JTIDS 2026 CORE EXAM TEST QUESTIONS AND ANSWERS
GUARANTEE A+
✔✔Which statement/statements regarding PPLIs is accurate? - ✔✔*NOT* In RELNAV
operations, a position quality of 0 is the most accurate

*OR*
Secondary User (SU)
*OR*
Passive unit

✔✔Correctly choose the data registration process and its description
a)Process in which a JTIDS/MIDS Unit (JU) monitors and adjusts positional data with
information derived through Relative Navigation (RELNAV).
b)Process that corrects alignment of the sensor elements used for the measurement of
a tracked object's position.
