Jt-102 Surveillance Track Production (Unit
24) Questions With Answers
During TN Assignment, if a unit has both a low and high TN allocation blocks
assigned, how does the system assign a TN? The high block will be used if there are no
low TNs available
What is a numerical value representing the horizontal positional reliability within a 95%
confidence level? Track Quality (TQ)
In Time Quality, what value is not considered in the Track Quality calculation? Altitude;
TQ is only a 2-dimentional value
What are the legal Link 11/11B Track Qualities? Link-11 has a TQ of 0-7 while Link 16
TQs range from 0-15
What is a U.S. Navy only capability allowing units to artificially limit the highest track quality
Track Quality it can have on a track? Variable TQ, or "dial-a-TQ"
Why does the USN use VTQ? It can (1) direct R2 to platforms with more capable sensors
(2) control R2 shifts
, (3) give a Gridlock Reference Unit (GRU) a sufficient number of tracks
(4) mitigate surveillance capacity and TN allocation shortages.
What is the determination a system track or local sensor track data report represents the same
object or point as another track and/or the process of combining two such tracks/data under one
track number? Correlation
When two tracks are correlated, they become what is known as a _______________
_______________. Common track.
What are the track update rates for both Air and surface tracks, and, land tracks? Air and
surface tracks = 12 seconds
Land tracks = 48 seconds
What automatic tests are performed when the correlation process begins? • Position
(including altitude for air tracks)
• Kinematics (course and speed)
• Mode 2 (can be disabled by operator)
• Identification
