4-3 shows a pictorial diagram of the Link 11 circuit.
NAVIGATION SUBSYSTEM
The navigation subsystem provides the combat
system with accurate own-ship position anywhere in the
world and the navigational information needed to
maneuver own ship safely. It also provides an
identity-coded TACAN beacon signal to enable aircraft
to determine their range and bearing in relation to own
ship.
The navigation subsystem uses shipboard,
shorebased, and aircraft electronic equipment to
accomplish its supporting mission. The shipboard
navigation subsystem is made up of the following
equipment:
1.
2.
3.
4.
Sonar Sounding Set AN/UQN-4
Satellite Navigation Set AN/SRN-19
TACAN Set AN/URN-25
Dead Reckoning System
Figure 4-4 shows a pictorial diagram of the
navigation subsystem.
SUPPORT SUBSYSTEM
The following systems and equipment compose the
support subsystem:
1.
2.
3.
4.
5.
6.
Dry air and nitrogen
Liquid cooling and heating
Ship parameters and distribution (own-ship
heading, roll, and pitch, own-ship speed and
distance, and wind speed and direction)
Ship power and distribution
Air conditioning and heating
Interior communications
COMBAT SYSTEMS TEST AND
EVALUATION PROGRAM (CSTEP)
The Combat Systems Test and Evaluation Program
(CSTEP) is a combination of special teams, tests,
evaluations, publications, and reports used to promote
the effectiveness of shipboard combat systems.
Basically, the program is designed to
1. increase the priority and focus given to combat
systems during overhauls and selected restricted
availabilities (SRAs);
