uint8 frame # The coordinate system of the fields: x, y, z.
float64 x # X coordinate of center point. Coordinate system depends on frame field: local = x position in meters * 1e4, global = latitude in degrees * 1e7.
float64 y # Y coordinate of center point. Coordinate system depends on frame field: local = y position in meters * 1e4, global = latitude in degrees * 1e7.
float32 z # Altitude of center point. Coordinate system depends on frame field.
