12 CHANNEL POSITION/STATUS/DATA MESSAGE (@@Ha)
This message is the ‘standard’ M12+ binary position/status message. The @@Ha message
provides position and channel related data to the user at a specified update rate.
Default mode: Polled
Note: United States export laws prohibit commercial GPS receivers from outputting valid data if
the calculated GPS height is greater than 18,000 meters (11 miles) and the calculated 3D
velocity is greater than 514 meters/second (1135 miles/hour). If the receiver is used
above both of these limits concurrently, the height and velocity outputs are clamped to
the maximum values. In addition, the latitude and longitude information will be incorrect.
