mavsdk::Telemetry::RawGps Struct Reference

#include: telemetry.h

Raw GPS information type.

Warning: this is an advanced type! If you want the location of the drone, use the position instead. This message exposes the raw values of the GNSS sensor.

Data Fields

uint64_t timestamp_us {} - Timestamp in microseconds (UNIX Epoch time or time since system boot, to be inferred)

double latitude_deg {} - Latitude in degrees (WGS84, EGM96 ellipsoid)

double longitude_deg {} - Longitude in degrees (WGS84, EGM96 ellipsoid)

float absolute_altitude_m {} - Altitude AMSL (above mean sea level) in metres.

float hdop {} - GPS HDOP horizontal dilution of position (unitless). If unknown, set to NaN.

float vdop {} - GPS VDOP vertical dilution of position (unitless). If unknown, set to NaN.

float velocity_m_s {} - Ground velocity in metres per second.

float cog_deg {} - Course over ground (NOT heading, but direction of movement) in degrees. If unknown, set to NaN.

float altitude_ellipsoid_m {} - Altitude in metres (above WGS84, EGM96 ellipsoid)

float horizontal_uncertainty_m {} - Position uncertainty in metres.

float vertical_uncertainty_m {} - Altitude uncertainty in metres.

float velocity_uncertainty_m_s {} - Velocity uncertainty in metres per second.

float heading_uncertainty_deg {} - Heading uncertainty in degrees.

float yaw_deg {} - Yaw in earth frame from north.
