| double longitude | Longitude information. A positive value indicates east longitude, and a negative value indicates west longitude. The value ranges from -180 to 180. Only the WGS84 coordinate system is supported. |
| double altitude | Location altitude, in meters. |
| double accuracy | Location accuracy, in meters. |
| double speed | Speed, in m/s. |
| double direction | Direction information. The value ranges from 0 to 360, in degrees. |
| int64_t timeForFix | Location timestamp in the UTC format. |
| int64_t timeSinceBoot | Location timestamp since boot, in nanosecond. The value is the duration from the time when the device is booted to the time when the location is obtained. This means that the timestamp is reset each time the device is restarted. |
| double altitudeAccuracy | Height accuracy, in meters. |
| double speedAccuracy | Speed accuracy, in m/s. |
| double directionAccuracy | Direction accuracy. The value ranges from 0 to 360, in degrees. |
| int64_t uncertaintyOfTimeSinceBoot | Uncertainty of the location timestamp (that is, timeSinceBoot), in nanosecond. |
| Location_SourceType locationSourceType | Source of the location result. For details, see Location_SourceType. |
