## G.2.  Definitions.

These terms and their definitions are for the purpose of this issuance.

TERM
DEFINITION
CRF
The fundamental set of observable physical parameters defining natural celestial objects required for position, navigation, and timing and related defense applications.  This includes the fundamental reference system and relevant frame or frames (i.e., the realization of the reference system using observable celestial objects).  It also
includes all celestial objects referenced to the underlying reference frame used by defense systems for purposes of position, navigation, timing, guidance, orientation, space domain situational awareness, defense system calibration, and targeting applications.  The minimum
set of observable physical parameters consists of the positions, motions, and brightness (as a function of wavelength) of celestial objects.  The DoD Components' utilization of the CRF includes, but is not limited to, the purposes of determining objects of interest's positions, orientations, motions, orbits, and intent; exquisite calibration of defense sensors; and determination of platform and instrument orientation for purposes of intelligence collection, targeting and system guidance.
EOP
The values that describe the mathematical relationship between the TRF and the CRF.  This relationship is defined by the coordinates of
the Earth's pole (polar motion), the rotation angle about the pole
(Universal Time or UT1), precession, and nutation.
leap second
Time is occasionally adjusted by 1-second increments to ensure that
the difference between a uniform time scale defined by atomic clocks does not differ from the Earth's rotational time by more than 0.9 seconds.  In order to keep this cumulative difference less than 0.9 seconds, a leap second is added to the atomic time to decrease the difference between the two.  This leap second can be either positive
or negative depending on the Earth's rotation.
TERM
DEFINITION
Master Clock
The underlying product for all PTTI products.  The single authoritative clock providing the real time representation of Coordinated Universal Time for all of DoD.  An ensemble of clocks maintained at the USNO is used to ensure the accuracy and consistency of the authoritative clock.
PNT forum
A meeting or conference venue at which PNT matters are formal agenda topics.
precise time
A frequency (time interval) requirement accurate to within 1 microsecond.
PTTI
A reference value of time and time interval (frequency).
