f64>

Satellite clock offset at transmit time, seconds.

§elevation_deg: f64

Topocentric elevation, degrees.

§azimuth_deg: f64

Topocentric azimuth in [0, 360), degrees.

At (and arbitrarily near) the receiver’s zenith the azimuth is geometrically undefined; it is defined here to be exactly 0.0 once the horizontal line-of-sight projection falls below crate::constants::AZIMUTH_ZENITH_EPS, rather than returning rounding noise or erroring.

§transmit_offset_us: i64

Transmit-time offset from receive time, rounded to microseconds.

§transmit_time_j2000_s: f64

Transmit time as seconds since J2000.

§los_unit: [f64; 3]

Receiver-to-satellite line-of-sight unit vector in ECEF.

§sat_pos_ecef_m: [f64; 3]

Sagnac-rotated satellite ECEF position in meters.

§sat_velocity_m_s: [f64; 3]

Sagnac-rotated satellite ECEF velocity in meters per second.
