Purpose

a. To provide Navy policy governing positioning, navigation, and timing (PNT) and navigation warfare (NAVWAR) matters per reference (a) and implementation of guidance described in references (b) through (h).

b. To assign PNT responsibility to specific Navy organizations for requirements development, acquisition, installation, testing, certification, training, sustainment, and operational use of PNT and NAVWAR systems at sea and ashore.

c. This revision affirms established and newly established policies, more clearly defines the pillars of PNT - to include renewed interest and recapitalization for celestial navigation - and delineates the relationships and responsibilities to specific Navy organizations for more assured PNT navigational standardization and superiority. This instruction is a major revision and should be reviewed in its entirety.
