What messages are used to input navigational information to the network?

• A. RTT only
• B. RTT and unit navigational inputs
• C. GPS corrections only
• D. RTT, unit navigational inputs, and GPS corrections

Answer: (B)

The navigational information fed into the Link 16 network comes from two sources: RTT messages and unit navigational inputs. RTT messages provide the timing framework and range-related data that help synchronize the network’s shared navigation picture, while unit navigational inputs supply each platform’s current position, velocity, altitude, and heading to the network. GPS corrections, while useful for improving an individual receiver’s position solution, aren’t broadcast as navigational inputs to populate the network’s shared navigation state. So the combination of RTT and unit navigational inputs is what input navigational information to the network.
