Detailed Description

GNSS observations for a particular satellite signal.

Pseudorange and carrier phase observation for a satellite being tracked. The observations are interoperable with 3rd party receivers and conform with typical RTCM 3.1 message GPS/GLO observations.

Carrier phase observations are not guaranteed to be aligned to the RINEX 3 or RTCM 3.3 MSM reference signal and no 1/4 cycle adjustments are currently peformed.

Field Documentation

u8 cn0

Carrier-to-Noise density.

Zero implies invalid cn0. [dB Hz / 4]

Definition at line 72 of file observation.h.

doppler_t D

Doppler observation with typical sign convention.

[Hz]

Definition at line 71 of file observation.h.

u8 flags

Measurement status flags.

A bit field of flags providing the status of this observation. If this field is 0 it means only the Cn0 estimate for the signal is valid.

Definition at line 80 of file observation.h.

carrier_phase_t L

Carrier phase observation with typical sign convention.

[cycles]

Definition at line 70 of file observation.h.

u8 lock

Lock timer.

This value gives an indication of the time for which a signal has maintained continuous phase lock. Whenever a signal has lost and regained lock, this value is reset to zero. It is encoded according to DF402 from the RTCM 10403.2 Amendment 2 specification. Valid values range from 0 to 15 and the most significant nibble is reserved for future use.

Definition at line 73 of file observation.h.

u32 P

Pseudorange observation [2 cm].

Definition at line 69 of file observation.h.

sbp_gnss_signal_t sid

GNSS signal identifier (16 bit)

Definition at line 84 of file observation.h.
