Data:

sensor_gps_fix_t fix_type: GPS fix of type sensor_gps_fix_t that specifies the status of the GPS fix.
double latitude: Latitude in degrees based on WGS84 ellipsoidal coordinate system.
double longitude: Longitude in degrees based on WGS84 ellipsoidal coordinate system.
int32_t altitude: Altitude (height above ellipsoid) in millimeters based on WGS84 ellipsoidal coordinate system.
int32_t velocity[3]: Velocity in the x, y, and z directions, in mm/s.; MAX_INT32 indicates value is currently unavailable.
uint32_t velocity_time_offset: Offset from the timestamp in sensor_buffer_t to apply for the velocity field only.; Time is provided in microseconds and will be zero when velocity is in sync with GPS data.
uint32_t time_offset: Offset from the timestamp in sensor_buffer_t to apply for this data point.
uint32_t time_accuracy: Time accuracy estimate, in ns.
uint16_t gdop: Geometric degree of precision.
uint16_t pdop: Position degree of precision.
uint16_t tdop: Time degree of precision.
uint16_t vdop: Vertical degree of precision.
uint16_t hdop: Horizontal degree of precision.
uint32_t latitude_std_deviation: Latitude standard deviation, in mm.
uint32_t longitude_std_deviation: Longitude standard deviation, in mm.
uint32_t altitude_std_deviation: Altitude standard deviation, in mm.
uint32_t speed_std_deviation: Speed standard deviation, in mm/s.
sensor_utc_time_t utc: Universal Time Coordinated (UTC) current time.

Library:

libsensor

Description:
