A client device may identify a first parameter that is to be updated periodically and a second parameter that is to be updated based on a state change. The client may transmit, via a negotiation session, a request to the server device. The request indicates that the server device is to periodically provide information indicating a current value of the first parameter and is to provide information indicating an updated value of the second parameter when a state of the second parameter changes. The client device may periodically receive, from the server device and via a second communication protocol, a first datagram including the current value of the first parameter and may receive a second datagram including the updated value of the second parameter based on the server device determining that the current state of the second parameter has changed.

Communicating parameters based on a change

The disclosure describes, in one aspect, a method for determining a machine ground speed. The method includes determining a machine speed from a position determining system, the machine speed includes a horizontal speed component and a vertical speed component, determining a direction the machine is moving at the machine speed, determining a machine inclination angle, determining a machine rate of inclination, and determining a compensated ground speed as a function of the horizontal speed component, the vertical speed component, the direction, the machine inclination angle, and the machine rate of inclination.
