✔✔How many JTIDS/MIDS net numbers are there? - ✔✔127
✔✔Which JTIDS/MIDS access technique is not operator selectable and allows different
groups of users to exchange information in different Network Participation Groups
(NPGs)? - ✔✔Multi-nets
✔✔What is another term for the hopping pattern used by a terminal for a single
transmission? - ✔✔Net

or more different tracks
Two or more tracks representing the same object reported on the interface
Loss of tactical information due primarily to message differences
A unit receives the same data on more than one path
✔✔Mutual Tracking is a plan in which all track-producing units will ___________. -
✔✔(Correct) transmit their track data allowing correlation rules to determine the
reporting responsibility (R2)
✔✔Data Registration is ___________. - ✔✔A condition of correct relative alignment
between local and remote track positional data
Used to divide reporting responsibility
(Wrong) Used to prevent an individual IU data base from being overloaded
(Wrong) The procedure for determining data registration corrective values known as
Position Adjustment System (PADS)
✔✔What type of filter allows an IU to filter data based on geographic location of that
data? - ✔✔(Correct) Geographic Filter
