Jtids-201 Unit 9 - Data Forwarding
Questions With Solutions
What are the two types of data forwarding? Straight Data Forwarding
Message Translation
What is the exception to straight data forwarding? When during forwarding between an
RF network and a JREAP network. During
this process J2.X messages are forwarded as J2.0 messages
Provide an example of when message translation forwarding would occur. Translated data
forwarding would be from Link 11 to Link 16. Link 11 messages have to be mapped to Link 16
messages to keep the original intent of the Link 11 message.
In the case of Link 11 to Link 16 message forwarding, there will be no loss of data, since the
Link 16 message incorporates all data possible in a like Link 11 message.
What drives the MTN architecture and will determine what data must flow to which units?
IERs
True or False: When translating from a less capable message standard to a more capable one,
data can be added in order to complete the message. False: When translating from a less
capable message standard to a more capable one, data is not added.
, What seven basic track IDs do Link 16 J-Series messages support? Pending, Unknown,
Friend, Assumed Friend, Neutral, Suspect, and Hostile.
What four basic IDs do Link 11/11B M-Series messages support? Friend (1), Friend (3),
Unknown, and Hostile
J-Series messages report surveillance track position using what coord grids?
What about M-Series messages? J-SERIES: WGS-84 referenced latitude (32ft), longitude
(32ft), and altitude (25ft)
M-SERIES: The Cartesian coordinate granularities are 1500ft x 1500ft
x 500ft.
What environment messages do M-Series messages not support? space and land
The differing bandwidths typically associated with various TDLs can induce what into the MTA?
data latency
What allow one or more units to receive the same information from more than one data path and
can occur on a JREAP heavy architecture? Data Looping
