Properties

Name	Type	Description
timestamp	object	Timestamp of the message
frame_id	string	Frame for the sensor. Latitude and longitude readings are at the origin of the frame.
latitude	number	Latitude in degrees
longitude	number	Longitude in degrees
altitude	number	Altitude in meters
position_covariance	array	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.
position_covariance_type	object	If `position_covariance` is available, `position_covariance_type` must be set to indicate the type of covariance.
heading	number	Heading (yaw angle), in radians, measured clockwise from north
velocity	object	Velocity in local East-North-Up (ENU) frame in m/s
color	object	Color used to visualize the location
metadata	array	Additional user-provided metadata associated with the location fix. Keys must be unique.
