struct LocationFix¶

A navigation satellite fix for any Global Navigation Satellite System.

Public Types

enum class PositionCovarianceType : uint8_t¶

Type of position covariance.

Values:

enumerator UNKNOWN¶: Unknown position covariance type.

enumerator APPROXIMATED¶: Position covariance is approximated.

enumerator DIAGONAL_KNOWN¶: Position covariance is per-axis, so put it along the diagonal.

enumerator KNOWN¶: Position covariance of the fix is known.

Public Members

std::optional<foxglove::Timestamp> timestamp¶: Timestamp of the message.

std::string frame_id¶: Frame for the sensor. Latitude and longitude readings are at the origin of the frame.

double latitude = 0¶: Latitude in degrees.

double longitude = 0¶: Longitude in degrees.

double altitude = 0¶: Altitude in meters.

std::array<double, 9> position_covariance¶: Position covariance (m^2) defined relative to a tangential plane through the reported position. The components are East, North, and Up (ENU), in row-major order.

PositionCovarianceType position_covariance_type¶: If position_covariance is available, position_covariance_type must be set to indicate the type of covariance.
